EASTON, Pa. (AP) - A man has been found dead after a five-hour standoff with police in eastern Pennsylvania.

Authorities say the man was found in his home Monday night. Police surrounded the Easton home just after 5 p.m. after they received reports of a domestic disturbance involving a man with a rifle.

Police negotiators pleaded with the man to come out of the house and used a flash-bang device before sending a robot in just before 10 p.m. Officers went in after the robot and found the man.

Police say the man had been dead for hours before they entered the home.

The Northampton County coroner is working to identify the man and determine his cause of death.
