Samuel Weinberg, an 18-year-old from Aptos, California, was killed in a drive-by shooting on April 3, 2015, in Santa Cruz. He was driving a Mercedes SUV at the intersection of North Pacific Avenue and River Street when a silver SUV pulled alongside at a stoplight and an occupant fired a shot that struck Weinberg in the chest. Paramedics were unable to save him and he died at the scene.

Santa Cruz Police investigators say Weinberg, along with Brandon Aaron Thomas, Jonah Kaleikaumaka Namauu, and a fourth person, had been involved in an earlier altercation in a parking lot. On April 4, 2015, Thomas, 22, and Namauu, 23, were arrested and charged with murder, attempted murder, conspiracy to commit a crime, and participation in a street gang; Thomas was booked after attempting to flee by boarding a city bus and had bail set at $1 million. Detectives reported it was unclear which person fired the fatal shot as the probe continued.

If anyone witnessed the shooting, the earlier parking-lot altercation, or has other information that could identify who fired the shot, please come forward.
