Updated 3/16/18 at 5:45 p.m. ET: The deceased individual has been identified as Mark Clinton Harrell, Jr. (DOB 8/9/91), of Church Hill, TN.

At the request of 1st District Attorney General Tony Clark, TBI Special Agents are investigating the circumstances that led to an officer-involved shooting Friday afternoon in Jonesborough.

Preliminary information indicates that just before 1:00 p.m., the Jonesborough Police Department received a complaint concerning possible drug activity at a hotel located along East Jackson Boulevard/ Highway 11E. Upon arrival, officers encountered a male subject in the parking lot. The man displayed a large knife and threatened to harm himself before leading officers on a foot pursuit. The foot pursuit crossed over E. Jackson Boulevard and ended in the 400 block. Officers continued to give the individual orders to drop the weapon, but he refused to comply.  At some point during the second confrontation, the subject reportedly moved toward one of the officers with the knife. The situation further escalated and resulted in the officer firing his service weapon, striking the subject. He was transported to a local hospital where he was pronounced dead. No officers were injured during the incident.

TBI Special Agents will gather any and all relevant interviews and evidence as part of this ongoing investigation. Throughout the process, Agents will submit investigative findings to the District Attorney General for his review and consideration.

Additionally, the TBI does not identify officers involved in these types of incidents and instead refers questions of that nature to their respective department.

Updates on this investigation will be posted online at TBINewsroom.com as they are available.
