THIS is the haunting moment a killer screamed “I warned you” as he was arrested for stabbing a gran to death in a random slaughter.
Cameron Davis, 31, was seen loitering in Ludwell Valley Park in Devon as he hunted for a stranger to attack.
The killer then pounced on 74-year-old Lorna England as she walked home from Lidl – knifing her in the neck and chest.
Dramatic footage has now been released of the moment Davis screamed: “She didn’t die – please tell me she didn’t die?”
He then repeatedly yells “I warned you, I warned you” to officers as they pin him to the ground.
Davis admitted manslaughter by diminished responsibility but was today convicted of murder.
Exeter Crown Court was told how leading up to the killing, he was living in temporary accommodation provided by a housing association.
On January 23 last year, Davis demanded he speak to support workers claiming his mental health was deteriorating and that he would “kill a random”.
Between February 9 and 16, the killer was seen by a mental health team who decided he did not need to be sectioned.
Two days later, video captured Davis walking out of A&E before buying two bottles of vodka and a kitchen knife from a supermarket.
Lorna meanwhile was seen leaving the same supermarket on her way home with flour for her husband of 52 years.
Tragically, the pair’s paths crossed as Lorna entered the park where Davis was lying in wait for a victim.
The killer then fled the scene and went drinking in a pub during a five-hour manhunt.
He was eventually arrested by armed police where he yelled out: “I f***** warned you c****, that’s why I f****** done it.
“I didn’t want to but none of you f****** c**** listened.”
After he was taken into custody, Davis claimed the “people at the hospital should pay”.
But during his trial, jurors were told the killer stabbed Lorna because he was “angry and upset” rather than affected by a mental illness to a level that his responsibility was diminished.
Davis was remanded into custody to be sentenced on Thursday.
Senior Investigating Officer Detective Inspector Dave Egan from the Major Crime Investigation Team said: “This was a brutal assault on an innocent woman. For reasons known only to Davis, he launched this unprovoked attack on Lorna as she walked home on a Saturday afternoon.
“His pleas to manslaughter were not accepted by the team and we are pleased that the jury reached this verdict today. Davis has had several psychiatric reports, two of which failed to support that he was suffering from mental health-related psychosis, a defence he claimed.
“In reality, Davis went out that afternoon intent on causing someone harm.
“Our belief is that it could have been anyone that he attacked that day – but tragically for Lorna, and all who knew and loved her, it was her that he chose and only he will ever truly know the reason why.”
