A POLICE reconstruction video shows the key locations in the events which led to the death of Olly Stephens.

The five-minute clip walks through key areas in Bugs Bottom which were all mentioned during the six-week trial of the teenagers accused of murdering the 13-year-old in January 2021.

Following 18 hours of jury deliberations, both boys were found guilty of murdering Olly Stephens.

The video -- played to the jury during the trial -- has now been released to the press following the verdict and it begins at the entrance of Bugs Bottom.

The first image seen is the bench at the south entrance of the park.

Ms Natasha Grant -- a witness called into court on Friday, July 2 -- said she had been walking in Bugs Bottom on January 3 with a friend and her children when she noticed two youngsters walking towards the bench she was sitting at.

She claimed she heard one of them say “they [the other group of teenagers] are at the other bench.”

The boys were then joined by two other boys, who prosecutor Denis Barry claimed were the defendants.

Ms Grant said these two boys were “trying not to draw attention to themselves” as their faces were “really covered.”

The video then takes a birds-eye-view of Bugs Bottom and locates the other bench on the hill.

This drone footage was recorded in the days following Olly’s death and police officers can be seen patrolling the area.

It is the bench on the hill where Olly had met the girl who has admitted to his manslaughter and another boy, who later rushed to Olly’s house to alert his family he had been stabbed.

A group of boys including the two defendants -- described as ‘two angry boys’ by prosecutor Alison Morgan QC -- ‘went up the hill armed with a knife.

‘They went to ambush him [Olly Stephens].’

Upon approaching Olly, the girl and the boy near the bench, the younger defendant confronted him about ‘snaking’ them.

Olly told him to ‘f*** off’ before he started having a fist-fight with the older boy.

According to eyewitness Zoe Neville, ‘four or five’ punches were thrown by the boys and it seemed like a ‘fair fight’.

However, the younger boy intervened when he said it appeared Olly was ‘getting the better’ of the older boy.

According to the boy, he stabbed him supposedly aiming for his arm. The older boy, on the other hand, said he saw his co-defendant launch out at Olly and stab him in the stomach.

But pathological reports showed to the jury indicated Olly was stabbed in the chest.

A second stab wound, on Olly’s back, was apparently inflicted when he fell onto the younger boy who had been holding the knife having been pushed.

The older boy claimed his co-defendant deliberately reached around to stab Olly a second time in the back, however.

Zoe Neville, the eyewitness, did not see the stabbing but did hear a metallic ‘clink’ sound.

Having seen the first part of the fight, she only saw the boys and the girl scattering after the stabbing.

Olly was ‘staggering’ towards Ms Neville following the altercation and despite resisting help initially, according to the prosecution, eventually collapsed.

Ms Neville, a trained cardiac nurse, started giving him CPR (at the location shown on the video) while simultaneously speaking to emergency services on the phone.

The call was recorded at 3.46pm -- just 12 minutes after Olly had left his house to go to Bugs Bottom.

The other boy at the top of the hill with Olly had rushed to his home address to tell his parents he had been injured.

By this point, the two defendants had fled down the hill on the younger boy’s e-scooter.

The video shows Hemdean Road. The boys were spotted on the e-scooter by a resident at 3.48pm.

One eyewitness claimed they heard the older boy say ‘Man I need your advice, I need your advice’ to someone on the phone as they fled.

Emergency services rushed to Bugs Bottom to assist Olly Stephens.

Olly was said to be unresponsive and not breathing when they arrived, with blood coming out of his mouth.

Paramedics tried to treat him for 30 minutes before he was moved to an ambulance.

A specialist consultant arrived at the scene and emergency surgery was carried out in the ambulance.

However, Olly did not show signs of recovery and it was decided treatment would stop. He was declared dead at 1700 hours on January 3, 2021.

By this point, the boys had split up with the younger teenager returning home and the older teenager visiting friends in Reading town centre.

They would later reconvene at Palmer Park in the evening at around 7pm where the younger boy would discard his bloodied clothes.

The older boy handed himself in to police just after midnight on January 4, 2021, before the younger boy was arrested at his house more than an hour later.
