Partrico Rodriguez, a 23-year-old Camden resident, surrendered to authorities Saturday morning, shortly after the shooting occurred. It was not known if he has retained a lawyer.
The incident happened in the 700 block of Broadway Street.
Camden County Prosecutor Warren Faulk says Rodriguez broke into the apartment around 3:45 a.m. Saturday and shot 30-year-old Lateaf Anderson "multiple times." The Sicklerville man was pronounced dead a short time later.
The former girlfriend was not injured in the shooting.
