A Florida Keys man was arrested on a charge of incest after he impregnated a relative, a Monroe County Sheriff's Office spokeswoman said.
Brandon Williams, 31, was arrested on the third-degree felony charge Monday.
Monroe County Sheriff's Office spokeswoman Becky Herrin said detectives discovered Williams repeatedly had sex with a teenage relative and had a child with her as a result.
Williams also faces a second-degree felony charge of underage sexual assault.
The identity of the relative was not released because of her age.
