Media reports of a Russian Roulette shooting at Pitt Town on Friday aren't supported by current evidence, according to Hawkesbury police.

Police have told the Gazette that their evidence doesn't suggest that 19-year-old Josh Taylor was involved in a game of Russian Roulette.

Mr Taylor shot himself in the head on Friday about 6.30pm while sitting in the driver's seat of a blue Holden Commodore with his two friends outside the IGA supermarket on Eldon Street, Pitt Town.

Speculation and reports have spread stating that he and his friends were playing Russian Roulette which involves placing a single bullet in a revolver’s chamber and spinning the chamber before pulling the trigger, providing a one-in-six chance of being shot.

Hawkesbury Detective Inspector Garry Sims was the duty officer in charge on the night and believes Mr Taylor's friends had no knowledge of what was about to happen, contradicting current media coverage.

‘‘We believe it wasn't an organised action by all three of them,’’ Det.Insp. Sims said.

‘‘Mr Taylor produced the firearm without the other friends knowing or agreeing to it. 

‘‘We are not discounting or confirming the fact that he was involved in that game, we need more evidence to confirm the theory.’’

The Acacia Gardens resident suffered a single bullet wound to the right side of his head causing dramatic swelling.

Police have said that he is very lucky to have missed death.

The car he was in was parked in a prominent area near the shops and in between two other cars.

Emergency services and police officers rushed to the scene and blocked off the streets immediately.

Forensic examiners were taking lots of photos of the passenger seat, door and road nearby to put the pieces together of what happened.

Four paramedics spent around 20 minutes working to stabilise Mr Taylor in the back of the ambulance before he was taken to the paramedic helicopter which landed at a nearby park on Eldon Street.

He was airlifted to Westmead Hospital in a touch and go state and rushed to the Intensive Care Unit where he underwent surgery the next day to remove all bullet fragments from his skull.

He remains in a critical but stable condition with unconfirmed reports that he remains on life support.

Det. Insp. Sims said the occupants of the car are very lucky the bullet didn’t rebound off a surface and hit someone.

‘‘Police at this point don’t know what his motive was but will find out if and when he makes a recovery. Investigations for now will be complex and take a little longer due to his current state.

‘‘We face the prospect of him not remembering what happened on the night because of possible brain injury.

"It’s a tragic result of a foolish action.’’

Police have told the Gazette that his mother and sister have been with him in hospital.

Mr Taylor lives with his mother and sister.

Police are urging people to show consideration on social media and be aware of the distress of his family.

His case is being treated as an unfortunate incident and forensic examinations are being carried out to trace the history of the gun.
