On August 20, at 8:02 p.m., Harford County Sheriff deputies were investigating suspicious activity in the area of Route 7 and MD-152 when they attempted to conduct a traffic stop on a red Ford Ranger pick-up truck. The truck operated by an adult male suspect fled from the deputies. The Harford County Sheriff deputies then pursued the truck out of Harford County into Baltimore County west-bound down Route 7 and north-bound on Cowenton Ave., 21128. Baltimore County Police patrol units were notified and responded to the area to assist. The suspect then drove the truck completely around the traffic circle at the intersection of East Joppa Road and Cowenton Avenue, and began to drive south-bound. The truck then drove across the median at the intersection and crashed into a marked Baltimore County Police car that was responding to assist.

The suspect vehicle and the Baltimore County Police car were both disabled at the location. Harford County deputies confronted the suspect who resisted arrest. Deputies were then forced to use their tasers to control and take the suspect into custody. Shortly after being handcuffed, the suspect was initially talking to the law enforcement officers and suddenly began to have a medical emergency. First-Aid was immediately rendered and Baltimore County paramedics responded to the scene. The suspect was transported to an area hospital, where he was pronounced deceased at 9:05 p.m. .

The suspect is not being identified at this time pending notification of the next of kin.
