Police will allege he killed the three people, Homicide Detective Superintendent Danny Doherty said on Wednesday, stabbing the man after earlier assaulting the woman and the child with “murderous intent”.
Doherty sought further help from the public and encouraged anyone in the vicinity of the taekwondo studio on Monday night who may have seen or heard something to contact investigators.
