A Franklin Township man is headed to court on charges related to the alleged fatal stabbing of a mental health group home employee on Christmas Eve 2020.

The case moved out of a district court late last month, almost two years to the day after he was charged.

Investigators allege Patrick Guyer, 26, killed Arthur Stanley, of Penn Township, after breaking into the staff office at a TrueNorth Wellness Services group home in the 300 block of High Street in Hanover during the early-morning hours of Dec. 24, 2020.

The attack came as Guyer made accusations that staff at the home bullied him when he was a resident and that one worker sexually abused his ex-girlfriend, according to police.

A witness told Hanover Borough Police they saw a car similar to the type Guyer drove parked near the facility.

The witness then heard a woman scream. When they went to check on the noise, they found that the staff office door had been forced open and saw a gun on a door mat, police said in charging documents.

Guyer allegedly chased the 59-year-old Stanley in the room with a kitchen knife before stabbing him multiple times and killing him, according to investigators.

When police interviewed Guyer, he allegedly stated he would’ve killed any staff member he found in the office that morning, even if multiple people had been there. He allegedly told police where to find the knife, and they located what was reported to be a blood-covered knife in the basement of his Franklin Township home, according to the documents.

Guyer allegedly said he was driven to commit the act because staff bullied him when he was a past resident of the group home, police said.

Investigators learned he filed a report that Dec. 16, about a week before the stabbing, where he accused a facility employee of sexually abusing his ex-girlfriend while she resided at the home. The two apparently broke up over the situation, according to charging documents.

Then on Dec. 19, police said Guyer called the woman and left a voicemail where he allegedly threatened to stab her.

Guyer was charged with criminal homicide and a felony count of burglary. He was taken into custody that Christmas without bail, according to court information.

Since then, his preliminary hearing in the district court in Hanover has been postponed six times through 2021 and 2022, until it was held Dec. 20, court records show.
