Police say a father and son were behind the horrifying mass shooting that left 16 people dead, including one of the gunmen, and 40 people hospitalized during a Hanukkah celebration at Bondi Beach in Sydney, Australia. New South Wales Police Commissioner Mal Lanyon said during a press conference on Monday in Australia that it was a 50-year-old man and his 24-year-old son that carried out the terror attack. The father is dead, police said, and the son is in critical but stable condition in a hospital. Lanyon also said they are not looking for additional suspects at this time.
