From the information given, Darron Coster's death would appear to have been officially announced by the chairman of the enquiry, Sir John Saunders, and this is what prompts the subsequent news articles about his death.
BBC report of 19 July 2021:
Manchester Arena bomb hero Darron Coster dies in crash
https://www.bbc.co.uk/news/uk-england-l ... e-57889441
An ex-military police officer hailed a hero for helping Manchester Arena bomb victims has died in a road crash.
Darron Coster was praised for his actions after giving evidence to the Manchester Arena Inquiry in April.
Addressing the inquiry, chairman Sir John Saunders said Mr Coster, from Accrington, died "following a road traffic collision" on 14 July [2021].
He said he did an "amazing job" treating casualties after the bombing and his heroics would "live on".
Mr Coster, who retired from the Royal Military Police in 2008 and was in his 50s, was waiting to pick up his son when the explosion happened on 22 May 2017.
The attack killed 22 people and injured hundreds more.
Opening a hearing of the inquiry earlier, Sir John said Mr Coster's death was "very sad news".
He did not give any other details of the crash.
He said Mr Coster, who told the inquiry in April that he used his Royal Military Police training to assist in the "carnage", was a "hero" for what he did on the night of the attack.
"Because of his training in Northern Ireland, he had experienced explosions in the past," he said.
"He knew how to help those who had suffered blast injuries [and] applied improvised tourniquets to some of the more seriously injured."
It doesn't state it in that article, but Darron Coster apparently worked for the RMP for 22 years, retiring in 2008. Richard Hall only shows a section of his testimony with regards to armed police being on the scene within the first ten minutes. But there is some other interesting testimony.
This is from The Scottish Sun, 28 May 2017, six days after the alleged suicide bomb.
Heroic dad describes seeing Manchester suicide bomber’s body as he rushed to give first aid to victims

The former Royal Military Police staff sergeant calmly walked INSIDE the arena as survivors were fleeing to give first aid.
Lorry driver Darron helped dozens of shocked and bloody survivors before paramedics and police reached the scene.
Speaking to The Sun on Sunday he said: “”My son was at the concert with his girlfriend and a mate. I arranged to meet him at railway platform at bottom of stairs to the arena.
“I was only there a minute and it went “bang”. I knew I had to find my son.I walked up the steps until I got right into where it happened.
“It was pandemonium. It was seconds after the bomb went off. I was in military police for 22 years so my training kicked in and I took control of stuff.
“All these people milling around not knowing what to do. No one is prepared for this.
“So I said ‘there’s a lot of people dead, forget about them there’s nothing you can do, find someone who is moving.
“I sort of guessed it was a suicide bombing. Then I tried to close the doors because I could see the suicide bomber’s body.
“I could see half of his body halfway inside. I went over and closed the doors because I didn’t want anyone seeing that.
“It looked like he had been blown inside the doors. I didn’t want to look. His torso was through the doors and he had no legs. I couldn’t see a rucksack.
“Some of the MEN staff came and I told them to get some water and within seconds they came back with lots of water.
“I took a load of it round. I saw the two homeless blokes and they didn’t know any first aid so made sure they went round talking to people who were conscious.
“I put a couple of tourniquets on people. There was a gentleman sat with wife who had internal injuries and I asked for his belt and I put in the lady next to him who had a leg injury.
“Someone else had a belt and I used that on someone else.
It continues, Coster says it took 15 to 20 minutes for the paramedics to arrive, and Richard stated the report says the first paramedic arrived at 22 minutes (in keeping with the whole 22 theme), but did not attend anyone at the scene, and two others arriving 44 minutes after (yes, add 44 get 66). One thing I notice from the apparent Sun quotes, the vocabulary doesn't seem to match the man being interviewed at the enquiry. From what I read in the Sun article and the lack of what is stated via the emergency services in Richard's film, Darron Coster would appear to have provided the bulk of the testimony regarding actual injuries being treated.
Going to have a little look into his death next.
