Teenager Kellon Hill was stabbed and beaten, then left to die when his attackers ran from the scene, a murder trial jury heard yesterday.

Mr. Hill,18 suffered multiple stab wounds and blunt injuries but it was a single stab wound to the heart that killed him, said the prosecution.

Opening the trial, Deputy Director of Prosecutions, Michael McColm told the jury that the Bermuda Institute graduate was struck repeatedly with crash helmets and a wooden cane.

And he was stabbed with a knife and a screwdriver.

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.

Mr. McColm said: "You may find after hearing all the evidence that one or more defendants had a greater role in the death of Kellon Hill. It will be up to you to decide what role each defendant had in the death.

"The prosecution brings the charge and it is up to the prosecution to prove the charge."

The prosector explained to the jury that the defendants were friends and hung out in the White Hill Field area where Lewis lived.

On the night in question, August 9, a party was held at Elbow Beach for a 14-year-old girl who was having a going-away party organised by her mother.

Invitations were sent out on Facebook and MySpace and about 100 young people attended the party that started around 9.30 p.m.

Mr. McColm said Hairston, Lewis, Simmons and Hollis arrived together and Warner came later with friends and he had a walking cane.

He said the group was annoying people at the party and drinking alcohol out of a large bottle.

"The prosecution says that at one point the defendant Lewis was heard to say 'Somebody was going to get hurt that night'."

He said Lewis was seen with a black knife with a silver blade at the waistband of his pants.

Mr. Hill arrived at the party with three friends around 10 p.m. but decided to leave between 11 and 12 a.m.

Mr. McColm said as he was on his bike and about to ride away, Lewis and Hollis approached Mr. Hill and grabbed his chain.

The jury heard Mr. Hill got off the bike and demanded his chain back but was hit in the face by Hollis. A fight began immediately after.

"Kellon Hill did what he could to defend himself. The prosecution says that the other defendants Warner, Hairston and Simmons were nearby and that they joined in and began to strike Kellon Hill," the prosecutor said.

"While Kellon Hill was being struck, Lewis was seen to remove from his pants an object that looked like a knife and then used it to stab the deceased around his chest and body.

"Simmons was seen with an object that looked like a screwdriver and was seen to stick Kellon with it."

The court heard Mr. Hill stayed on his feet and tried to get away but was struck with the cane by Warner who used so much force that it broke.

Mr. McColm said the youths then ran down towards the beach with Simmons dropping the screwdriver on the way. They hid in the bushes at Coral Beach Club until security guards came and told them to move.

The jury heard the defendants called a taxi and went up to the White Hill Field area.

The male defendants were arrested at 12.39 a.m. at Lewis' home and Simmons was arrested later that day at her grandmother's home.

The trial continues before Puisne Judge Charles-Etta Simmons.
