Army Spouse Diane Pelkey Reported Missing; Fort Carson Soldier Michael Pelkey Convicted of Murder at Court Martial, Sentenced to Life in Prison (October 8, 1993)

When the severed head of a wife and mother is found, Lt. Joe Kenda uses forensics and interrogation to find both her body and her killer. Then… a young man’s murder looks like a robbery gone wrong until Kenda learns the odd reason he’s living there. -The Line Goes Dead, Homicide Hunter (S6,E13)

On October 16, 1993, a mother was home with her son cooking supper. She went outside to call her dog Shadow to return home. When the dog returned, he had something large in his mouth. Danielle and her son realized that the dog had a human skull in it’s mouth. Lt. Joe Kenda of the Colorado Spring Police Department was grocery shopping when he got the call. He left his grocery shopping cart as is and headed to the scene. When Kenda arrived on the scene, the medical examiner was observing the skull. The medical examiner observed another animal got to the skull before the dog did and the time of death was within the last couple of weeks. The skull appeared to be a female with no obvious signs of bullet wounds or trauma. But they didn’t have the rest of the body to determine the official cause of death. Lt. Joe Kenda decided to start with the missing persons reports first.

Kenda also wanted to find the rest of the remains. Unfortunately, it was dark outside so they decided to resume the search the next day in during the daylight hours. The police used cadaver dogs to find the rest of the body. Cadaver dogs are trained to notify their handler when they make a hit. Kenda knew this would be a daunting task because El Paso County is the size of Rhode Island. An hour into the search, the K9 officer got a hit. They found a few more human bones; some still had flesh attached and some had teeth marks on them. Kenda theorized maybe she was a hiker out for a walk one day and got attacked by a bear. Now Joe Kenda needed to identify the dead female. They used dental records to determine if the dead woman’s teeth matched any dental records on file. On the third missing woman’s dental records, they finally found a match. Diane Pelkey, 36, was reported missing one week prior by her husband Michael Pelkey.

Michael Pelkey paid for a full page ad in the newspaper looking for Diane Pelkey. Police learned Michael was a 16 year veteran in the US Army and lived off post in Colorado Springs with his wife. Kenda now had the unfortunate task of informing Michael Pelkey of his wife’s death. He told him positive identification was made through dental records. Michael Pelkey was overcome with grief. They had been together for over 15 years. They had a son and she was four months pregnant.  Michael claims the last time he saw Diane they were out at dinner and then got in an argument. He said she walked away from him and he had not seen her since. Kenda deduced she would have had to walk ten miles to get home. Kenda decided she was not killed by a bear, she was killed by a human. They didn’t know if maybe someone picked her up hitchhiking and killed her. Michael Pelkey claimed he didn’t look for his wife because he had to go home and take care of their five year old son.

As Kenda was reviewing the missing persons report for Diane Pelkey, he noticed one of the officers put JDLR (Just Doesn’t Look Right) on the bottom of the report. This is usually done when an officer feels something isn’t right or the person making the report was suspicious. Kenda spoke with the officer who took the report. They both decided the missing persons report was suspicious because Michael didn’t say anything about their child, Diane’s pregnancy, or that they got in an argument that same night. Kenda explained that usually if someone thinks something happen to a loved one, they won’t leave him alone. Kenda ran Michael Pelkey’s name through the data base and found there was a history of domestic violence, restraining orders in the past, and the couple had filed for a divorce. Kenda believed Michael Pelkey may have killed his wife but he wasn’t sure he had the authority to pursue the case.

Diane Pelkey’s remains were found in El Paso County, Colorado so the case may be out of Kenda’s jurisdiction. He pressed the sheriff’s office to put the squeeze on Michael Pelkey. They brought him into the sheriff’s department and started questioning him. They presented all the evidence they had to Pelkey and he became overwhelmed. Michael broke during the interrogation and admitted to killing his wife on October 8, 1993. He claimed they were in the car and he wanted to do some fishing. They started arguing; he accused her of being unfaithful, she accused him of being unfaithful. He said she wanted out of the vehicle to get some space from him and that didn’t sit well with him. Michael claims he snapped and started strangling Diane. Michael tried to claim that it was an accident. Kenda thought this was not an accident because it takes two to three minutes to strangle someone to death.

Michael Pelkey then told detectives he panicked after strangling Diane and decided to drive to a rural area in the Rocky Mountain foothills to dispose of her body. He put a seatbelt on her and drove as if she was simply a passenger in his car. He drove to a ravine near the highway and left her in an area where he didn’t think anyone would find her. Afterwards, he filed a missing persons report and took out an ad in the local paper to deflect suspicion from himself. Michael Pelkey probably thought he would get away with murdering her wife. But his plan unraveled and he was arrested for murder. The District Attorney allowed the Fort Carson Army leadership to court martial him despite the fact that the crime occurred in El Paso County. Michael Pelkey was convicted of second degree murder and sentenced to life. He is serving his sentence at Fort Leavenworth, a military penitentiary in Kansas.

