An Albion man was sentenced Monday in Orleans County Court to 20 years in state prison for the 2005 stabbing death of his wife.
Matthew E. Farrow, 46, earlier pleaded guilty to first-degree manslaughter. He originally had been charged with second-degree murder in the death of his wife, Anne-Marie, 43.
"I know what I've done is the most horrendous occurrence that has happened to us," said Farrow, who expressed remorse in court.
Farrow stabbed his wife in the chest with a 22-inch knife, court officials said.
At his arrest, he said he believed his wife was having an affair. She had told him she was kicking him out of their Route 31 home the night he killed her.
Investigators said the victim's screams awakened the couple's 10-year-old daughter, who called Orleans County 911.
District Attorney Joseph V. Cardone said he agreed to the plea deal for several reasons, including a possible defense involving extreme emotional disturbance. Cardone also said he wanted to save the daughter from testifying against her father.
Orleans County Judge James Punch said he did not accept that Farrow was disturbed at the time of the incident, saying: "I think you had full faculties about you when you did this."
Court officials said police and paramedics rushed to the one-story home, where they said they found Anne-Marie Farrow still alive at about 3:30 a.m. She died about 45 minutes later in Medina Memorial Hospital.
