Two Cases of Missing Mothers, and One Suspect


It was January 2, 2009 when Shon Pernice was scheduled to attend a training session with the Missouri National Guard. Instead he picks up his kids at a neighbors home and his wife, Renee, is not there. That evening his daughter from another relationship was concerned she had not heard from Renee, her step-mother. Around 9:30 pm the child calls Renee, leaving a voice mail asking her to come home.

Saturday, January 3, at approximately 4:30 a.m., leaving his 11,- 8-, and 6-year-old children alone while they were sleeping, Shon Pernice goes to a fire station. He used his key card to enter Fire Station No. 5’s hazmat storage area. This area stores chemicals used for clean-up of hazardous spills. Shon is an EMT for the Independence, Missouri, fire department assigned to Fire Station No. 7, not station No. 5–a huge red flag.

He does not report to the National Guard that weekend. He goes into a facility likely forgetting or not knowing that his key card will be documented and recorded upon entry. His story is fabricated. He is the last person to see her alive. He does not report Renee missing. He has a lot to lose financially.

On Saturday, January 3, the stepchild calls her mother. According to accounts, the child is scared, so her mother picks up the daughter at the Pernice home, cutting short the normal visit. She then contacts someone from Renee’s family. A few hours later a family member calls the Pernice home to speak to Renee. Shon answered and said that he did not know where Renee was. Family members called 911.

Shon Pernice has given conflicting information on when he last saw Renee. He told a family member it was on January 1. He told police it was on the morning of January 2 between 9 and 10 a.m. At approximately 3 p.m., family members met officers at Renee’s home. Family members, along with officers, entered the residence and discovered that no one was home. They also discovered that Renee’s purse, vehicle, personal hygiene items and coat were at the residence. They noticed that Renee’s wallet, credit cards and cell phone were missing. Renee’s car was parked in the garage.

At the Pernice residence a call came in to a family member from Renee’s cell phone at approximately 4 pm. A homeless man had found the phone at about 1 a.m. on the morning of January 3, 2009, on the ground in the northeast part of town, approximately 12 miles from Renee’s home. Police sent a patrolman to pick up Renee’s phone from the homeless person.

The family members, not Shon Pernice, filed a missing person report while at the residence with police.

Another red flag, and important pattern of conduct by the last person to see his wife alive, Shon Pernice and  two attorneys arrived at the home and ordered the family and police to leave. The attorneys stated Pernice would not be speaking to family members or the police except through them.

On Sunday, January 4, Renee’s family immediately printed up posters and began posting flyers. They also searched portions of Kessler Park close to where Renee’s cell phone was found. In addition, the family contacted the local news stations asking if they would broadcast the news of Renee’s disappearance.

Monday, January 5, Detectives found divorce documents at Renee’s place of employment. They also found a photo of Shon with one of the children and an unknown woman in the file.

Tuesday, January 6, in the evening, Shon drove to Line Creek Park, approximately 1.5 miles from Renee’s house and let the family dog out of the van and left. Detectives who were observing Shon retrieved the dog. On January 7, police to obtain a warrant to search Renee’s house and they obtained another warrant on January 9 for the car.

A little over two years since Renee Pernice vanished, her remains have yet to be recovered. Had the stepchild not been alarmed and contacted her mother, a lot more evidence would have likely vanished.

In May of 2010, without a body, Shon Pernice was charged with murder and is being held on a million dollar bond. He is scheduled for trial in June of 2011. What is disturbing is that Renee may never be located because of the chemicals, in my opinion, used when he killed her. The timeline of when the children went to bed and when Pernice left the residence is important because that is when he may have disposed of her body. Where he had it hidden is anyone's guess, but it had to be a safe enough place for him to return, a place only he knew, where no one would suspect.

The details a week prior are also important to the case, including cell phone records, purchases at hardware stores, his timecards at work, the strange woman in a photo with him and the kids. His fire work boots and, frankly, any shoes in his truck, locker at work, the house and on the property are important evidence along with credit card activity six months prior. If they can identify the woman from the photo, her cell phone records and credit card activity should also be considered, as this is someone who might unknowingly make purchases for him, or secure a cell phone and have packages delivered to her.

The pattern of conduct of Renee Pernice leading up to the day she vanished could be like so many other women trying to leave a marriage. Renee held a good job with a salary large enough to support herself and her children. In fact, Renee alone cared for her children while her husband was stationed overseas. During the investigation, divorce papers were discovered in Renee's home office, leading us to believe she was serious this time about leaving her marriage.

Renee Pernice was close to her family, was in constant contact, and as is often heard in cases of missing mothers, "She would never leave her children." Most of the statements from Shon Pernice are in direct contrast with the woman and mother her family knew her to be. Perhaps Renée confided in her family or close friends about the upcoming divorce, or about the problems in her marriage leading her to make the decision to finalize the divorce.

Tragically, this case is one of thousands, when a person begins a divorce action, separates or ends a relationship, that having the Evidentiary Abuse Affidavit (as provided in the book Time's Up) and video prepared, with copies given to trusted friends and relatives, removes the burden by surviving families members to have cases of intimate partner homicide investigated and those responsible arrested.

