Lee Tipping, 37, subjected husband and wife Patricia Livesey, 56, and Anthony Tipping, 60, to “savage and extreme” violence in their own home.

A court heard Tipping stabbed his dad at least 131 times before turning the knife on his frail mum and inflicting at least 153 stab and slash wounds to her six-stone body.

He even washed the kitchen knife afterwards, and put it in his father’s lifeless hand.

Tipping was sentenced to life in jail today with a minimum of 27 years

The killer showed no emotion as he was led to the cells to begin his sentence

The jury had heard how Tipping lost control in the family home in High Walton, Lancashire, and “hacked” his parents to death in November 2021.

It happened after a row about a broken door and Tipping’s failure to take medication.

But many of Anthony Tipping’s 131 knife wounds – including “unusual” injuries to the dad’s eyes and genitals, were caused after death.

The killer left the bodies to fester as he fled to Manchester Airport in an attempt to leave the country, but panicked when he saw armed police and tried to check into a Premier Inn in Manchester city centre.
