No charges are expected against the driver of a car involved in a deadly car-motorcycle crash in Pueblo, after police learned the motorcycle rider was traveling at an excessive speed.

Authorities say 56-year-old Mary Lopez was making a left turn in her Hyundai Santa Fe on June 16 when she was struck by a Yamaha motorcycle.

But police Capt. Linda Grisham says traffic division experts have calculated that 21-year-old motorcyclist Brett Bond was traveling between 124 and 145 mph at the time of the crash. Police used video from a nearby security camera to calculate his speed.

Grisham says since speed was the cause of the crash, there was no evidence to charge Lopez.

Bond was wearing a helmet at the time of the accident, but died of his injuries.
