Doug Martin, a Stockton high school football standout who went on to a stellar NFL career, died in police custody in Oakland amid an ongoing struggle with mental illness. He was 36.

As a NFL standout running back, Martin had played for the Oakland Raiders and spent six seasons with the Tampa Bay Buccaneers, including appearances in the NFL’s Pro Bowl. He has been honored as one of the top 50 Buccaneers of all time.

His gridiron prowess first became apparent at St. Mary’s High School in Stockton, where he was a member of the Class of 2007. He went on Boise State University before turning pro.

“Our deepest sympathies go out to his family, and certainly his teammates and his friends and his coaches,” St. Mary’s football coach Tony Franks said. “There was a lot of people in his world that he touched, certainly when he was in our community and the other places he’s been in his life. This is a tough one for a lot of people.”

At the time of his death, Martin had retired from football. He was listed by police as still a Stockton resident, had been arrested after he broke into a home in Oakland at 4:15 a.m. Saturday. A brief struggle occurred as officers attempt to take into custody and he became unresponsive, Oakland Police said.

Paramedics tried to revive him and he was taken to a local hospital where he died.

Martin’s former manager and now CEO of Athletes First, Brian Murphy, issued a statement on behalf of the family. He said Martin had been “deeply committed to serving the communities of Boise, Oakland and Stockton “where his generosity and spirit were well known.”

But Murphy noted that Martin’s mental-health issue, “the one opponent from which Doug could not run.”

He also said Martin’s parents were seeking medical help for him and had been in contact with local authorities.

“Feeling overhwhelmed and disoriented, Doug fled his home during the night and entered a neighbor’s residence two doors down where he was taken into custody by police. An investigation in what transpired as he was detained was underway,” the statement said.

Martin’s mother, Leslie Baranco Martin, is a former city councilmember and was the first Black woman appointed vice mayor of Stockton during the term of Mayor Ed Chavez (2005-2009).

In a statement, the Buccaneers said the team was “deeply saddened” by Martin’s passing. From the time he was record-setting rookie in 2012, “he made a lasting impact on our franchise.”

The Raiders also released a statement, saying in part “The Raiders Family was saddened to learn of the recent passing of Doug Martin. (A resident of) Stockton, Martin joined the Silver and Black in 2018 after six seasons in Tampa Bay, and he led the Raiders with 723 rushing yards that season. The condolences of the entire Raider Nation are with Doug’s family at this time.”

Martin remained loyal to St. Mary’s. In a video message to the Class of 2020 that’s still on social media, Martin wished graduates the best and ended his quick message with an enthusiastic “Ram pride, baby!”
