The former police captain, 71-year-old Curtis Reeves, has been charged with second-degree murder. It wasn't immediately clear whether he has retained an attorney.
Pasco County Sheriff's officials said the shooting happened Monday when Reeves asked 43-year-old Chad Oulson to stop texting at the theater in Wesley Chapel, a suburb about a half hour north of downtown Tampa.
Charles Cummings, who was in the theater and witnessed the shooting says Reeves and his wife were sitting behind Oulson and his wife. Oulson told Reeves he was texting with his 3-year-old daughter.
