About 2 a.m. Monday morning, officers responded to reports of a crash near McKinley Avenue and Fresno Street. One vacated car was found in the middle of McKinley, while another was spotted in the canal.

Officers initially recovered the Martha Hernandez’s body, and they later found her son in the canal about two miles away.

Fresno police chief Mindy Casto said Hernandez was exiting Highway 41 at McKinley Avenue when a Honda Pilot allegedly ran a red light, crashing into her vehicle.

The force of the crash launched Hernandez’s car into the canal, Casto said.
