(WSB Radio)  A six year old child is dead and his grandfather is in custody, charged in the killing.

Police were called to the home  on Troy Street in Commerce at about 1 o'clock Sunday afternoon.  An officer went to the front door, sparking an exchange of gunfire.

"When he (the officer) tried to make contact at the front door, he reported the suspect inside fired a round at the officers," says Commerce Police Chief John Gaissert.  "They then made a tactical retreat."

Officers returned fire and were able to make their way into the house.  It was there that they discovered the dead boy.

"Michael Levine, age 6, was deceased on the scene of an apparent gunshot," says Chief  Gaissert. 

Police also found Clark's 58 year old wife Linda in the home.  She had been shot and wounded by her husband.

"Mr. Clark is the suspect in the shooting of both his wife and the child," says Gaissert.

According to police the Clarks had custody of Michael and a 5 year old boy.  The other child was able to escape the house unharmed. 

The chief says Clark was wounded in the exchange of gunfire. 

Gaissert says police bullets only hit Mr. Clark and not the boy nor Mrs. Clark.

"The GBI has confirmed to me that police gunfire did not strike anyone but the suspect," he says.

Both Clarks are expected to survive.  Police say they do not know what provoked the shootings.
