RHINEBECK, N.Y. (AP) -- Police say they're investigating the death of a 44-year-old New York man who died after a sheriff's deputy used a stun gun to subdue him.

Police responded to a domestic dispute and possible drug overdose early Wednesday morning in Rhinebeck, 50 miles south of Albany.

Authorities say they found James Healy Jr. behaving irrationally inside his girlfriend's house. Police say Healy became combative and resisted being removed from the home.

Officials say a deputy used a stun gun on Healy during the struggle. Police say he continued to struggle before officers were able to subdue him.

State police troopers say Healy then had trouble breathing and was taken to a hospital, where he was pronounced dead. The cause of death was pending an autopsy.
