– On July 2008, Michael Roseboro, now 52, killed his wife Jan, 45, by strangling, beating and drowning her in their private swimming pool.

Michael Roseboro threw up while he was at the phone with the 911 operator he called to notify that his wife had drowned.

Nausea and vomiting are classical responses to a prolonged stress. Stress can induce general trouble with the digestive system due to the physiological changes a body goes through.

Not only the victim of a sexual violence or of an aggression but also the perpetuator often shows the symptoms of the so called General Adaptation Syndrome (GAS), a physiological reaction to a stressful event. 

GAS is a three-stage process that a body goes through when under stress: Alarm, Resistance and Exhaustion.

Alarm reaction stage: corticoids, adrenaline and noradrenaline are released to induce a a “fight-or-flight” response that allows the body to deal with the threat.

Resistance stage: at the end of a stressful situation, the body enters in a recovery phase to reach the pre stress state.

When the stress is prolonged the body is unable to recover and continues to release corticoids, adrenaline and noradrenaline. Stomach and intestinal distresses like nausea, vomiting, diarrhea and bloating are symptoms of this prolonged state of alert.

Exhaustion stage: when the stress is chronic a subject deals with symptoms like depression, anxiety and fatigue.

A murderer is in a prolonged state of alert because his/her fear of being caught.


The Coleman’s family

Columbia, Illinois.

At 6:43 a.m. on May 5, 2009, Christopher Coleman, who was employed as director of security for Joyce Meyer Ministries (JMM), an internationally renowned Christian ministry headquartered in Missouri, called his neighbor, Detective Sergeant Justin Barlow of the Columbia police department and told him he had been at the gym and after his workout he called home to try to wake up his wife, Sheri, but Sheri did not answer. Christopher Coleman was concerned something had happened to his wife. Barlow was aware that defendant had made previous reports to the Columbia police department that he and his family had been threatened due to his employment with JMM. Sergeant Barlow went to Coleman’s house to check on the welfare of the family. Soon another officer arrived, and after ringing the doorbell and receiving no answer, they went to the back of the house and saw a basement rear window standing open. 

Christopher Coleman arrived home and was told to stay outside. The police entered the home through the basement window and saw disturbing messages written on the walls in red spray paint, including the word “fuck” and the words “I am always watching”; when they went up the stairs to the second floor, they found Christopher Coleman’s sons Garett, 11, Gavin, 9, and his wife Sheri, 31, dead. They had been strangled in their sleep. Gavin was lying in his bed with the words “Fuck You” spray-painted on the covers. A policeman also noticed spray paint on Garett’s hand and arm. 

After the officers heard Coleman downstairs asking what was going on, they went downstairs.

Detective Justin Barlow of the Columbia Police Department and a neighbor, who entered Coleman’s house and found the body of Gavin said to 48 Hours correspondent Maureen Maher: I told him (Christopher Coleman): “Hey, they… they didn’t make it”… being the family, he walked outside through the garage, he sat down on the driveway and started sobbing. Said he felt like he was gonna throw up. And then kind of curled up in a fetal position.

Barlow recalls Coleman asking him what happened, but nothing else. He did not demand to see his family, nor did he try to go upstairs. He went outside with the officers and sat on the sidewalk and cried, but Barlow testified no one told him what they actually had found upstairs. Coleman remained at the scene for approximately 20 to 25 minutes until he was taken by ambulance to the police station, where he was interviewed for 6 hours. Defendant did not ask how his family was killed. Approximately 4 hours into the interview, Trooper Bivens, the other officer conducting the interview besides Barlow, specifically asked Coleman if he knew how his family died. He replied: “I have no idea, you guys haven’t told me”.

During the interview, Coleman asked for a blanket because he was cold though Barlow did not think the interview room was cold. At one point during the interview, officers walked out of the room and Coleman picked up one of the officer’s notes and looked at them. With the blanket Coleman covered some scratches he had on his arm. He said he obtained one set of scratches a few days earlier, but was unsure how he got them. He said he received another abrasion on his arm after hitting his arm on the gurney in the ambulance in which he was transported after his family was found dead.

