A jury at Manchester Crown Court found him guilty of the murder of Olivia, the attempted murder of Nee, wounding with intent to do grievous bodily harm to Ms Korbel, and two counts of possession of a firearm with intent to endanger life.

Ms Korbel said she was “ecstatic” as she left court following the conclusion of the trial.

There were gasps and tears from Olivia’s family, including her mother who wore a pink cardigan and clutched a teddy, as the verdicts were returned.

Cashman wiped away tears in the dock and turned to his family in the public gallery behind, shaking his head.

One of Cashman’s relatives could be heard saying “appeal it” and they left the courtroom shouting and swearing.

The jury, of 10 men and two women, took nine hours and three minutes to reach their verdicts.

During the trial, which lasted more than three weeks, the jury heard the schoolgirl ran downstairs after hearing shots outside, saying “I’m scared mummy, I’m scared”.

The bullet which killed Olivia was fired through the front door, hitting Ms Korbel in the hand before striking the schoolgirl in the chest.

Nee, a 36-year-old with a number of previous convictions, was injured before he ran towards the house after three shots were fired from a self-loading pistol in the street on Kingsheath Avenue.

The gunman fired a further two shots from a revolver into the Korbel family home, one which killed Olivia and the other which became lodged in the door.

He then fled the scene, running across back gardens.

Cashman, a father-of-two, said around the time of the shooting he had been at a friend’s house where he counted £10,000 in cash and smoked a spliff.

During his evidence, he told the court: “I’m not a killer, I’m a dad.”

But a woman who had a fling with Cashman told the jury he came to her house after the shooting, where he changed his clothes and she heard him say he had “done Joey”.

Cashman told the court she was a “woman scorned” and accused her of lying because she wanted to “ruin” his life.

Merseyside Police senior investigating officer Detective Superintendent Mark Baker said: “When he (Cashman) found out that he had shot an innocent young girl, he should have had the courage to stand up and come forward.

“Instead, he chose to lie low despite the fact that he was a dad himself.

“He is not worthy of walking the streets of Merseyside, and neither are those who think they can bring fear or intimidation to our communities through use of firearms.”

Cashman is expected to be sentenced on Monday.
