(WSB Radio) -- A nationwide manhunt for former UGA Marketing Professor George Zinkhan is over.

Cadaver dogs found Zinkhan's body Saturday in thick woods 1000 yards behind an Athens-area elementary school.

Investigators say Zinkhan apparently dug his own grave, covered his body with debris and fired a single gunshot to his head.

His body has been taken to the State Crime Lab for positive identification using dental records and an autopsy.

The manhunt for Zinkhan began April 25 following the shooting deaths of his wife, Marie Bruce, Tom Tanner and Ben Teague at the Athens Community Theater.  The three were all members of the Town and Gown Players. 

Authorities recovered Zinkhan's vehicle, a red Jeep Liberty on April 30 in woods near where his body was found - all about three miles from his Bogart home.  More than 200 law enforcement agents spent last Friday searching the area where the Jeep was found for Zinkhan.

His body turned up outside the original search area.  Investigators brought out the Cadaver dogs Friday but did not discover Zinkhan's body until a return search Saturday.
