A man who fed heroin to his baby daughter through a syringe into her mouth to get back at his ex-girlfriend has died in prison.
UK man Roger Weir was jailed for 18 years in 2012 after attempting to murder his ex with a meat cleaver and a boat flare.
After he was unsuccessful in his murder attempt, he sought revenge by squirting heroin into his own daughter's mouth.
The ex-girlfriend then ran for her life and called police, who then took the baby off Weir, who is a self-confessed "psycho".
After the attack on his ex and his abusive act on his baby daughter, Weir told the court "voices" in his head were to blame for the attack.
