Hearing Postponed for Man Facing Drug Charges after Party at Treesdale House

Tyler McWilliams' preliminary hearing will be held June 20.

The preliminary hearing for a 20-year-old facing drug and underage drinking charges related to a party at a Treesdale home was postponed Wednesday.

Tyler Joseph McWilliams' hearing was rescheduled to June 20 before Magisterial District Judge William K. Wagner.

McWilliams, who turned 20 on April 27, is charged with two felony counts—for the delivery and sale of marijuana in addition to possession with intent to deliver. He also is facing three drug-related misdemeanors and a summary offense of underage drinking, according to court documents.

An investigation was triggered when Northern Regional police were called to the Treesdale house owned by model Theresa Gaugler about 1 a.m. Saturday, April 28, for an underage drinking party in the 2000 block of Condor Lane, according to police.

Gaugler was not home at the time of the party. She said McWilliams is a friend of her children who was allowed to live in their basement for free.

McWilliams was arraigned over the weekend and released on his own recognizance, according to court documents.

On the night of the party, he was sent to the hospital by ambulance when police found him unresponsive in the house’s game room, police said. 

McWilliams was taken to UPMC Passavant where tests showed he had a blood alcohol content, commonly referred to as a BAC, of .366 percent, according to the criminal complaint. 

Upon checking the rest of the house to see if other party-goers were in the same condition, officers saw what appeared to be a clandestine lab that could involve drugs or explosives, police said.

The FBIPennsylvania State Police and federal Bureau of Alcohol, Tobacco, Firearms and Explosives were called in Saturday, April 28, to investigate at the home. Police also summoned the Allegheny County Bomb Squad and a county Hazmat team.

Police are awaiting lab results to see if other charges will be filed.
