‘Oh god’: Pot plant killer’s confession caught on video

A man will be sentenced next week after killing his elderly mother with a pot plant before his confession was caught on video.

EXCLUSIVE

A NSW man who confessed on tape to “throwing” a pot plant at his elderly mother during an argument and killing her will be sentenced for her murder next week.

David Andrew Mapp, 59, made the admission on bodycam footage once police arrived at the home at Tumbi Umbi on the NSW Central Coast in July 2022.

A jury found him guilty of her murder in October last year, with his sentence now set down for May 29, news.com.au can reveal.

The court heard how Mapp killed his mum, Colleen Wilson, before 10am on the morning of July 28, but waited hours to call an ambulance, telling police he “didn’t know what to do”.

In footage obtained by news.com.au ahead of his sentence, Mapp sits in the family living room with police, with his 82-year-old mum dead in the kitchen.

Mapp tells police she had threatened him with a knife, and he was trying to “protect himself”.

“She had her back to me, sweeping the floor,” he tells the officers.

“I just sort of lunged at her with the plant … just trying to protect myself.

“I didn’t know how hard I was throwing it, I was in the midst of arguing with mum.

“I guess there’s no other word but, I just threw it at her I guess. At the back of her head.”

“I know I should have rang the ambulance, but I just … just hoped she’d be all right.

News.com.au also obtained the triple-zero call Mapp eventually made at 5.15pm.

“I’d like to report a death,” Mapp said on the phone call.

“I’m at mum’s and we had a bad argument.

“To protect myself, I threw the pot plant at her, and there was no response after that.”

The operator asks if she is breathing or awake, to which Mapp says no.

“We were up half the night arguing and before that. Things got bad and it didn’t let up and, and I didn’t know what to do. I did try to revive her,” he tells the operator.

The courts previously heard how after Ms Wilson’s death, Mapp was seen on CCTV pawning her television and whipper snipper for $200, which he used to buy heroin.

His lawyer had previously argued Mapp was in heroin withdrawal at the time and did not intend to murder her in an attempt to have the charge reduced to manslaughter.

Mapp suffered long-term heroin addiction after first being given the drug at age 12.

He will be sentenced for the murder on May 29.
