Investigators say Williams is connected to the July 27 shooting that killed one man and wounded 11 others during the annual “Old Timers” community event outside the Brownsville Recreational Center.

Around 2,000 people were in the area for the party, which was coming to a close when the shooting started.

Jason Pagan, 38, was struck by the gunfire and died of his injuries. The eleven other victims wounded by the gunman were all between the ages of 21 and 55.

Earlier this month, police had been looking for two women labeled as persons of interest in the shooting.
