Two rival gangs were involved in the shooting that killed Mario D. Brown, 22, early Saturday morning and injured another

Two rival gangs were involved in the shooting that killed Mario D. Brown, 22, early Saturday morning and injured another, Lt. Ken Landwehr said.

It would be the first gang-related homicide of 2011, Landwehr said, because this is the first time this year where all those involved in the incident were gang members.

Police are still looking for the suspect.

Shortly before 2:30 a.m. Saturday, more than 100 people gathered for an after-hours party in a parking lot at 3105 E. 13th St., between 13th and Lorraine.

A white-over-black SUV pulled up, words were exchanged between Brown and someone in the vehicle. Multiple shots were fired, striking Brown in the chest, and injuring a 25-year-old man in the leg and arm.

Brown later died at the hospital. The 25-year-old has been treated and released, Landwehr said.

According to witnesses, Landwehr said Brown and the man who did the shooting had argued earlier in the evening at a Wichita club.

"We believe (Brown) was targeted," Landwehr said.

More than 20 witnesses were interviewed by the police, but so far the shooter's identity isn't known.

"I'm sure there were several people present who know the individual's name," Landwehr said, "but it hasn't been revealed to us yet."
