New Orleans officials say one of the men they called a person of interest in the murder and shooting on Bourbon Street is in police custody. "Justin Odom (above) turned himself in to Gretna Police this afternoon," City Spokesman Tyler Gamble said in an email. "NOPD homicide detectives interviewed Odom with his attorney present." Cops have arrested the 20-year-old, but not for any charges linked to the shooting that left one bystander dead and nine more wounded. "Following the interview, Odom was arrested and booked on unrelated warrants in Jefferson Parish--outstanding traffic attachments and a shoplifting warrant." Police also said Wednesday that they hoped Odom could lead them to a second person of interest named Joe or Josh.
