OAKLAND — The man shot and killed in West Oakland on Friday was a father of three and a father figure to the Oakland youth he coached on the football field and the students he helped as a school counselor.

DeAndre Green, 34, was known to purchase everything from mattresses to football cleats for his students, his family said Sunday. Green was an assistant football coach at Oakland Technical High School, worked as a counselor at Castlemont High High School in East Oakland and previously coached at Contra Costa College in San Pablo, where he was a star wide receiver.

“In everything, he came last,” his nephew, Pastor Phil Miller said. “He never put himself first.”

Green was wounded in a shooting reported at 3:05 p.m. Friday in the 1700 block of 14th Street, near Pullman Way. He was later pronounced dead at the West Oakland building where he lived.

Police have not released a motive yet for the shooting, and no arrests have been made.

Born and raised in Oakland, Green attended De Anza High School in Richmond after his family moved to West Contra Costa. As a child, he “played church,” pretending to be the congregation’s pastor and making Miller his deacon. At the time of his death, he was a deacon at Miller’s church, Humanity Baptist Church in North Oakland.

After graduating from De Anza, Green earned a scholarship to Alabama A&M University but returned to play at Contra Costa College. He transferred to Montana State University, where he graduated with a degree in sociology.

Beyond coaching youth in Richmond and Oakland, most recently at Oakland Tech, Green worked with at-risk students as a Castlemont school counselor, his mother said.

“He had a big heart,” his mother, Melba Green, said. “He worked with homeless kids and would buy them mattresses, cleats” whatever they needed.

His family said he recently agreed to a job working with San Jose’s homeless residents.

“I want people to know you can be young and fly but live your life with a purpose,” Miller said. “He was such an inspiration.”

Green is survived by his wife, Snowtavia, and their three children ages 12, eight and six; his parents, Donnie and Melba Green, who have been married 45 years; two brothers and two sisters.
