Christopher Seda, 24, was killed in a shootout in the parking lot of the Boardwalk Bowl Entertainment Center in Orlando on the evening of April 12, 2015. The exchange of gunfire followed an argument among a group gathered there; two other people were seriously injured and did not cooperate with investigators during the initial inquiry.

Investigators determined the confrontation was tied to a drug deal that went wrong. Courtley Tillman, 22, and Warrick Ross, 23, were identified as the primary suspects. According to the Orange County Sheriff’s Office, Tillman tried to rob Seda and another man during the transaction, triggering the shootout. Both Tillman and Ross were arrested and charged with first-degree murder and attempted murder.

Tillman’s background included prior arrests and a December 2014 incident in which he shot and killed a man during a physical confrontation; that earlier shooting was ruled justified and he was not charged at the time. Many details about the incident and the motives remain tied to the larger drug-related dispute.

Anyone with information about Seda, the Boardwalk Bowl parking lot that night, or the events leading up to the shooting is asked to come forward.
