A Clayton County police dog died after battling a brain tumor, Sheriff Victor Hill said Friday.

Adam, a 9-year-old German Shepherd, conducted security sweeps at the Clayton County courthouse, schools and events throughout the county, the sheriff said. Along with his handler, Lt. Michael Hensley, Adam also searched for missing children and suspects, according to the Clayton County Sheriff's Office.

"Adam showed courage and continued to press the fight till the day he was laid to rest," Hill said in an emailed statement.
