Man Arrested in Treesdale Investigation Had Extremely High Blood Alcohol Content, Court Documents Show

, they discovered a 20-year-old man who was "completely unresponsive" and called for an ambulance.

The Gibsonia resident also faces misdemeanor charges of possessing suspected marijuana and Metadate/Methylphenidate, the criminal complaint states.

His preliminary hearing is scheduled for Wednesday.

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. 

To compare, Pennsylvania DUI law refers to a BAC of .08 to .099 percent as general impairment; .10 to .159 percent as a high BAC, and .16 percent and above as the "highest BAC".

The Be Responsible About Drinking—B.R.A.D. 21—website states that a BAC of .35 percent is the equivalent to general anesthesia; at a .40 percent BAC reading, death is possible.

After finding McWilliams in such a serious state, police officers started checking the rest of the house in the 2000 block of Condor Lane to see if other party-goers were in the same condition, according to police.

They found what appeared to be a clandestine lab that could involve drugs or explosives, said police. The FBI, Pennsylvania State Police , federal Bureau of Alcohol, Tobacco, Firearms and Explosives, the Allegheny County Bomb Squad and a county Hazmat team were called in, police said.

Various items were taken from the house during that investigation and sent to a crime lab for analysis. More charges may be filed, depending on the outcome of the lab tests, police said.

McWilliams had been living in the basement of the home owned by model Theresa Gaugler for about three weeks, according to the criminal complaint. Gaugler told police McWilliams is a friend of her daughter, the complaint states.

Gaugler arrived at the house a short time after police and told them "she was unaware any such activity was taking place at her residence prior to her leaving," the criminal complaint reports.

When police first arrived at the house, a male under the age of 21 was seen running up the street from the Condor Lane house, police said. 

"This male was in possession of a suspected controlled substance and he had been drinking an alcoholic beverage while under the age of 21 years old," the criminal complaint states.

"Additional officers located two more males exiting the rear patio door of (the Condor Lane house) and both of these males were under 21 years of age and had been drinking alcohol" according to the complaint.

Before police went into the house, they stopped another party-goer who told them McWilliams sold him a gram of marijuana for $20, the complaint states.

Police noted the "extremely strong odor of marijuana throughout the residence and especially in the finished basement," the court documents state.

Gaugler gave them permission to search the basement, where they found a gallon-size Ziploc bag containing suspected marijuana and 19 packs of rolling papers, a marijuana grinder, five ceramic marijuana pipes with residue inside, a digital scale with marijuana residue, McWilliams' VISA check card and $370 in cash, court documents show.

Police also found "a black and white capsule labeled UCB 583 50mg which is a scheduled II controlled substance Metadate CD 50mg/methylphenidate," the complaint states, and an unlabeled pill bottle contained 70 square pink pills imprinted BD/10.
