COLLEGEDALE – On Wednesday afternoon, Collegedale Police responded to a domestic assault complaint at a residence in the 5800 block of Karen Street, located within Grindstone Estates. The suspect, identified as 60-year-old Mark Joseph Contorelli, barricaded himself inside the home after authorities arrived.

Armed and refusing to surrender, Contorelli barricaded himself inside the home, prompting an escelated response from Collegedale police. With support from the Hamilton County Sheriff’s Office SWAT Team, authorities successfully brought the standoff to a peaceful conclusion. Contorelli eventually surrendered without incident and was taken into custody.

“Thanks to the outstanding work of the negotiators and the coordinated efforts of all the responding officers, this situation was resolved peacefully,” said Chief Jack Sapp. “We are grateful for the assistance provided by the Hamilton County Sheriff’s Office.”

He has been charged with Domestic Assault and is scheduled to appear in court on January 15, 2025.
