A medical expert has told the Hillsborough inquests he thought a Chester teenager was already dead when a photo showed him being given mouth-to-mouth on the pitch.

Former Queens Park High School student Henry Rogers from Dodleston was shown on footage at 3.20pm in the pile of casualties at the front of pen three during the crush on April 15, 1989.

Medical expert Professor Jerry Nolan told the inquests that Henry, 17, looked motionless in the pile and it was likely his heart had stopped beating by then, but he could not be certain.

He said he thought Henry, who was given CPR in the pen and at the Spion Kop end of the pitch, was dead by 3.35pm when a photo showed him being given mouth-to-mouth on the pitch.

He said: “We have probably two resuscitation attempts without any documented response. We have got no clear indication of any signs of life during that timeframe.”

In September, the inquests heard that Henry's parents were contacted by fans John Owen and David Roland who told them their son had died in Mr Owen’s arms.

But, Mr Owen told the inquests that he no longer believed that was the case.

In a statement he made in 1989 , he said: “The next thing I remember was that I was in the six yard box near the goal when I tripped over a foot.

“I looked down and I saw a young lad lying on his back with his right knee in the air and his hand was in the air as well.

“I grabbed his hand and I knelt down beside him. I took his hand and asked him if he was alright. I lifted his head up. I think he was still alive then but he didn’t say anything.”

He added: “I saw his eyes roll back and he died in my arms.

“I later saw a picture in the Liverpool ECHO newspaper of this boy and his name is Henry Charles Rogers . I held him for about two minutes when a policeman told me to leave him.”

But he said, after experiencing flashbacks five years after the disaster , he believed he helped two casualties on the day and the boy who died in his arms was not Henry.

He confirmed he had visited Henry’s parents, Stephen and Veronica, on April 20, 1989, and told them Henry was not alone when he died.

But he said he no longer believed that the account he gave them was correct.

He told the court: “The accounts I gave first were probably quite rushed and quite hazy."
