A DRUG dealer who was shot dead fell out with his ex-gangster stepfather over plans for his mum to move into a Plumstead "sex dungeon", the Old Bailey heard today.

Genson Courtney, 23, was shot in the eye in Banning Street, Greenwich, in July 2011.

His uncle David Pinto, aged 33, of Tyler Street, Greenwich, and alleged accomplice Robert Bleach, aged 45, of Halstow Road, Greenwich, both deny murdering him over a debt.

In the fortnight before his death, the cannabis dealer, who was taking steroids to help his body building, had lived an erratic lifestyle, robbing other dealers and brawling with stepfather Dave Courtney on Plumstead Common, the court was told.

In a statement read out in court, Mr Courtney said time in prison and a decline in after-dinner speeches meant he had fallen behind on mortgage payments for his home in Plumstead called Camelot.

He claimed a backup plan to move his wife Jennifer Pinto into a property at the back of his house had made his stepson angry.

He said: "Genson told me to get my knuckle duster. I think, because I told him I didn't need my duster he may have thought I was standing up to him."

The pair ended up on Plumstead Common, where Genson was "bouncing around" before punching his stepfather three times.

Mr Courtney said: "I said to Genson 'hold it'.

"I had both my hands up and said 'let's call it a draw'."

He claimed the pair made up days later with a "man hug".

Giving evidence today, the victim's mother Jennifer Pinto tearfully said her son had become enraged because the property at the back of Dave Courtney's house was actually a "sex dungeon".

She claimed her husband preferred to keep her at home with his hangers-on, who she branded "courtneyites", rather than let her help Genson with his decorating.

Recalling the night she found out her son had been shot, she said: "I was going to pick him up, take him to hospital, probably give him a speech on the way there to say 'calm down Genson'."

When she arrived at the scene, a police cordon was already up. At hospital her son's life support machine was switched off hours later.

The trial continues.
