Kellon Hill was struck on the head with helmets and a cane, forcing him to fall to the ground twice as he bled profusely from his stomach, a witness recounted.

Natasha Morris told a Supreme Court jury she saw a group beating up Mr. Hill but couldn't be sure who it was because it was dark.

Miss Morris explained she was at the party that night with two friends when she heard a fight break out.

"I heard something like a helmet hit the ground so I turned around and I saw everybody running so I followed. I saw Zharrin and Kellan and the other Kellon who was fighting and trying to defend himself.

"I saw Kellon drop to the ground and he got back up and I saw somebody else hit him with a cane and then he stumbled towards where I was standing and then he dropped to the ground at my feet," she said.

The Berkeley Institute student told the court Mr. Hill fell down backwards and she only saw the blood the second time he fell because he was right in front of her.

She said when he fell, he hit his head on the ground and was bleeding on his right side by his stomach.

Miss Morris said she doesn't know where the attackers went because everyone had crowded around Mr. Hill.

During cross-examination, Miss Morris admitted after looking at her witness statement that she had told officers there were 10 to 15 youths hitting Mr. Hill on the head.

In court yesterday she said there were five to seven attackers.

After being pressed by Hairston's lawyer, Jerome Lynch QC, Miss Morris said she said five or seven people because she realised it afterwards. She agreed she didn't tell Police.

Miss Morris further admitted she said there were five to seven attackers because there were five people in the dock.

Jean Diondea Symons took the stand late yesterday afternoon and told the court he was with his cousin Kellon when they decided to go to the party.

"We were just sitting around talking and then we decided to leave and that is when ya boy Gary hailed we guys up, and Kellan Lewis came and snatched his chain."

Mr. Symons explained to the court that hailing means touching fist to fist.

He described Mr. Hill's chain as long and gold, with a Jesus pendant on it.

He said his cousin ran down towards the guys and asked for his chain back but Lewis refused to give it to him.

Mr. Symons said he grabbed Hollis and asked him, "What are you doing?" but let him go when he saw someone come out of the crowd with a cane.

Kellan Jeaurreau Lewis, 17, Kevin Andre Warner, 19, Gary Rupert Hollis, 16, Devon Vonzel Hairston, 18, and Zharrin Frankie Simmons, 17 pleaded not guilty to murder at the start of the trial.

Lewis alone is accused of unlawfully possessing a bladed article in a public place, with the others facing individual charges of possessing offensive weapons. Warner is said to have had a wooden cane, Hollis and Hairston allegedly had crash helmets, and Simmons a screwdriver.

They deny all the charges.

Mr. Hill was allegedly stabbed to death as he left a late-night party at Elbow Beach last August.

The trial continues.
