NEW ORLEANS (AP) " New Orleans prosecutors say a 27-year-old man has been convicted of sexually assaulting an 8-year-old girl in her grandmother's house.

District Attorney Leon Cannizzaro's office says Alfred Ravy was convicted Thursday of sexual battery against a juvenile under age 13 and of indecent behavior with a juvenile under age 13.

The crimes carry total minimum sentences of 27 years, and up to 50 years.

A news release Thursday said the girl and an uncle were in her grandmother's house when Ravy stopped by. It says he excused himself from a conversation with the uncle, saying he was going to the bathroom, but instead went into the girl's bedroom and assaulted her.

The girl told her grandmother, her mother, and then a forensic interview. Ravy was arrested days later.
