An Austin Fire Department arson investigator has been charged with four crimes — sexual assault, another felony and two misdemeanors — and was booked Wednesday into the Travis County Jail, according to court records. Lt. Marcus Reed is accused of using his position as a law enforcement officer to lure a woman into his city-owned truck in March and assaulting her. Reed faces life in prison for the sexual assault charge. He also faces a felony charge of misuse of official information, and a grand jury has indicted him on misdemeanor charges of abuse of official capacity and official oppression. Fire Chief Rhoda Mae Kerr said in a statement Wednesday that she would be suspending Reed without pay at 9 a.m. Thursday.
