A 21-year-old male Pitt student was pronounced dead Sunday morning at a South Oakland residence, according to the Allegheny County Medical Examiner’s Office.

Rick Lorah, a forensic supervisor for the office, said the student, Chase A. Longo, a mechanical engineering major, was pronounced dead at his Ward Street residence at 10:46 a.m.

Another supervisor at the medical examiner’s office said on Monday that the office would release the results of an autopsy it performed Monday morning after it completed a toxicology screening. The supervisor said toxicology screenings can take from 16 to 20 weeks to complete.

Loni Hardy-Mori, a Mount Washington resident who was on scene with police and investigators on Sunday, said she had met the student the night before at Rivers Casino.

The next morning, Hardy-Mori, 33, said she heard the student collapse in the kitchen at about 10 a.m. Sunday and attempted to perform CPR. The student had been foaming at the mouth, she said on Sunday.

City police are investigating.