Christopher Coleman told investigators his wife Sheri was alive when he left the house at 5:45 a.m. to go to the gym. He told the police his marriage was good, but later revealed that near the end of 2008, he and Sheri had some problems in their marriage, which they worked out through the help of counseling. Detectives soon discovered he was having an affair with Tara Lintz, a high school friend of Sheri’s who was living in Florida. Christopher Coleman denied the affair, but after being advised investigators were talking to Tara, he admitted to the affair, but minimized its intensity. 

Medical reports, including the results of the autopsies, showed that Sheri, Garett, and Gavin were all dead before 5 a.m. Police checked Christopher Coleman’s cell phone records and investigated where his calls were placed on the morning of the murders. Based upon the foregoing, Coleman was charged with three counts of first-degree murder by strangulation.

After a jury trial in the circuit court of Monroe County, Christopher Coleman was convicted and sentenced to three concurrent life sentences.

Christopher Coleman

After the sentence, 48 Hours Mystery spoke to Chris Coleman by phone:

Maureen Maher: Did you kill your wife and your children?

What we look for in the following answer is for Coleman to issue a reliable denial.

A reliable denial is found in the free editing process, not in the parroted language and has 3 components:

1. the pronoun “I”
2. past tense verb “did not” or “didn’t”
3. accusation answered

If a denial has more than 3 or less than 3 components, it is no longer reliable.

There is no consequence to issue a reliable denial about any false allegation.

“I did not kill my wife Sheri and my children” followed by “I told the truth” while addressing the denial, it is more than 99% likely to be true. This would be the “wall of truth”. 

The “wall of truth” is an impenetrable psychological barrier that often leads innocent people to few words, as the subject has no need to persuade anyone of anything.

We begin every statement analysis expecting truth, and it is the unexpected that confronts us as possibly deceptive.

Chris Coleman: No, absolutely not. I absolutely love my wife and my kids. And this, you know, it’s not… it’s not me.

“No, absolutely not” is an unreliable denial.

The words “absolutely not. I absolutely love my wife and my kids. And this, you know, it’s not… it’s not me” show that Coleman has a need to persuade and to portrait himself as a “good guy”. Only a “bad guy” feels this need. 

There is not “wall of truth” within Christopher Coleman.

Moreover when he says “And this” he shows closeness to the murders.

Maureen Maher: How do you love your wife and be having an affair with one of her best friends?

Chris Coleman: Maybe I wasn’t, you know, selfishly getting what I thought I might should be getting at home as far as with my wife, you know, from the uh… physical side of things. But I still absolutely loved her.

The word “with” used between people speaks of distance.

The words “still absolutely show that Coleman has a need to persuade.

Maureen Maher: So why does Tara say that?

Chris Coleman: Uhm, it was discussed on several different things and, you know, it was a conversation but there was no specific plans or no dates or nobody asking each other to be married or anything like that.

Maureen Maher: She also says that you told her that you were serving divorce papers to Sheri.

Chris Coleman: You know, unfortunately, and I feel horrible about it, you know, if I ever talk to… to Tara again of something like that I apologize to her about, that was a lie. I lied to Tara about that.

Maureen Maher: So if he didn’t murder his family, who did?

These are Maher’s words, Coleman never issued a reliable denial.

Chris Coleman: I have absolutely no clue. Believe me, I have wracked my brain for… for two-and-a-half years trying to figure that part out (laughs). I just had to stop and give it to God, just to release that, do my best and forgive… forgive that person and move on.

The words “absolutely” and “Believe me” show a need to persuade, again.

Coleman’s laughs is a signal of an Antisocial personality disorder.

Note Coleman linguistic disposition toward the killer: a persone to forgive.


Karen Pannell and two of her brothers

Pensacola, Florida.

