Describing the day Jaydon was found, she said: “We all died that day.”
Diego Henry and Jaydon Beckford were good friends, the inquest heard, and it was said there was no animosity between them.
On 5 November, the pair had been with another friend at Jaydon’s home in Lighthorne Avenue.
In a statement read to the inquest, Jaydon’s mother Leah Hussain said she heard laughing and chatting before she fell asleep.
She was later woken by a bang at about 12:30 GMT, which she initially thought may have been a neighbour setting off a firework until she heard the other friend shout “phone an ambulance”.
The hearing was told Jaydon was then seen on CCTV running with his hand in his right pocket, towards the city’s canal system, away from the city.
He was then found dead on the 10 November. While it cannot be confirmed, it is believed the same gun was used.
The third friend was bailed over Diego’s death and was not arrested in connection to Jaydon’s.
He also told police what happened to Diego was an accident and he was “not in custody, control or possession of the firearm”.
The inquest heard how the gun may have been given to Jaydon by “elders” for protection.
On Monday, Det Sgt David Newson of West Midlands Police, told the inquest into Diego’s death that the “working hypothesis was that it was accidental discharge”.
Diego died in hospital from a bullet wound to his head.