A $25,000 reward has been offered for information that leads to where her remains. The family is trying to appeal to the people that know, or have heard things on the fringes and could give them a tip. That's all they're asking for, according to Renee's father, Rick Pretz.

Anyone with information on Renee Pernice's disappearance is asked to call the TIPS Hotline at 816-474-TIPS.

Shon Pernice is also linked to another missing mother, Star Boomer. In my opinion, he can be placed at her crime scene according to eye witnesses years earlier. Star Boomer has been missing since 1999, and she left behind a son and a family who deserve some real, truthful answers. Shon Pernice was the last person known to see both women.

There is a $5,000 reward for information in Star Boomer's case. Call the TIPS Hotline or link to the family's private investigator's website for the case. Those with information about the disappearance of Star Boomer are asked to contact the KBI at (800)-KS-CRIME

Toxicology: Poison, Drugs, and Chemicals

by Andrea Campbell

Q: Can you tell me more about toxicology and what a forensic toxicologist is all about?

A: The busiest department in a crime lab, hands down, has to be forensic toxicology. This science is essentially a specialty area of analytical chemistry, so think vials, jars, and lots of machinery to test them when you consider this area's discipline.

Toxicology, per se, is the science of adverse effects of chemicals, either natural or man-made, on living organisms. The job of a toxicologist is to detect and identify foreign chemicals in the body, with a particular emphasis on toxic or hazardous substances. There are several sub-groups of toxicology expert: a descriptive toxicologist performs toxicity tests to evaluate the risk that exposure poses to humans; a mechanistic toxicologist attempts to determine how substances exert deleterious effects on living organisms; and the regulatory toxicologist judges whether or not a substance has low enough risk to justify making it available to the public.

Toxins then, are materials that threaten the life of living things. Poisons are a subgroup of toxins. Toxic materials can come in many forms such as gas, liquids, solids, animal, mineral and vegetable. Toxins can be ingested, inhaled or absorbed through the skin and organs. Some toxins have medicinal value and, if this is the case, the amount that is taken is significant to health, but—if abused, may cause irreparable damage. Toxins may have antidotes, but some do not.

Some toxins may disguise or mask themselves, whereas some are identifiable by their symptoms. Here are a couple of examples of toxins and their symptoms:

Acids (nitric, hydrochloric, sulfuric) = Burns around mouth, lips, nose
Aniline (hypnotics, nitrobenzene) = Skin of face and neck quite dark
Atropine (Belladonna, Scopolamine) = Pupil of eye dilated
Arsenic (metals, mercury, copper, etc.) = Severe, unexplained diarrhea
Carbon Monoxide = Skin is bright cherry red
Cyanide = Quick death, red skin, odor of peach
Nicotine = Convulsion
Opiates = Pupil of eye contracted
And so forth.

The true incidence of poisoning in the United States is unknown. Approximately 2 million cases are voluntarily reported to poison control centers each year, and officially, a rather steady figure of about 700 deaths by poisoning is reported each year. Children under age 6 account for the majority of poisonings reported, but adults account for the majority of deaths by poisoning, most of which is intentional rather than accidental.

Some common reported poisons are: household cleaning supplies, antidepressant medications, analgesics (aspirin, acetaminophen), street drugs, cough and cold remedies, cardiovascular drugs, plants, alcohol, gases and fumes, pesticides, asthma therapies, industrial chemicals, sedatives, food poisoning, insects and other animals.

It is not easy to distinguish toxic from nontoxic substances. A key principle in toxicology is the dose-response relationship. The toxic effects of substances are not side effects. "Side effects" are defined as non-deleterious, such as dry mouth, for example. Toxic effects are the undesirable results of a direct effect, like the result of too much stress on the body; in other words, the body is upset by physical, chemical or biological agents and it manifests itself as a reaction. Toxic reactions are classified as one of three reactions: pharmacological—with injury to the central nervous system; pathological—with injury to the liver; and genotoxic—causing the creation of benign or malignant neoplasms or tumors.

For certification as a toxicologist, an individual must possess a Ph.D. or doctorate in one of the natural sciences. Undergraduate degrees must also be in either biology or chemistry, usually. Certification is bestowed by the American Board of Forensic Toxicology and the expert may use the title of “Diplomate,” which must be renewed every three years. Board-certified toxicologists will never face difficulties qualifying as an expert witness. State crime laboratories may not have a toxicologist on staff, their functions being performed by a criminalist, a biochemist, a forensic biologist or other technician. These personnel would typically have a Bachelor’s or Master’s degree in any of the sciences.

A forensic toxicologist is normally presented with preserved samples of body fluids, stomach contents, and organ parts. They will have access to the coroner’s report which should contain information on various signs and symptoms as well as other postmortem data. The toxicologist needs a thorough knowledge of how the body alters or metabolizes drugs because few substances leave the body in the same state as when they entered.

Hooray for toxicologists, an overworked group and a much needed discipline in the realm of forensic science.
