The case was originally reported as an incident of road rage, but detectives now say Jalexus Washington and his mom were seen at 9:38 a.m. at a donut shop at the corner of Walnut Street and Abrams Road. Twenty minutes later, the woman arrived at the emergency room of Medical City Hospital seeking treatment for her son.

He died of his injuries.

Fox 4 News reports that the mom claimed she was the victim of road rage near Forest Meadows Park at Whitehurst and Arbor Park, and neighbors there observed Dallas police officers retrieving a gun from the woods. Police have not confirmed if a gun was found or tied to the case.

Dallas police are asking for assistance from anyone who can shed light on what happened between the donut shop and the hospital arrival. The woman was driving a 2011 dark blue Suburu Legacy with paper tags.
