The commander of Pennsylvania's Region 4 Emergency Medical Services Strike Team who is also an assistant fire chief in Leetsdale has been ordered to stand trial in connection with a year-old rape charge filed by a Bucks County woman.

Amos P. Cameron, 47, of Leetsdale, on July 22 was arrested and arraigned on charges of rape of an unconscious victim, sexual assault and indecent assault of an unconscious or unaware victim.

On the same day, he requested and was granted a preliminary hearing in Harrisburg before District Judge Gregory Johnson, who ordered the trial and set bail at $200,000.

The bond immediately was posted, and Mr. Cameron is free. He is scheduled for formal arraignment on the charges Oct. 1 in Dauphin County Common Pleas Court.

Since the incident, which was reported last Aug. 12 by the 45-year-old woman, Mr. Cameron has been interviewed twice by state police investigators in Harrisburg and Pittsburgh.

Each time he denied that he raped the woman. He contends their sexual encounter on the night of Aug. 11 and into the morning of Aug. 12 was consensual.

The woman had been a speaker at an EMS conference Aug. 11 at a hotel in Harrisburg.

After the event, she had dinner and drinks with colleagues at the hotel. She became ill and headed to her hotel room, according to a police affidavit that supports the fire official's arrest.

On the way, she said she spoke briefly with a group that included Mr. Cameron, who offered to accompany her to the floor where both had rooms reserved.

She knows Mr. Cameron from past conferences they had attended, police said.

The woman said Mr. Cameron followed her into her room as she rushed inside to vomit into a trash can.

One of the last things she remembered was her alleged attacker giving her something to drink before she passed out.

She awakened briefly to find Mr. Cameron was on top of her having sex. She said she tried to stop him, but she "went blank" again, the affidavit said.

She woke up again around 5:30 a.m. naked in her bed, covered with sheets that were blood-stained. Her underwear also was stained with blood, the affidavit said.

Her clothing had been neatly folded and placed on a table nearby.

As her memory returned, the woman said she drove herself to the Hershey Medical Center, where she was examined and treated.

On Aug. 15, last year, the incident was reported to state police.

The Emergency Medical Services Institute is the Regional EMS Council, headquartered in Wilkinsburg under the auspices of the state Department of Health.

The EMSI covers a 10-county region that includes Allegheny, Armstrong, Beaver, Butler, Fayette, Greene, Indiana, Lawrence, Washington and Westmoreland counties.

On the agency's Web site, Mr. Cameron is listed as regional operations coordinator for EMSI, overseeing inspections of ambulance companies.
