Alleged Stockton serial killer had prior convictions in Alameda County
The serial killer allegedly responsible for five deaths in Stockton and one in Oakland had prior convictions in Alameda County, according to law enforcement.
OAKLAND, Calif. - An accused serial killer in Stockton has a criminal history, lost his brother to gun violence in Oakland, and has suffered psychological stress, court records show.
Wesley Brownlee, 43, was arrested Saturday by Stockton police for six deadly shootings, including one in Oakland.
Investigators said Brownlee was found driving around with a gun and mask "on a mission to kill" and "was out hunting" for another victim.
Brownlee was born in San Francisco but grew up in Oakland along Seminary Avenue.
His childhood home was just a few blocks from where Oakland victim Juan Miguel Vazquez Serrano was killed in April 2021.
Court records shed light on Brownlee’s family life and mental state, as first reported by the East Bay Times.
Documents obtained by KTVU show he is one of his mother’s six children with a criminal history that dates back decades.
In May 1994, at age 14, he was accused of sexually assaulting a 14-year-old girl, along with two other boys. Documents say he denied the allegation and instead accused his friends.
Later that year, records show he was arrested and accused of selling cocaine to an undercover officer. He was put on house arrest as a juvenile.

Suspect arrested in Stockton serial killer case: police
Stockton police said an arrest was made in the serial killer case that has haunted multiple California communities. The announcement was made during a news conference Saturday.
In October 1995, his older brother Dale Brownlee, 17, was shot and killed along East 16th Street in Oakland.
Court records say Wesley Brownlee became "very distressed over his death" and his mother said he "seems continuously depressed," suggesting he get therapy.
A probation report states he was found to be "mentally slow" and "learning disabled." Documents say in school he had low grades, poor attendance and didn’t finish high school.
In 1997, at age 18, he was arrested and charged for having a large amount of crack cocaine. Brownlee was sentenced to two years in prison.
After he was out, Brownlee continued to live with his mother in Stockton. His parents had split up years earlier, a probation report says.
But in 2014, he was accused again in Alameda County of selling crack cocaine. The drug crime occurred along East 16th Street right near where his brother was killed.
Records show he pleaded no contest and served some jail time before three years probation.
Fast forward to 2021, and the first homicide linked to Brownlee occurred in Oakland along Harmon Avenue. Serrano, 40, was shot and killed on April 10, 2021.
Police have also connected Brownlee to six other shootings that left five men dead in Stockton. A woman from Stockton was wounded and survived.
