California Highway Patrol officials are investigating links between South Bay freeway shootings after a third car was shot at in just 24 hours, authorities said Wednesday.

Around 10 p.m. Tuesday, a man was driving southbound on Highway 17 near the Highway 85 junction in Los Gatos when he heard a thud on the back of his car, CHP spokesman Ross Lee said.

“When he got home, he looked in that area and saw what appeared to him to be a bullet hole,” Lee said.

CHP officers responded to the man’s residence and confirmed the bullet hole. Authorities do not have any information on a suspect vehicle.

The shooting happened less than two hours after a mother and daughter were traveling southbound on Interstate 680 near King Road in San Jose when a bullet went through the car’s window, officials said.

The bullet did not strike the woman or her daughter, but shards of broken glass cut the 12-year-old girl, Lee said.

Around 10:22 p.m. Monday, a 30-year-old man was shot and killed while driving northbound on I-680 just north of Landess Avenue in Milpitas, authorities said.

Officers responded to the scene and found Mathew Rios, of Milpitas, unresponsive in the driver’s seat of a gray Toyota Camry. He was declared dead at the scene.

All three incidents are still being investigated. Anyone with information can call CHP’s tip line at 707-917-4491.
