COBB COUNTY, GA — A welfare check involving Cobb County police led to a deadly shooting at a home on Vandiver Drive near Sandy Plains Road.

When officers arrived at the home, officials say a man later identified as 29-year-old William Peake refused to answer the door. The welfare check was requested by a concerned family member.

A few hours later, officers heard a shot from inside the home. That’s when SWAT and negotiators were called to the scene. Authorities used a drone to look inside and saw a man armed with a handgun, along with another person inside the home.

Police say the man later fired toward officers, who returned fire and injured him. Negotiations continued until authorities say the man shot and killed himself.

Police officials say 71-year-old Lorrie Peake was killed by her son William Peake.

No officers were injured in the incident.

The Georgia Bureau of Investigation has been called in to investigate the officer-involved shooting.

The investigation remains ongoing.