You are held to a higher standard in the United States military. You will not behave in this way and if you do, you will be one sorry son of a bitch. Sgt. Pelkey found that out the hard way. -Lt. Joe Kenda

Phonthip Ott Discovered Dead in California River; Spouse Dennis Ott, US Coast Guard, Convicted of Murder and Sentenced to Life in Prison (May 17, 1992)

Phonthip (Boonack) Ott, 33, disappeared from her home in California on May 17, 1992. A couple months later, Phonthip Ott’s dead body was discovered in the Sacramento River near Sacramento. Phonthips body was stuffed in a large nylon duffle bag about 5 feet tall. It was held down with H-shaped cement anchors. The day their mother disappeared, Phonthip’s daughters, Tippy Dhaliwal, 14, and Jeanette Marine, 10, spent the day with their grandparents. Upon their return home, the two girls sensed something was wrong when their mother wasn’t home and immediately suspected their stepfather of killing her. Dennis Ott was an active duty petty officer in the U.S. Coast Guard and his relationship with Phonthip was tumultuous. There was interpersonal violence and adultery on both sides but it appears the domestic violence escalated with Dennis; he was jealous and possessive of Phonthip and didn’t like that she was having affairs. At one point in the relationship, Dennis threatened her life and this is when Phonthip decided to file for a restraining order and a divorce. It would be this same day, May 17th, that Phonthip would disappear.

At first, it appeared Dennis Ott was not going to be held accountable as he continued to go to work at the Coast Guard station day after day. Then one day, a 16 year old Tippy, wrote a letter to the district attorney and the Coast Guard about her mother’s case. It would be this letter that reinvigorated interest in the homicide case and after further investigation, Ott was arrested in November 1994. The duffel bag found at the crime scene was issued to Coast Guard personnel only. The H-shaped cement anchors at the crime scene matched those found in Ott’s backyard. And there appeared to be a history of escalating domestic violence that ended in murder because Phonthip wanted to leave him (rejection). In 1995, Dennis Ott was convicted and sentenced to life in prison with the possibility of parole. The two sisters hope Dennis Ott remains in prison for the rest of his life and plan to attend all the parole hearings in the future. After 20 years in prison, Dennis was eligible for parole in California. His first parole hearing was denied because the parole board felt he was too evasive and wouldn’t admit culpability.

Dennis Ott has always maintained his innocence and continues to say he did not kill his wife. Dennis Ott is up for a parole hearing again in October 2017, only two years after his last parole hearing. Both sisters share that every parole hearing re-victimizes them because they have to re-live the traumatic events of the day they lost their mother.

Military Spouse Julie Snodgrass Found Stabbed to Death in the Philippines; Air Force Sgt. Joseph Snodgrass Sentenced to Life in Prison (February 26, 1991)

Military spouse Julie Snodgrass, 33, was found stabbed to death near Clark Air Force Base in the Philippines on February 26, 1991. Julie was discovered in the cab of her pickup truck on an isolated road off base and an autopsy revealed that she was stabbed more than 42 times. The Air Force Office of Special Investigations (AFOSI) had jurisdiction of the case. During the investigation, they found evidence on Air Force Sgt. Joseph Snodgrass’ work computer that linked him to the crime. AFOSI found a letter addressed to his mistress asking for help with the murder of his wife. He also talked about the life insurance policy he had purchased in the event his wife died. The letter disclosed that Snodgrass elicited the help of his housekeeper (and lover), a Philippine native, to hire three hitmen to carry out the crime. The pair could then be together and live off the $400,000 life insurance pay out. During an interview with AFOSI, Sgt. Snodgrass grabbed the floppy disks and cut them to pieces with some shears.

Computer forensic scientists were able to find a way to put the disks back together so the data was readable again. This was the evidence the Air Force needed to make their murder-for-hire case. In the meantime in June 1991, Mount Pinatubo erupted resulting in layers of volcanic ash falling on Clark Air Force Base and Naval Base Subic Bay. Amidst the chaos, Snodgrass attempted a jail break in August 1991 while awaiting trial but lost his bearings in the ashy mess and eventually surrendered. The eruption’s aftermath triggered the decision to withdraw all American Forces from the Philippines. Joseph Snodgrass pleaded guilty to the solicitation of his wife’s murder and was sentenced to life with no parole in a military prison. As a result of the forensic history made by piecing the floppy disk back together making it usable again, the military changed the policies pertaining to the destruction of classified data on floppy disks. The AFOSI’s “catastrophic blunder” was made right and secure communications destruction policy was changed as a result of the lessons learned when forensic scientists made history.

Medical Detectives (Forensic Files) – Season 10, Ep 9: Shear Luck

When the wife of a serviceman was brutally murdered in the Philippines, the Air Force Office of Special Investigators swung into action. Clues led to the victim’s husband, but he insisted he was innocent. Investigators would have to do something unprecedented: Reassemble a 5 1/4 inch computer disk which had been cut to pieces with pinking shears. -Shear Luck, Forensic Files (S10,E9)

Update (April 11, 2021:

Today, we were informed that Forensic Files got the narrative wrong and Air Force OSI did not commit a “catastrophic blunder.” MJFA reminded said person that if they weren’t hiding all the crime and death from the public, we’d know more about the case details. We simply are repeating what the crew at Forensic Files said. First this person reminded us, the floppy disk was destroyed in their presence because according to Forensic Files, they were “momentarily distracted.” Then they failed to address the fact an accused killer had a pair of scissors on his person, both a danger to OSI and other Air Force personnel. And finally, Joe Snodgrass worked with AFOSI and knew prior to his interview he was going to be questioned about the floppy disks, so he came prepared to destroy them.
