The son of a high-ranking Baltimore police commander was arrested on Tuesday after officials say he stabbed his roommate multiple times, killing him, WJZ-TV reports.

28-year-old Melvin Russell—son of Lt. Col. Melvin Russell—was charged with first- and second-degree murder, assault and weapons violations after allegedly stabbing the victim in a fight in Southwest Baltimore on Monday. From The Baltimore Sun:

Police said he and his 49-year-old roommate got into a fight in the 4900 block of Challedon Road and both sustained stab wounds. Both were taken to hospitals, where the roommate was pronounced dead, police said. The victim was not identified. Russell was treated for his injuries and released.

As head of the department’s Community Collaboration Unit, the elder Russell has played an important part in trying to build ties between Baltimore’s citizens and the officers that police them.

“I always ask first do you want to see peace, hope and love restored to the community. If we can use that as our foundation, we can accomplish a lot,” Lt. Col. Russell told the Baltimore Afro-American in May. “It’s difficult to sell drugs when 20 or 30 people from the church turn out en masse in an open-air drug market to send a signal that they don’t want this in their community.”
