TAYLORSVILLE — A 51-year-old bicyclist riding without a helmet or reflective gear was hit and killed by a car early Sunday.

Brad Hendricks, of Millcreek, was riding west near 1600 W. Taylorsville Expressway (4500 South) about 2:25 a.m. when he was struck from behind by a 29-year-old man driving with his wife and 7-month-old son, said Unified Police Lt. Justin Hoyal. The driver apparently did not see the cyclist until it was too late.

"Obviously, it's very traumatic for anybody to be involved in something like that," Hoyal said.

The cyclist, who was in a travel lane, died at the scene.

The speed limit in the area is 50 mph. Hoyal said investigators were still looking Monday into what Hendricks was doing at that early hour, why he was riding a bicycle and where he was headed.

No citations were issued as of Monday. Alcohol and drugs do not appear to have been a factor in the crash, though the incident remains under investigation, Hoyal said. A crash analysis reconstruction team responded to the scene and will turn a report of its findings over to the Salt Lake County District Attorney's Office to screen for any potential charges.
