A woman suspected of being armed with a gun died after she ran to the 57 Freeway and was struck by an SUV in San Dimas on Monday night.

She had entered the freeway from Arrow Highway and was trying to cross freeway lanes, according to a California Highway Patrol statement. The medical examiner’s office has not yet publicly identified the woman.

Deputies were looking for the woman when the CHP notified them about someone who had been hit on the freeway, according to sheriff’s Sgt. Rick Duarte. Deputies weren’t chasing her, he added.

The sheriff’s San Dimas station received a call at 9:11 p.m. about a woman at Bonita and Eucla avenues yelling at herself and possibly pointing a gun, Duarte said. There was an earlier, similar call at Pioneer Park, he said.The woman, described as blonde, between 30 to 40 years old and wearing a gray hooded sweatshirt, was last seen heading towards a Best Western, he said.

At 9:29 p.m., a caller reported to the CHP that a vehicle struck a pedestrian running on the southbound 57 Freeway, south of Arrow Highway, CHP Sgt. Alfonso Campos said. The vehicle was a gray Honda CRV.

Officers found the woman lying near the freeway shoulder, he said. The driver got off the freeway at Covina Boulevard and waited for the CHP. The driver wasn’t arrested, Campos said.

The CHP release did not mention a gun.
