FORT MYERS, Fla. -- Authorities said a former Tennessee man who struggled with staff at a Florida mental health center died after police shocked him with a Taser stun gun.

Steven Cunningham, 45, collapsed Thursday in the Ruth Cooper Center for Behavioral Health Care parking lot after being hit with the stun gun, authorities said.

Cunningham later died at a Fort Myers hospital.

Center staff called police when Cunningham allegedly became hostile.

An officer responding to the disturbance shot Cunningham with his Taser, a police spokeswoman said.

The stun guns shoot 50,000 volts of electricity into a target.

The officer is on paid administrative leave pending an investigation.

The victim was a former Shelbyville resident.
