Elizabeth Begaren, a Department of Corrections officer, was fatally shot after armed assailants stopped her and her family in their car on a 91 Freeway off-ramp in Anaheim in 1998.
Nuzzi Begaren, Elizabeth's husband at the time, was arrested Monday with two other suspects. Police were still seeking a fourth suspect.
Three days after the murder, Nuzzi Begaren described to the L.A. Times how the Jan. 17, 1998 incident allegedly occurred. He said he and Elizabeth and her 10-year-old stepdaughter were stopped in their car by a car full of assailants at the off-ramp.
He said Elizabeth decided to run, saying they would die if they stayed in the car. When one of the assailants caught up to her, she identified herself as a law-enforcement officer and showed her badge, according to Nuzzi, and she was subsequently shot.
Nuzzi claimed the men were after cash. He offered police a suspect vehicle description and a license plate number.
The couple had been married for six months.
