Authorities have issued an arrest warrant for 29-year-old Tremaine Wilbourn, the man believed to have shot and killed a Memphis police officer this weekend, the Associated Press reports.



“You can be assured that we will continue to pursue this suspect and we will exhaust all means until he is in custody,” said Memphis Police Director Toney Armstrong on Sunday.

Wilbourn is suspected of fatally shooting Officer Sean Bolton, 33, during the investigation of a parked car last night. From CBS News:

According to police, Bolton saw a vehicle that was illegally parked when he pulled in front of it and illuminated it with his spotlight. When he approached the vehicle, he was confronted by the passenger and a brief struggle ensued between the two of them. The passenger drew a weapon and shot Bolton, multiple times, police said. Police said a civilian had used Bolton’s radio to notify police about the shooting.

According to the news network, the driver of the vehicle later turned himself into police and has since been released without charges.

U.S. Marshals have offered a $10,000 reward for information leading to the arrest of Wilbourn. He is considered armed and dangerous.
