STOCKTON, Calif. — A man suspected of committing serial murders in Northern California was charged with four additional murders this week, bringing the total to seven deaths since April 2021, authorities said.

Shootings terrorized the Central Valley city of Stockton earlier this year as police searched for a man dressed in black who appeared to be “on a mission” as he searched for victims for ambush-style shootings. He, too, was linked to the violence in Alameda County.

Three of the four murders listed in court documents Tuesday have already been disclosed by authorities, who previously said they had linked suspect Wesley Brownlee to the killings of six men and the wounding of a woman, but no charges had been filed.

The fourth case on Tuesday, an April 2021 murder bringing the total to seven murders, was previously unreported.

Brownlee was arrested in October when he «was looking» for another possible victim in Stockton, police said at the time. He is scheduled to appear in court on January 3. His public defender, Allison Nobert, did not immediately respond to a request for comment.
