Police say they've arrested the 28-year-old driver of a van in the death of his friend, a passenger who was shot by another person in Northern California.

The Redding Record-Searchlight reports that William Roy Thietje was taken into custody Sunday for investigation of involuntary manslaughter and felony assault.

Shasta County sheriff's officials say the incident began when Thietje rammed his van into another parked car in a fit of rage while looking for an ex-girlfriend at Shasta Lake.

Officials say a neighbor then shot at the van to stop it from running over a pedestrian. The bullet struck and killed Thietje's friend.

Sheriff's officials say they believe Thietje's actions caused the death, and the homeowner saved the pedestrian's life.

Sheriff's officials told The Associated Press that Thietje is being held at the Shasta County Jail but doesn't have an attorney. His arraignment is scheduled for Wednesday.
