AURORA (CBS) — Investigators in Aurora are awaiting autopsy results on a suspect who died after being tasered by police last night.

Witnesses said around 10 p.m., officers responded to the 700 block of Fourth Avenue after 911 callers reported a man acting wildly and jumping on parked vehicles.

An officer observed Jersey K. Green, also of the 700 block of Fourth Avenue, on top of a parked SUV. When Green saw the officer, he jumped off the vehicle and began running.

Green then run toward another officer’s fully-marked squad and jumped on the hood. As the officer was exiting the squad, Green apparently moved toward him, according to a news release from the Aurora Police department.

Green’s actions led the first officer to use his Taser to strike Green in the upper thigh and side. The two officers then struggled with Green who was eventually taken into custody.

An ambulance was immediately called to check over Green since a Taser was deployed on him. Aurora Fire Department Paramedics arrived at 10:04 p.m. and began treating Green, placing him inside the ambulance for evaluation.

While inside the ambulance, Green became combative with paramedics and had to be restrained with the assistance of the police. He also spit out a bag that contained a substance that appeared consistent with crack cocaine.

At approximately 10:24 p.m., while still in the ambulance, Green lost consciousness and stopped breathing. Paramedics began CPR and transported him to Rush Copley Medical Center where he was pronounced dead.

An autopsy on Green is tentatively scheduled for later today.
