A 34-year-old Cumming man was shot and killed by a Cobb County police officer and the department is now conducting an internal investigation.

According to a statement, Matthew R. Murdock died early Friday, about 2 ½ hours after he was shot Thursday night at Puckett Drive and Mableton Parkway.

The police statement said an officer stopped Murdock as he was driving out of a Mableton parking lot in a green 2003 Volkswagen Passat. The police said Murdock was stopped because he was a “suspicious person.”

Moments later, a Cobb County deputy pulled up.

While the officer was checking Murdock’s information, the deputy got into a scuffle. A second Cobb police officer pulled up at that time.

“As the male continued to disobey the lawful commands of the officers, and when it appeared that he was reaching for a weapon, the second Cobb County police officer shot the male stopping his actions against them,” the police statement said.

The names of the officers were not released. They are on paid leave until the internal investigation is completed.
