Ordinary household item linked to gruesome maternal incident

In a chilling case that has gripped the nation, a man stands accused of committing an unthinkable act of violence against his mother, using an ordinary household item as a lethal weapon.

The incident, which occurred in the quiet NSW Central Coast suburb of Tumbi Umbi, has left the community in shock and sparked a conversation about the devastating impact of addiction and mental health issues.


David Andrew Mapp, a 59-year-old man, is facing the NSW Supreme Court, charged with the murder of his 82-year-old mother, Coleen Wilson, on 28 July 2022.

The prosecution alleges that Mapp, in a horrific turn of events, used a pot plant to fatally bash his mother during a heated argument.

The case has taken a dark turn as further details emerged, revealing that Mapp allegedly pawned his mother's belongings to purchase heroin after her death.

Crown prosecutor Carl Young described this act, which was captured on CCTV.

The footage shows Mapp exchanging a TV and hedge trimmer for $200 in cash.

The court heard that on the morning of the incident, an argument ensued between Mapp and his mother, which escalated to the point where Mapp went outside, grabbed a pot plant, and assaulted Ms Wilson with it, striking her in the back of the head.


The blow caused her to fall to the ground, and it is alleged that Mapp then applied pressure to her neck while she lay there, a claim that the defence disputes.

In a tragic twist, Mapp's barrister, Sarah Talbert, painted a picture of a man struggling with a lifetime of heroin addiction, having used the drug since he was 16, and who was heavily reliant on his mother for support.

This dependency, Talbert suggested, led to a relationship fraught with tension, anger, and frustration.

The defence is set to argue that Mapp's actions, while admittedly resulting in his mother's death, were not carried out to kill.

Instead, they will present evidence that Mapp was suffering from severe heroin withdrawals and a generalised anxiety disorder at the time, which they claim impaired his judgment and self-control.


In a distressing 000 call made by Mapp at approximately 5 pm on the day of the death, he reported the body and described a 'bad argument' that had escalated.

He claimed that his mother had been chasing him with a knife and that, in response, he had thrown the pot plant at her.

Mapp also told the operator that he had been attempting CPR all day in a desperate attempt to revive his mother.

Ah! Let's watch this guy get away with murder, due to mental health issues and drugs. No mum should live in fear of her life because of her own kids.
The poor mother she must have been living on a knifes edge and had probably refused to give him money which she most likely didn't have. Her son should be locked up in a prison hospital till he is cured of his addiction and then tried for murder after all if they put him a normal prison he will still be able to get drugs from wardens.
 
Murder is murder, doesn't matter what the circumstances that led up to it are or what illness the person may be suffering from. At the end of the day a person who commits any kind of crime is the only person responsible for their actions and should be jailed for till death takes their life.
And as for an 82yr old chasing him with a knife, damn she would have to have still been quite sprite for her age. Most people I know in their 80's if they aren't using canes or walkers, certainly aren't able to run after someone let alone while banishing a knife. They'd be too worried about their bodies failing them and that they'd fall and land on the knife instead.
 
I find all these claims now of 'mental health' being offered as an excuse for too many violations and given lesser sentences.
I believe the acts committed are already in the thoughts and psyche of the person, and the crime is responsible for the release of psychotic or other substances, others with previously recognised mental disorders.
Murder is murder.
Acts of violence are present in the person's conscious thoughts, not always carried out but still present.
