A man accused of killing a Catholic deacon at a Long Island halfway house was ordered held without bail on Saturday for the slaying, which authorities believe may have been triggered by a squabble the two were having about his progress — at an anger management program at the facility.

Andre Patton, 47, faces a second-degree murder charge in the November stabbing death of Deacon Patrick Logsdon, 70, police said. He was nabbed Friday in Memphis and extradited to Nassau County, where he was arraigned at First District Court in Hempstead.

He could serve up to a life sentence in prison if convicted.

Patton was living at the Anthony House in Roosevelt on Nov. 3 when he allegedly knifed Logsdon, who was found unresponsive in a pool of blood with multiple stab wounds, before taking off.

Logsdon, who worked at the halfway house for more than 30 years, was pronounced dead at the scene.

Fitzpatrick said the deacon had “excessive” stab wounds – “over 20.”

Patton — who had just been released from a 30-day prison sentence for assault only days before the knifing — was in a rehabilitation program at the facility, possibly for anger management, Stephen Fitzpatrick, detective lieutenant of the Homicide Squad at the Nassau County Police Department, said at a Saturday press conference.

“Such programs were required for residents who had recently been released from prison, Fitzpatrick said.

“I think the dispute [with the deacon] was his [over] progress in the rehabilitation program,” he continued. “The deacon was questioning his progress and whatever he was telling him, I guess the deacon wasn’t accepting.”

Five days after the stabbing, Patton stole a Nassau Inter-County Express ride-along van that he ditched in Queens, Fitzpatrick said. It wasn’t clear how or why he ended up in Memphis.

Patton is from Ohio, where he was arrested for aggravated robbery and kidnapping back in 1989, Fitzpatrick said.

The Diocese of Rockville Centre said in a statement that it is “grateful to law enforcement agencies for helping to bring this tragedy to closure.”

Logsdon dedicated his life to coaching the thousands of ex-cons who cycled through the home and elsewhere, his friends said.

The Anthony House is a transitional residence for homeless men, many of whom are recovering addicts or ex-prisoners. The Society of St. Vincent de Paul, a Catholic volunteer organization, runs the home and temporarily stopped accepting new residents after Logsdon was killed.

“We are doing this with the utmost respect for Deacon Pat and the ministry he devoted his life to. We want to ensure that his mission and good works will continue,” the group said on its website.
