The Sacramento County Sheriff’s Office released a sketch Tuesday, hoping someone has seen the suspect wanted for this brutal attack.

“It was shocking. I would never think such a thing,” said Angelo DeStephano, who lives near the scene.

The woman in her mid-20’s was walking across a pedestrian bridge over Highway 50 toward Salmon Falls Park. That’s when investigators say a man came up and physically and sexually assaulted her, causing serious injuries. Fortunately, a Good Samaritan scared the man off and was able to describe the attacker to authorities: A tall thin black man between 20-30 with a short afro and two gaps in his top teeth. Detectives say he appeared “transient looking.”

“We get all kinds of people through here because we are close to trade-in places where they can trade in cans,” said DeStephano.

“They used to come every day and shoo them out but it’s been a lot better,” said another woman who didn’t want to be identified who also lives near the bridge.