On October 11, 2003, Karen Ann Pannell, 39, was found stabbed to death in her Florida home.

Karen Ann Pannell was a former model and Flight Attendant. At the time of her death she was working for American Airlines as a Customer Service Agent in Tampa, Florida.

She had five brothers, Michael A., Randy, Steve, Michael R. and Robin.

Timothy Permenter, Karen’s boyfriend was the one to call 911. His phone call is incriminating.

Investigators, while processing the crime scene, noted the name ROC written in blood on the wall and a pizza box with three slices missing. According with the autopsy Karen had not eaten pizza on the night of the murder.

ROC is the name of one of Karen ex boyfriends that had an alibi.

Detectives assumed that the killer had eaten the pizza, then after a confrontation he had stabbed Karen 16 times and staged the crime scene to frame Karen’s ex ROC.

Ltd. Michael Holbrooke, the homicide detective who led the investigation on the case said in an interview to Dateline: “When the first deputy arrived on scene Tim Permenter is in the front yard he is hysterical he actually threw up in the front yard that he was upset of finding his girlfriend”.

Timothy Permenter during his trial

Analysis of some excerpts from Timothy Permenter’s interview with detectives:

We look for Permenter to say “I didn’t kill Karen” using the pronoun, “I”, the past tense “didn’t” or “did not” and add in the specific accusation.

Timothy Permenter: I didn’t do it. But I knew somehow, some way I was gonna get pinned on it. I knew it. I knew the minute I saw the body. 

When Permenter says “I didn’t do it” he doesn’t deny the action of killing, therefore  this is an unreliable denial. 

Timothy Permenter: I don’t know. Go ahead. take me to jail. I’m done.

Detective: Tim, I’m not here to railroad you, I’m… I’m not okay?

Timothy Permenter: It doesn’t matter. I’ll tell you something, I didn’t do it and if I’m gonna be convicted, I wanna go to the electric chair because I’m not spending any more time in prison. I’m done with that. Not for something… not for something like this.

“I didn’t do it” is an unreliable denial.

Permenter says “if I’m gonna be convicted”, this is something that never cross the mind of an innocent de facto.

When Permenter says “not for something like this” he shows closeness to the homicide due to the use of the word “this”.

At the time of Karen murder, Timothy Permenter had served 12 years in prison for kidnapping and attempted murder.

Timothy Permenter: I didn’t do it. I d-i-d n-o-t do it. I don’t know how else… how else to say.

“I didn’t do it” is an unreliable denial.

Detective: How does it look? You’re over there when you said you weren’t.

Timothy Permenter: I don’t know.

Timothy Permenter: This whole cooperation got me confused.

Detective: Confused? We know what get you confused, Tim, when you lie.

On October 24, 2007, a jury convicted Timothy Permenter of the first-degree murder of his girlfriend Karen Ann Pannell. The jury voted seven to five in favor of the death penalty, but the trial court sentenced Permenter to life in prison without the possibility of parole.


Jan E. Binkley and Michael Alan Roseboro

Reinholds, Pennsylvania.

Jan E. Binkley Roseboro, 45, a mother of four, was killed on the night of July 22, 2008.

At 11:03 pm, her husband, funeral director, Michael Roseboro called 911 to notify the operator that she had drowned.

During the emergency call Michael Roseboro showed deception and guilty knowledge of what happened to Jan.

He never asked for any help for his wife, nor he showed any linguistic concern for her, nor he showed any urgency.

He never introduces his wife as expected. The social introduction is a key to understand a relationship. His linguistic disposition towards his wife tells us that they had a poor relationship at the time of the call.

He said twice “I’m sorry”. “I’m sorry” represents a verbal indicator of a form of regret.

He invoked “God” twice. Any reference to Divinity is a signal of deception.

Roseboro felt the need to ingratiate himself with the 911 operator calling him “sir” four times and using the word “please” twice.

