Tracy Marie Kroh was seventeen years old, a member of the National Honor Society at Halifax High School in Dauphin County, Pennsylvania, described by her own school principal as an extremely responsible student. She drew for the school newspaper, served as yearbook editor, and belonged to Future Business Leaders of America, a genuinely engaged, high achieving teenager heading into what she was excited to begin as her senior year. On the evening of August 5, 1989, around ten o'clock, Tracy drove her white 1971 Mercury Comet, marked with a distinctive blue stripe, to the Alex Acres Trailer Park to visit her older sister and brother-in-law. They were not home. Tracy left a barbecue grill and some grocery store coupons on their front steps and got back in her car. She never made it back to her own family's home in Millersburg.

A Car Emptied of Everything

Tracy's parents did not initially panic when she failed to come home that night, assuming, reasonably enough given her habits, that she had simply decided to stay overnight at her sister's, something she had done many times before without incident. It was only the next day, once they learned directly from her sister that Tracy had never actually arrived or stayed the night, that they realized something was genuinely wrong and contacted police. That same evening, August 6, Tracy's car turned up parked at the town square in Millersburg, several miles from where she had last been seen. Her personal belongings were gone from inside it entirely.

What made the disappearance especially unsettling to investigators from the outset was what Tracy had left behind rather than what was missing. She had three hundred dollars in cash sitting in her own bedroom back home, along with another four hundred dollars still sitting untouched in her bank account, money any teenager planning to run away or start a new life elsewhere would have had every reason to take with her. She had no documented history of running away, no known conflict at home, and by every account from people who knew her, a level of enthusiasm about her upcoming senior year that made any theory of voluntary disappearance difficult to sustain.

A Wallet in a Creek, Four Years Later

The case went cold for years without producing a single significant break. Then, in December 1993, more than four years after Tracy vanished, a farmer discovered fragments of a wallet along Wiconisco Creek in Washington Township, roughly nine miles from Millersburg. Investigators confirmed the fragments included Tracy's driver's license and her National Honor Society membership card. Despite extensive searching of the area surrounding the creek, no further physical evidence, and no remains, were ever recovered.

A Boyfriend, a Witness, and a Perjury Charge

The investigation eventually developed real suspicion around Matthew Webster, identified as Tracy's boyfriend at the time she disappeared, whose parents lived near the town square where her car was found abandoned. In 2016, a woman named Holly Mallett came forward and told investigators that Webster had once confided in her directly about what happened to Tracy, allegedly telling her it was supposed to be just a rape and done, but then it turned into something else entirely, an account implying he had witnessed or participated in an assault that escalated into her death. When Webster was brought before a grand jury and questioned about that conversation, he denied it had ever taken place.

That denial eventually produced criminal consequences of its own, though not for Tracy's disappearance directly. In 2019, Webster pleaded no contest to felony perjury connected to his grand jury testimony and was sentenced to six months, a term he served entirely as time already credited and was released immediately upon sentencing. Holly Mallett herself was separately charged with felony perjury in 2020 and received a considerably longer sentence of twenty three months, suggesting investigators ultimately found problems with her own account as well as his. Neither Webster nor Mallett was ever charged in direct connection with what actually happened to Tracy.

The Family Friend Everyone Trusted

The investigation's most significant break came from an entirely different direction, a man named Mark Eugene Warfel, who had run a local auto repair shop where Tracy's own father worked, and who had spent years as a close, trusted friend of the Kroh family, known for showering Tracy and her sisters with attention and gifts throughout the 1980s. What nobody in the family realized at the time was that Warfel had been carrying on a secret affair with Tracy's own mother, a relationship that produced a child, making Warfel the secret biological father of one of Tracy's own younger sisters, a fact that did not come to public light until 2019, thirty years after Tracy disappeared.

Warfel was formally named a suspect in Tracy's case in May 2022, identified during a competency hearing connected to separate, unrelated burglary charges he was already facing at the time. Investigators have also named him a suspect in the death of his own wife and in multiple sexual assaults against other women, painting a picture of a man capable of considerably more than the trusted family friend persona he maintained around the Krohs for years. During a hospital visit that Tracy's sister Kim secretly recorded, Warfel reportedly offered his own account of what had happened to Tracy, claiming a man nicknamed Big Goofus had talked Tracy into letting him drive her car before strangling her, and that Warfel believed her body had ultimately been placed in a mine shaft near Loyalton, with Goofus supposedly keeping some of her clothing afterward. Prosecutors reportedly described some of what Warfel said during that recorded conversation as very significant, even as a judge ultimately determined he was not competent to stand trial due to his own medical condition. Warfel has consistently maintained his innocence.

A Case That Tore Down a House Without Finding an Answer

As investigators pursued the leads connected to Warfel, Pennsylvania State Police conducted an extensive search of his property, a process that at one point included the physical demolition of structures on his land in the search for any remaining physical evidence connected to Tracy. Despite that level of effort, no confirmed remains or conclusive new evidence have been publicly reported as recovered from the site.

Still Unsolved, Still Actively Investigated

More than three and a half decades after Tracy Marie Kroh dropped off a grill and some coupons on her sister's front steps, her case remains open and, by Pennsylvania State Police's own account, still actively worked. A five thousand dollar reward remains available for information leading to her recovery. What the investigation has produced over the years, a perjury conviction unrelated to the actual crime, a named suspect too medically compromised to stand trial, a recorded hospital confession pointing toward a third party investigators have never identified by his real name, and a demolished house that yielded no remains, reflects just how thoroughly a single missing teenager's case can expand outward into an entire web of secrets, betrayals, and half answers without ever producing the one thing her family has waited more than thirty years to actually receive.
