A Haltom City woman died from injuries she suffered after falling off a motorcycle and getting hit by another vehicle on Airport Freeway in North Richland Hills, police said Monday.

Kelly Erwin, 39, fell off the motorcycle, which was being driven by her husband, Jeffrey Erwin, 56, about 4:30 p.m. Sunday after it hit a vehicle, authorities said. Then another vehicle hit her.

Before paramedics and police arrived, Jeffrey Erwin rode away. He was arrested at the hospital where his wife was taken and faces a charge of failing to stop and render aid, a third-degree felony, North Richland Hills police said Monday.

"He had gone to the hospital to check on her condition," North Richland Hills investigator Keith Bauman said Monday.

Jeffrey Erwin was in the North Richland Hills Jail with bail set at $7,500.

The crash occurred in the 8600 block of Airport Freeway. The driver who struck the woman was cooperating and no charges are expected to be filed against that motorist.
