"The father said he was taking a shower when he heard a gunshot," Lt. Greg Baker with the St. John the Baptist Parish Sheriff's Office told CBS affiliate WWL-TV. "He got out of the shower, and that's when he discovered that his daughter had accidentally shot herself."

Detectives said the gun hadn't been securely stored.

However, Moore's neighbor told the Times-Picayune that the devoted father normally took gun safety very seriously.
