Police are searching for a 22-year-old man suspected of stabbing his father and grandfather to death at a Decatur home.

Decatur Assistant Police Chief Keith Lee says Miller Jordan III is wanted for two counts of murder in the deaths of Miller Jordan Sr. and Miller Jordan Jr.

Police have not revealed how the killings took place.

Clarke County school officials say Miller Jordan Jr. was assistant principal at Clarke Central High School, the Athens Banner-Herald reported.

The school official lived in Decatur with his three children and wife, Gale Jordan, an assistant principal at Kennedy Elementary School in Barrow County. School officials say they were notified of the killing Sunday evening but had few details other than that.

"It's just been a tremendous shock," Clarke Central Principal Maxine Easom told the Banner-Herald. "It's really unbelievable."

Police say the suspect is believed to be traveling in a green 2001 Nissan Altima, and is known to frequent various hotels on Lawrenceville Highway near I-285. They advise anyone having contact with him to use extreme caution.
