SACRAMENTO (CBS13) — Investigators believe there may be more victims of a doctor who is charged with raping a patient.

Dr. Logan Ford is smiling in his mugshot, but he faces felony charges of rape, sexual assault and sexual exploitation by a physician.

“We have that trust in our medical professionals..and this was violated obviously by this subject,” said Sacramento County Sheriff’s Lt. Lisa Bowman.

Investigators say it happened at the 420 Medical Marijuana Evaluation Center off of Watt Avenue, where Ford works.

“During the patient’s exam, it was actually at the facility she was sexually assaulted; she was raped,” Bowman said of the alleged March incident.

Ford also works as a physician at medical-marijuana facilities in Berkeley and Oakland.

“We don’t believe this is an isolated event,” Bowman said. “We believe that likely, due to the business that he practiced and this actually happened during a medical exam..this may have happened before.”

According to Ford’s attorney and records from the State Medical Board of California, he has experience as a doctor and a surgeon. He received his undergraduate degree from Stanford University and his graduate degree from Howard University College of Medicine.

He has no prior record of discipline.

Chi Chang came to the clinic on Wednesday for an evaluation, but changed his mind after he heard about the allegations.

“I think I’m just going to change my mind and just go somewhere else,” he said.

Ford’s bail is set at $1 million. He’s expected in court on Friday.
