WICHITA (AP) – A Wichita man pleaded guilty to voluntary manslaughter in the stabbing death of a man who was trying to break up a fight.

22-year-old Christopher Cervantes was scheduled to go on trial this week for second-degree murder. Instead, he pleaded guilty Wednesday to voluntary manslaughter in death of 30-year-old Bradley J. Wellbrock.

Wellbrock was killed in January 2012 after intervening in a dispute between a man and a woman.

Cervantes’ attorney said the stabbing occurred during a brawl involving two groups of people.

Cervantes will be sentenced April 24.
