AUBURN — A man accused of attempted murder stemming from an alleged assault on a female roommate is expected to plead guilty later this week in connection with the incident.

Mark McLaughlin, 51, of Lewiston was scheduled to be tried later this month on charges of attempted murder, elevated aggravated assault and aggravated assault.

As of Tuesday, the prosecutor and McLaughlin’s lawyer had not reached a plea agreement.

McLaughlin is being held without bail at Androscoggin County Jail. He was found competent to stand trial following a mental examination.

A woman who shared a Blake Street apartment with him was stabbed in the chest and back, then made her way to a nearby hospital in September.

Cathy Mason, 57, told police she was in bed when McLaughlin came into her room and told her: “This is your night to die.” He stabbed her several times before she was able to flee her bed, she said. She told police she struggled with McLaughlin and fled the apartment.

In the hallway, McLaughlin pulled her hair to keep her from escaping, she said. She said she thought McLaughlin stabbed her in the back as she was heading for the building’s exit.

She wrestled the knife away from McLaughlin as he repeated his threat. When McLaughlin lunged at her, she slashed the knife at him. She left the building as McLaughlin followed, she said. She threw the knife in some tall weeds so that McLaughlin couldn’t use it again to hurt her, she told police. She continued to the hospital where she saw a woman standing outside. Mason told the woman she’d been stabbed. Hospital security escorted Mason to the emergency room.

She told police McLaughlin had been drinking before the stabbing.

McLaughlin told police she was the one who stabbed him first. He said he forced the knife from her, and then stabbed her.

Police said they went to the apartment and found McLaughlin wearing only dark-colored boxer shorts and holding a knife. His face and hands were covered with blood, police said.

McLaughlin suffered a laceration to the lower abdomen, a puncture wound to the upper chest, a laceration to the upper left eye and multiple abrasions. Paramedics took him to Central Maine Medical Center.
