Dateline: The Premonition is an episode that follows the story of John Yelenic, a well-known dentist from Blairsville, Pennsylvania, who was well-liked by his community. But for some reason, he had an overwhelming fear that something terrible was going to happen to him. As his attorney, Effie Alexander, told Dateline, Yelenic had confided in her that,“He was convinced that he was going to be killed and that his murder would be covered up and that the evidence would be buried along with him and that it would go unsolved.”He even gave her $10,000 in advance so a private investigator could be hired to look into his death if it ever happened. On April 13, 2006, his horrifying premonition came true. Yelenic, only 39 years old, was discovered violently murdered inside his home, which was later explored in Dateline: The Premonition, which revealed disturbing details about the case.Investigation and more details of Dateline: PremonitionJohn Yelenic’s death was one of the most brutal the community had ever seen. Early that morning, someone had entered his house and attacked him. His head was forced through a glass window by the front door, and his throat was cut. Dr. Cyril Wecht, who performed the autopsy, told Dateline it was,“certainly one of the most violent deaths I’ve seen.” View this post on Instagram Instagram PostAround 1:30 a.m., neighbors heard high-pitched screams but didn’t realize they were hearing a struggle that would end in someone's death. Later that day, 9-year-old neighbor Zachary Uss went to Yelenic’s home looking for his son, J.J., and instead found John's dead body. He told Dateline,“I noticed the broken glass on the steps… I put my hand through the window, I unlocked the door… and I saw John laying right there.”Officer Don Isherwood was one of the first on the scene and told Dateline,“It was pretty gruesome.”Blood was everywhere, and bloody footprints led away from the house. Yelenic’s divorce papers, scheduled to be finalized the next day, lay on a table, soaked in blood. Investigators began by looking at people who might have had conflicts with Yelenic. A neighbor said she heard someone yell“I’ll never loan you money again,” around the time of the murder. Yelenic often lent money to people, and detectives explored those connections, but those leads went nowhere.Attention then shifted to the intense and difficult divorce between Yelenic and his wife, Michele. She had moved on and was living with her boyfriend, Pennsylvania State Police Trooper Kevin Foley. Friends told investigators that the couple’s marriage had collapsed after both admitted to cheating. Michele had also accused Yelenic of abusing their son, but the court found no proof. At the time of Yelenic’s death, she was still listed as the beneficiary on his will and a $1 million life-insurance policy.Detective Janelle Lydic found the investigation challenging because Foley was someone she had worked with before and trusted. She told Dateline it was difficult to imagine a fellow officer could be involved. Still, she followed her instincts. Instead of immediately sending Yelenic’s fingernail clippings to the state lab, she saved them in a refrigerator at the station, a decision that later became crucial.About a year after the murder, Yelenic’s cousin, Mary Ann Clark, contacted the Pennsylvania Attorney General’s Office asking for help. Deputy Attorney General Anthony Krastek took over and was shocked to learn that neither Michele nor Foley had been interviewed. He also uncovered comments Foley reportedly made to coworkers, including statements like“I wish John Yelenic was dead”"I wish he died a horrible death.”Surveillance footage then surfaced showing a truck similar to Foley’s heading toward Yelenic’s house shortly before neighbors heard screams. The vehicle could not be positively identified, but it also could not be ruled out. When Lydic’s preserved fingernail samples were finally tested by the FBI, analysts found there was only a 1-in-13,000 chance the DNA under Yelenic’s nails belonged to anyone other than Foley. Later, advanced cyber-genetic testing determined it was 189 billion times more likely that the DNA was Foley’s.Investigators also discovered that the bloody footprints matched a rare type of Asics shoe. These shoes were not sold in the area, but records showed Foley had ordered the same model through a program available to law enforcement officers. Foley was arrested in 2007 and later convicted of first-degree murder. He received a life sentence. Michele was investigated as well, but no evidence was found that connected her to the crime. She later moved to Georgia with her children.Although justice was served, those close to Yelenic still carry the pain of losing him in such a violent way. As Dr. Maria Tacelosky told Dateline,“I don’t think you ever get over a murder… it’s always with you.”New Dateline episodes come out on Fridays at 10 pm ET.For more articles like this, follow Soap Central.
