SAN JOSE — Former San Francisco 49er Dana Stubblefield was charged Monday with the rape of a “developmentally delayed” woman, according to the Santa Clara County District Attorney’s Office.

Prosecutors said the woman was assaulted on April 9, 2015, when she went to his Morgan Hill home to interview for a baby sitter’s job. The 5-foot-tall, 105-pound woman immediately reported the alleged crime to the Morgan Hill Police Department.

Stubblefield, 45, who stands 6-foot, 3 inches tall and weighs 310 pounds, is charged with five felony counts related to assault and faces a “substantial prison sentence” if convicted, according to prosecutors.

“This was a crime of violence against a vulnerable victim,” said Deputy District Attorney Tim McInerny in a statement. “She was looking for a job and she was unconscionably assaulted.”

Bail for Stubblefield is set at $250,000. His arraignment is scheduled to take place Wednesday at 1:30 p.m.

Stubblefield contacted the woman through Sittercity.com to see if she was interested in a job as a nanny, according to a Morgan Hill police report. They set up an interview for the next day at Stubblefield’s home.

The interview lasted about 20 minutes. The woman left. Minutes later she received a text message from Stubblefield saying he wanted to pay her for her time that day. She went back to the house where Stubblefield picked her up, carried her to a room and raped her, and forced her to “orally copulate him,” the report says.

Stubblefield gave her $80 and let her go. The woman drove straight to the Morgan Hill Police Department, where she reported being assaulted by a man named “Dana.”

DNA evidence matched that of Stubblefield, the report said.

Stubblefield’s lawyer, Kenneth Rosenfeld, did not respond to a request for comment.
