The death of a 41-year-old Armstrong County man found in a bathroom at Butler Memorial Hospital last weekend is being investigated as a possible heroin overdose, authorities said.

Brent A. Lindsay of Worthington was found late Friday night unresponsive on the bathroom floor, Butler police said.

Sources told the Butler Eagle that drug paraphernalia and three empty stamp bags of suspected heroin were on the floor.

However, police would not confirm what evidence if any was collected.

An autopsy was not conducted but investigators are awaiting results of lab work.

A toxicology test should determine any link between the death and a lethal batch of fentanyl-laced heroin that started sweeping through Western Pennsylvania last month.

The tainted heroin is believed to be responsible for about two dozen drug-related deaths in Allegheny, Butler, Armstrong, Beaver and Westmoreland counties.

State, county and local law enforcement officials say the deadly heroin mix has been placed in bags stamped with the words Theraflu, Bud Ice and Income Tax.

None of the bags found in the hospital bathroom were marked with those street names, sources said.

Police were initially notified by the hospital at 10:44 p.m. Friday.

“We were told that a male was unconscious on the floor,” said police Capt. David Dalcamo, “and that CPR had started and was in progress.”

It was not known how long Linsday was in the bathroom, who found him or why he went to the hospital.

Connie Downs, a hospital spokesman, said because there is a continuing investigation the hospital would have no comment on the death.

Police said they are investigating why he was at the hospital. But Dalcamo is providing few details about the case or the investigation.

“We’re investigating the cause of death,” Dalcamo said Wednesday. “We’re working with other agencies.”

Among those other agencies is the Butler County Coroner’s Office. But office secretary Patricia Blanchard said Coroner William Young III had no comment.

“Bill doesn’t want any information released,” the secretary said.

Police that night contacted prosecutor Ben Simon, who was serving as the on-call Butler County assistant district attorney. He told police an autopsy was not necessary because there was no apparent foul play.

Simon said toxicology tests should be sufficient to help determine the exact cause of death. Those tests should take a month or longer.
