Everyone believed his sister-in-law took her own life — until her family uncovered the dark secret behind “perfect jockey” Johnny

In some ways Paula Mullan wants the inquest into her niece’s death to be over because she’s worried about the impact that the horrific details of Katie Simpson’s murder will have on Katie’s mother.
‘You’re going to have to listen to it all again,’ she says. ‘I worry about my sister Noeleen having to go through all that and my parents.’
As the oldest of her siblings, Paula is the one who speaks for the family as much as she can. But since showjumper Katie’s death in August 2020, life has never been the same for the Mullan family.
The initial trauma that this beautiful 21-year-old with everything to live for had taken her own life soon spiralled into a nightmare, during which the family tried in vain to get the Police Service of Northern Ireland to listen to their fears that she had in fact been murdered.
Had it not been for the courageous actions of a journalist, a police detective from a different jurisdiction and the concerns of a family friend, horse trainer Jonathan Creswell – the partner of Katie’s eldest sister Christina – would have got away with murder.
Creswell battered, raped and strangled Katie, then pretended she had hanged herself from the bannisters of the home she shared with Creswell and her sister, their children and another woman from the horsey set, Rose de Montmorency Wright. The women were all working with Creswell in a business along with his former girlfriend Jill Robinson.
He was a known abuser, having been convicted and jailed for serious assaults on his ex-girlfriend Abigail Lyle, but Paula says she knew nothing of Creswell’s past crimes when he was with her niece.
During his trial for Katie’s murder, the 36-year-old could see that the odds were stacked against him and while he was out on bail, he took his own life.
Later three women, who had also at some point been in sexual relationships with Creswell, were given suspended sentences for withholding information from police about the circumstances of Katie’s death.
Now Paula says she hopes the upcoming inquest will bring some kind of peace for the family, when it finally happens.
She is frustrated that it is taking this long.
