SAN FRANCISCO, CA — A suspended San Francisco police officer who is accused of bank robbery pleaded not guilty in federal court on Friday. He remains in custody.

Rain Daugherty, 44, of San Francisco, was arrested on Tuesday on a federal criminal charge of robbing a bank in the Sunset District of the city of $9,050 on Nov. 29. Daugherty is also one of nine officers facing Police Department administrative charges of sending racist text messages and additionally has been accused of elder abuse and drug possession in an unrelated criminal case in San Mateo County Superior Court.

San Mateo County District Attorney Steven Wagstaffe said that in the Peninsula case, Daugherty is accused of stealing $13,095 from a 76-year-old man with Alzheimer's disease between Sept. 1 and Dec. 1, 2017. Daugherty had been hired to do errands such as grocery shopping and driving for the man, Wagstaffe said. After getting a tip from a family friend, an investigation allegedly found that surveillance tapes showed that Daugherty used the man's ATM card while alone on 30 occasions to withdraw a total of $13,095, according to Wagstaffe.

A search of Daugherty's residence on Dec. 1 found small amounts of cocaine and three other drugs, Wagstaffe said. Daugherty was charged on July 24 with one felony count of elder abuse and four misdemeanor counts of drug possession. He could be sentenced to up to five years in state prison if convicted, the district attorney said.

Daugherty will have a preliminary hearing on those charges in San Mateo County Superior Court on Feb. 1.

Wagstaffe said he could not comment specifically on Daugherty's case, but said of elder abuse in general, "It's an evil act."
