A jury convicted a San Francisco police officer Monday (4-15) of forced copulation and kidnapping by use of police authority but acquitted him of aggravated kidnapping for the purpose of rape. Francis Hogue faces up to 11 years in state prison and will be sentenced May 6. On March 18, 1994, the employee of a South of Market massage spa said, Hogue took drove the woman to a secluded spot and told her she would not be arrested for an earlier misdemeanor warrant if she had sex with him. She said Hogue then forced himself on her. Hogue’s lawyer said he will appeal the decision in a trial that weighed heavily on DNA analysis.