Here an excerpt of that incriminating emergency call:

Operator: Okay, is that the siren from the fire department there?

Michael Roseboro: Yes.

Operator: OKay.

Michael Roseboro: Hold on, I have to throw up, please, hold on.

Operator: Okay.

Michael Roseboro: I’m sorry.

Jan Roseboro die in the hospital less than an hour after Michael Roseboro called 911.

Detectives noticed that Micheal Roseboro did not seem concerned with his wife’s condition and had 3 minor scratches on his face.

Jan’s death was classified as a homicide by Dr. Ross, the Coroner who performed the autopsy. “There were bruises basically to the back of the neck. I said, ‘Oh, my goodness. We have strangulation here. But we have a very particular type of strangulation. And the bruises are the in the back, almost as if it were hidden. That told me that she had been beaten. She had been bludgeoned. And she’d been hit about her head numerous times. Numerous times. The cause of death was multiple traumatic injuries. And that was a combination of strangulation, blunt-force trauma to the head, as well as drowning. It was only after I’d done the complete internal examination I was convinced this was a homicide”, Dr. Ross said to 48 Hours.

Jan had been beaten with a blunt object in the back of her head, choked and then placed into the swimming pool while still alive.

Michael’s DNA was found under Jan’s fingernails.

One of the neighbors told investigators that on July 22, 2008 around 10:30, she heard female screams.

Detectives learned that Michael was a serial cheater and that his current mistress, Angela Funk, 38, a married woman who lived near the Roseboro Denver funeral home, was pregnant with his child.

On August 2, 2008 Michael Roseboro was arrested and charged with the first-degree murder of his wife.

On July 30, 2009, after two weeks of testimony, a Lancaster County jury found Michael Roseboro guilty of first-degree murder in the death of his wife Jan.

After the verdict, the District Attorney Craig Stedman said: “When you looked at the evidence in its totality, it was an overwhelming case that he had brutally murdered his wife for his own selfish greed, purposes and out of a twisted obsession for a mistress who he wanted to be with”.

Weeks after the verdict, Michael Roseboro released this statement to 48 Hours:

We look for him to say “I didn’t kill my wife Jan”.

“My name is Michael Roseboro. I’ve been accused of killing my wife, Jan, who I’ve been married to for 19 years. I did not and I would never kill my wife. I had nothing to do with her murder, and I miss her very much”.

“I did not” is an unreliable denial, he violated component three of a reliable denial.

“I would never kill my wife” is an unreliable denial, he substitutes “didn’t” with  “would never” violating component two of a reliable denial.

“I had nothing to do with her murder” is an unreliable denial.

On September 25, 2009 Judge James Cullen imposed to Michael Roseboro the mandatory life sentence.


Salvatore Parolisi

Ascoli, Italia.

On April 18, 2011, at 16.34 p.m. the owner of a restaurant made an emergency call from the cell phone of Corporal Salvatore Parolisi to report Parolisi’s wife, Melania Rea, 29, missing.

Melania Rea

In the afternoon of April 18, 2011, Corporal Salvatore Parolisi told the owner of the restaurant “Il Cacciatore”, Giovanna Flamini, that his wife was missing, after a few minutes search, he asked Mrs Flamini to speak with the 112 operator through his cell phone because he was too frantic to call, he then went to the bathroom to throw up.

Giovanna Flamini was unable to give the operator all the information he needs, therefore, after 2 minutes and 43 seconds, she invites Parolisi to speak with the 112. During the phone call Parolisi sounded deceptive, spoke at the past of his wife and appeared prematurely frantic and unable to concentrate.

A friend of Parolisi and co-worker, Raffaele Paciolla, who was with him in the early stage of the research of his wife told investigators that Salvatore was inexplicably frantic, unable to speak without gasping and that he kept burping.

Those were symptoms of the General Adaptation Syndrome. Parolisi had killed his wife Melania by stabbing her 35 times and he was unable to control the stress due to his fear of being caught.
