ALAMEDA -- A transient has been linked to the mugging of a 78-year-old woman in August after his female accomplice pleaded guilty in the case, police said Wednesday.

Anthony Aricia Teneza, 27, who faces robbery and elder abuse charges, was traveling in a stolen car with Nary Mey, 27, when they spotted the woman during the early morning of Aug. 13 at Pacific Avenue and Wood Street, police said.

Teneza and Mey were searching for vehicles to break into and the victim was on her way home after visiting the Cache Creek Casino Resort in unincorporated Brooks in Yolo County, Alameda police detective Wayland Gee said.

"There's no indication that the woman was followed," Gee said. "It was dark out, and the suspects saw the victim. There was an opportunity to rob her."

Mey, who stands 5 feet 3 inches and weighs 250 pounds, exited the car and approached the woman, knocked her down and stole her purse, police said. The victim was not hurt.

Police did not disclose how much money was in the purse. Mey was arrested Sept. 19 after police received a tip that she was possibly involved in the mugging. Teneza was then identified and interviewed at Santa Rita Jail, where he was being held in connection with another case.

Teneza and Mey, who lives in Oakland, remain in custody at the jail. Mey is scheduled to be sentenced Nov. 30 at the Rene C. Davidson Courthouse in Oakland on a second-degree robbery charge. Teneza is set to be arraigned Thursday at the Wiley M. Manuel courthouse in Oakland.
