Police on Monday were investigating another Highway 4 shooting, the latest in a rash of gunfire incidents on or near the highway in Contra Costa County in recent weeks.

All lanes of westbound Highway 4 from Loveridge Road to Railroad Avenue were closed Monday afternoon during the investigation, according to the California Highway Patrol. The highway reopened around 6:30 p.m.

Just before 3 p.m., Antioch police heard reports of shots fired by two people in a black Jaguar on the 1100 block of Sycamore Drive near a Highway 4 onramp. No one was injured but cars parked nearby were hit by gunfire.

The Jaguar and a second car then drove onto westbound Highway 4. In a statement, police said there were reports of shots being fired between the two cars on the freeway, but they could not confirm those reports.

Both cars were stopped several miles away — one at a gas station on Bailey Road in Bay Point and the second on Highway 4 — by Antioch police and the California Highway Patrol. Four people were taken into custody, according to Antioch police.

It’s not clear whether the most recent shooting is related to earlier incidents.

In April, a drive-by shooting appeared to be a targeted attack on the victim, who was driving west on Highway 4 near Loveridge Road in Pittsburg. He was shot multiple times and died of his injuries.

Last Wednesday, a woman was killed and a man was injured in a shooting in the same general location, near Loveridge Road. Their car was hit multiple times before the driver lost control and the vehicle crashed and rolled down an embankment. Authorities said that attack, too, appeared to have been targeted.

There has been a rash of similar shootings on nearby highways, too, though authorities don’t believe they are connected.
