A construction worker turned triple murderer when he killed his 24-day-old daughter, 21-month-old son and new partner.
Jordan Monaghan smothered his three-week-old daughter, Ruby, on New Year’s Day 2013.
The 30-year-old, a manipulative and controlling gambling addict, then went on to kill his 21-month-old son the same way at a swimming pool eight months later.
While on bail for the child murders in October 2019 he killed his new partner Evie Adams, 23, by giving her a cocktail of deadly prescription drugs he had bought on the black market.
The father was handed three mandatory life sentences and ordered to serve a minimum of 40 years behind bars after being found guilty of murdering his children and partner and the attempted murder of a third child.
At his trial it was revealed the Monaghan revelled in the attention and sympathy after the "tragic" sudden deaths of his two young children.
He spoke to reporters of his “heartbreak” and posed for photos with the children’s grieving mother.
Monaghan, from Blackburn, even vowed to undergo genetic testing to see if an underlying health condition was responsible for the children’s deaths.
