A girl poked Kellon Hill in the side three times with a pointed object on the night he was killed, a teenage boy told Supreme Court on Friday.

Mr. Hill, 18, was stabbed to death as he left a party at Elbow Beach late last August 9.

Five teenagers stand charged with his murder and possessing various weapons charges they all deny.

Prosecutors allege that Kellan Lewis, 17 and Gary Hollis, 16, snatched a gold chain from around Mr. Hill's neck.

A fight ensued, and Kevin Warner, 19, Devon Hairston, 18, and a girl, Zharrin Simmons, 17, are alleged to have joined the other two in striking Mr. Hill.

Next, Lewis is alleged to have removed a knife from his pants and stabbed the victim around his chest and body, before Simmons stuck Mr. Hill with a screwdriver.

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

In evidence to their Supreme Court trial yesterday, Tristan Martin, 17, from Warwick, described a fight he witnessed that night on the road leading to Elbow Beach.

He told the jury: "I saw Gary fighting with Kellon Hill at first, then eventually they all joined in with whatever they had."

Mr. Martin elaborated by stating that he was referring to five people in total.

As he made his way over to what was happening, he saw some helmets swung, which he believed made contact with Mr. Hill three times.

He explained that Hollis, who was fighting with Mr. Hill was "short and brown" and he'd seen him before, although he did not know where. Mr. Hill was a friend he'd known since March last year.

After the helmets, he said, he saw a cane used against Mr. Hill. He could not say who wielded the cane, which swung overarm to hit Mr. Hill twice on the head, as he fought back and tried to hold his own.

Mr. Martin said after the cane, "Kellan jumped in, then the girl jumped in, and by the time I got there it was all over. I was not too far from them."

The witness explained that the girl came up behind Mr. Hill.

"She had something in her hands. Whatever it was, it got him three times on his left side," he told the jury. He described the object in her hands as "like a silver little point or whatever" which was the length of a pen or pencil and held in her right hand.

"She poked him with it three times in his left side," he said, demonstrating this action on his own body. He explained that he did not know the girl or her name.

He could not describe what she was wearing, but told the jury: "She didn't look like a girl, more like a guy wasn't ladylike, you know."

After she "poked" Mr. Hill, the witness said, the girl took off towards the beach. He said of Mr. Hill: "He was just looking at himself, kept touching himself, the blood. Eventually he fell."

Mr. Martin told the court that he went on to push two people off of Mr. Hill, who he believed were Hairston and Lewis.

He knew the latter from Berkeley Institute, where they were in different years. Mr. Martin said he did not see anything in Lewis' hand.

He explained that he left Mr. Hill, who was in pain, and followed Lewis, Hollis, the girl and Hairston down to the beach.

As he did so, he saw the item the girl had in her hand a couple of yards from where he'd seen her with it, lying on the ground by a fence.

He saw the four people on the beach making off at a jogging pace.

He then returned to Mr. Hill, who "wasn't doing too good".

Mr. Martin told the court that the Police and an ambulance came.

Four days later, he attended what he described as "a photo thing" at Prospect Police headquarters, where he was twice shown pictures of people.
