A thug who strangled a woman in a vicious assault killed his own dad 17 years ago in an attack so severe that doctors found more than 100 injuries across his body.
David Alty was jailed last week after launching an attack on a family friend who gave him a place to stay.
Alty, now 36, was heavily drunk and in the midst of a psychotic episode when he punched the woman before strangling her and telling her he was going to kill her at her home in Litherland earlier this year.
