A Madison man who admitted to stabbing the boyfriend of his estranged wife was sentenced to four years in prison Wednesday.

Dale Lisby, 32, was arrested in July 2013 after an incident at Englewood Motel in which he stabbed another man five times. The victim was airlifted to a Louisville hospital where he was treated.

Lisby pleaded guilty in January to battery resulting in serious bodily injury, a Class C felony that carries a sentence of two to eight years in prison.

Appearing in Jefferson County Superior Court, Lisby told the court he knows he stabbed the man but does not fully recall the incident. He classified it as a "blackout" and said he has a history of depression and has had hallucinations before.

He testified that he visited his two children and then-estranged-wife - the couple has since divorced - at the motel the night before the incident. The boyfriend, who Lisby thought was just a friend, also was there.

Lisby returned the next night and said he was angry at his wife after seeing another man in her motel room. The children also were present.

"I was really mad. I wanted her to get rid of him because I didn't like the situation, and she wouldn't," he told the judge.

Lisby said the argument escalated and his wife provided intimate details about her and the boyfriend's relationship to Lisby, who then stabbed the boyfriend several times.

Lisby's attorney Jason Pattison said the argument - which was documented in the initial police report - was a sign of "significant provocation."

"It's not an excuse for his conduct, judge, but it certainly provoked him," Pattison said of the argument.

Superior Court Judge Alison Frazier said the aggravating circumstances in the case - the presence of the children during the attack - and the fact that the victim was not reported to have provoked Lisby - balanced the mitigating factors, which included Lisby's guilty plea and lack of criminal history.

The four-year sentence, which is the advised sentence for a Class C felony, will be served at the Indiana Department of Correction. There will be no chance for probation or community corrections.
