Shortly after 1:30 am Sunday morning- KC-MO police observed a vehicle driving erratically on the city's east side so ground officers summonded Helicopter 690 to track it.
KC-MO PD-690 followed from well above that erratic vehicle- now going northbound on Cleaver II Boulevard- speed reported by the chopper's observer to be "90 to 100 MPH."
At 1:41 am- the police helicopter's crew witnessed the vehicle crash into another containing 3 people and "demolish" a light pole at 39th Street.
One person- believed to be a female- was thrown from the struck vehicle and died at the scene.
Another male passenger in the struck vehicle was critically injured- a 3rd male had fairly minor injuries.
The driver and a passenger in the speeding vehicle ran after the crash.
Helicopter 690 kept track of the driver from the air. Both suspects were apprehended after about 20 minutes and one of the men was bitten by a police dog.
Police in their cars had stayed well behind the erratic vehicle before the crash and were not chasing it.
