A man hit with an Oklahoma City police Taser earlier this week died Wednesday at OU Medical Center, police reported.
Timothy C. Dennis, 43, died after being on life support for three days.
Police were waiting on the State Medical Examiner's Office to determine cause of death, Capt. Dexter Nelson said.
Police said Dennis tried to flee from police about 7:20 p.m. Sunday in the 1500 block of NE 18 after officers received a call that a man was walking down the street firing a gun.
Officers used a Taser to subdue Dennis. He was shocked once.
Dennis was taken by ambulance to OU Medical Center, police reported.
EMSA personnel resuscitated Dennis while on the way to the hospital and he was put on life support, Nelson said.
Dennis' death is being investigated by the department's homicide and internal affairs units, Nelson said.
According to court records, Dennis had a history of driving under the influence and driving without a driver's license.
He had previously been convicted of a 2008 charge of attempted larceny of a vehicle.
Officials at OU Medical Center said Monday night that Dennis was in good condition, which contradicts information given by police that he was on life support from when he was taken to the hospital until the time he died on Wednesday.
