A love triangle and two specks of gunpowder on a pair of Under Armour tracksuit bottoms helped to prove that Thomas Cashman was the man who shot Olivia Pratt-Korbel dead.
The 34-year-old, of Grenadier Drive in West Derby, was jailed for life with a minimum term of 42 years this week after being unanimously found guilty of the schoolgirl's murder. She was killed aged nine in her own home on Kingsheath Avenue in Dovecot on the evening of August 22 last year.
One of the key pieces of evidence in the trial was the testimony of a woman whom Cashman had previously had a sexual relationship, behind the back of his long-term partner Kayleeanne Sweeney. This witness cannot be identified for legal reasons, but she reported to the police that the killer appeared by her bedside following the shooting before making an apparent confession.
