All five people were from Tracy, authorities say.

California Highway Patrol had said that the group was in a 1997 Toyota heading northbound on I-5 when, for an unknown reason, the car went off the freeway and struck a tree near Roth Road.

Three of the passengers were pronounced dead at the scene, officers say. The other two people later died at the hospital.

Investigators said three people who were in the back seat of the car were not wearing a seatbelt.

It’s believed that drugs and/or alcohol were involved in this crash, CHP said.

Family and friends have since left stuffed animals and other items at the scene of the crash to pay tribute to the lives lost.
