WICHITA, Kan. (AP) — A man who shot and killed one person and injured four others at an after-hours warehouse party in Wichita was sentenced to life plus 21½ years in prison.

Marquel Dean was sentenced Thursday in Sedgwick County for first-degree premeditated murder and five other counts for the shooting that killed James Gray in July 2013. Police say the shooting occurred after a long-running gang feud.

The Wichita Eagle reports Dean cannot begin serving the 21½ year sentence until he is paroled on the life sentence. He’ll serve at least 46½ years in prison.

A co-defendant in the case, Shane Landrum, is awaiting trial for first-degree premeditated murder and eight other crimes. He is being held in Sedgwick County Jail in lieu of $500,000 bond.
