A woman was shot to death and a man injured in Brighton Sunday night.

The Jefferson County Coroner's Office identified the fatality victim as Misty Sheffield Martinez. She was 41, and lived in Lincoln. Authorities were notified of the shooting after both victims showed up at UAB West about 9 p.m.

Martinez, wounded in the chest and left arm, was pronounced dead at the hospital at 10:16 p.m. The man who drove her to the hospital was treated for a gunshot wound to the chest. His name has not been released.

Details are sketchy, but authorities said the initial information is that Martinez was riding in a vehicle with her friend when an acquaintance of the friend flagged them down and asked for a ride. He then directed them to an alley, where he said he was going to get out.

Instead, he pulled a gun and demanded the vehicle. It's unclear what happened next, but he fired shots and the driver pulled off and headed toward the hospital.

Efforts to reach Brighton police officials weren't immediately available. This story will be updated as more information is released.

The death is Brighton's second homicide this year, and marks the 59th in all of Jefferson County for 2017.
