A witness told a Supreme Court jury he saw one of the defendants accused of murdering Kellon Hill with a screwdriver in her hand at the party where the teenager was killed.

Yesterday the court heard from Shae Johnson, a friend of Mr. Hill's, who was at the party and saw the alleged attack.

He told the court he saw Zharrin Frankie Simmons, 17, holding what looked like a screwdriver with a red and black handle.

"I saw a screwdriver. I can't recall what hand it was in. I just saw the handle. I said it was a screwdriver because of the look of the handle."

"I saw it in her hand when she turned around to walk off."

Mr. Johnson said he didn't know what happened to the screwdriver after he saw Simmons with it.

Kellan Jeaurreau Lewis, 17, Kevin Andre Warner, 19, Gary Rupert Hollis, 16, Devon Vonzel Hairston, 18, and Simmons have denied murdering Mr. Hill.

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.

The 18-year-old was allegedly stabbed to death as he left the late-night party at Elbow Beach last August.

Asked how he knew the defendants, Mr. Johnson said he went to school with Hairston and didn't know the others aside from their names.

Mr. Johnson said he arrived at the party around 10.30 p.m. on August 9 and talked to a few friends.

"I spoke to Devon. He walked across me. We put fists together and he kept going somewhere else.

"I saw Kellan Lewis walking around shouting stuff. I saw Zharrin drinking. It was a bottle like an Arbour Mist bottle. She was the only one drinking."

Mr. Johnson told the court Simmons and Lewis were disturbing people in the area, upsetting them. They were asked to stop their behaviour but continued.

Asked about an alleged fight said to have caused Mr. Hill's death, Mr. Johnson said: "I recall leaning on the wall and somebody said a fight broke out so my attention went that way."

He added it happened by a telephone pole that kept flickering on and off.

"I couldn't do anything. I was in a state where I could only watch. I saw a helmet swing and a cane and a fist fight."

Prosector Michael McColm said: "At that stage, can you tell us who was involved?"

Mr. Johnson said Hollison, Lewis and Mr. Hill.

"I saw Gary swing a helmet overhead. I saw him do it twice. It hit Kellon Hill. He was cornered in a fence."

Mr. Johnson said the Bermuda Institute graduate was hit in his chest area and tried to fight back.

"I saw Kellan Lewis hit him. He was fighting back, swinging his fists. The swings made contact on his face. A cane was broken across Kellon Hill's head."

Mr. McColm asked the witness if he saw who had the cane and Mr. Johnson said it was Warner.

Asked where Simmons was at this stage of the fight, Mr. Johnson said she came through the crowd with fist motions.

"Kellon Hill was still trying to fight them off and then he went towards the exit and then he fell to the ground and he got back up and somebody helped him to the side and he was just lying on the ground and somebody shouted 'he got stabbed'."

He said the defendants, along with about 50 other people, ran down the hill to the beach after Mr. Hill fell the second time.

During cross-examination, Lewis' lawyer, John Perry QC, suggested to Mr. Johnson that there was no fight and he couldn't have seen a fight because it was dark.

Mr. Johnson disagreed.

The trial continues before Puisne Judge Charles-Etta Simmons.
