The paparazzo, Brad Diaz, was hit in the leg Saturday night outside a Malibu home where he was tracking a baby shower for Spears, authorities say.
Diaz claimed the shot came from the direction of the home, Knudson said. Spears's bodyguards told authorities they weren't involved in the incident. A detective will be assigned to the case Monday, authorities said.
Smith initially said the home belonged to Spears, but said deputies later learned that it belonged to someone else and that Spears is a frequent guest. He did not identify the owner.
There has been no comment from the Spears camp, but a photo of the shower in Monday's New York Daily News shows a smiling Spears among such guests as her mother Lynne, sister Jamie Lynn and, according to the photo caption, hubby Kevin Federline's two young children from his previous relationship with Shar Jackson.
