RAOUL MOAT issued a chilling warning to the detectives hunting him: “I will keep killing police until I am dead.”

His vendetta against Northumbria Police was outlined in a 49- page hand-written letter in which he admitted: “I guess I’ve finally lost it”.

The 37-year-old fugitive described in detail the shooting of former girlfriend Samantha Stobbart and her boyfriend-of-oneweek, Chris Brown, early on Saturday and the moment he blasted PC David Rathband with a shotgun on Sunday.

The bodybuilder is thought to have written the letter the day after wounding the police officer.

In it, he said: “The public need not fear me, but the police should as I won’t stop till I’m dead.”

Moat wrote: “Last night, I called 999 and declared war on Northumbria Police before shooting an officer on the West End A69 roundabout in his T5.

“Rang again and told them they’re gonna pay for what they’ve done to me and Sam.

“I went straight, but they couldn’t let it go.”

Blaming the police for taking away his children, his freedom and Miss Stobbart, Moat apologised for hurting his former girlfriend and wrote: “I still love her despite everything, but my head is a mess right now and I know I’m too far gone to make much sense of it.

“I guess I’ve finally lost it.

“I’m not on the run, I will keep killing police until I am dead.

They’ve hunted me for years, now it’s my turn.”

Moat revealed he crouched under an open window for an hour-and-a-half early on Saturday, listening to Miss Stobbart and Mr Brown “mocking” him.

He wrote: “I could hear everything.

“If I was ever going to back down, listening to them stopped that.

“At 2.30am, they came out.

“I shot him in the chest and he ran off. Sam screamed and tried to stop me as I gave chase.”

Moat claimed he fired another round into Mr Brown’s head, then wounded Miss Stobbart, which he wrote would mean she could get “massive compensation” and scarring to remind her “not to ever do this to anyone again”.

The letter went on: “I looked around for anyone else to shoot, there was no one, looked back at Sam, went to shoot myself, then changed my mind.”

Moat described how his rages took over, writing: “It’s like The Hulk, it takes over and it’s more than anger and it happens only when I’m hurt, and this time I was really hurt.”

He added: “Sam was like no other and filled huge gaps in my life, and changed my view on life.

“All my life I wanted death, hence the reason I took risks, made the worst kind of enemies and behaved the way I did.

“But now I had different thoughts. I wanted my life with Sam.”
