Wesley Brownlee, 43, was charged with three counts of murder on Tuesday. He is suspected of killing a total of six people over the course of 18 months in Stockton, California.
Natasha LaTour, 46, was shot multiple times by Wesley Brownlee at a train station at 3.20am on April 16 last year. Brownlee, 43, has now been arrested on suspicion of at least six murders in California.
California Police have released surveillance footage of a person of interest in connection with a string of six murders and said the crimes could be the work of a serial killer on a mission.
