A woman's body has been found in a car stopped along the side of the 10 Freeway in El Monte Tuesday morning, prompting an hourslong closure of eastbound lanes that severely snarled traffic for about nine hours.
Investigators were called to the scene after a tow truck driver spotted the car, a white 2011 Chevy Malibu, crashed into a wall along the freeway's right shoulder near Peck Road and decided to render aid, CHP Officer Chris Baldonado said.
The truck driver called 911 after discovering the woman inside was unresponsive.
The victim, a Hispanic woman in her 30s, had a gunshot wound in the right side of her head, Baldonado said.
A SigAlert was first issued near Peck Road due to "police activity" at about 4:30 a.m. and expanded to all lanes of eastbound traffic just before 5 a.m., according to the California Highway Patrol’s traffic incident website. It wasn't until just after 1:30 p.m. that all lanes reopened.
A tarp could be seen over the driver's side window and windshield of the car as detectives combed the freeway for clues Tuesday morning.
Detectives are investigating the incident as a homicide.
So far, investigators have been unable to determine where the shooting occurred and are considering whether a passenger could have pulled the trigger then run off, according to Baldonado.
