Stab wounds to the heart and the lung caused the death of young mother Chena Trott, a Supreme Court jury heard yesterday.

Although legal arguments dominated yesterday morning?s trial session, the court heard medical evidence from pathologist Dr. Valerie Rao who performed a post-mortem examination on Ms Trott?s body.

Dr. Rao said Ms Trott sustained six stab wounds to her chest, upper abdomen and back. The five man, seven woman jury heard that the young mother of three died after the fatal stab wound punctured her heart and impaired her breathing while causing severe blood loss.

The second wound went into Ms Trott?s back through one of her upper ribs and into her right lung.

?It required an extensive degree of force to go through the cartilage in that area,? said Dr. Rao, explaining the wounds indicated a knife had been used to inflict the injuries.

George (Messy) MacDonald Liburd is charged with murdering Ms Trott in August, 2002 at the Crawl Esso Tigermart in Hamilton Parish.

Liburd has pleaded not guilty to murder but guilty to manslaughter with diminished responsibility.

The plea, that is not accepted by prosecution lawyers, means lawyers for the defence must show that Liburd was suffering from an abnormality of the mind which impaired judgment at the time of the killing.

Injuries found on Ms Trott?s body included abrasions on her lip caused by blunt trauma such as a punch, a cut on the lip, and bruising on her forehead and on the inner thigh. She also sustained a stab wound in her left breast and bleeding under her skin in the front chest area. One of the wounds found on the right side of her chest measured two and a half inches in length.

The pathologist told the court how Ms Trott, a healthy 33-year-old with no medical conditions, fought for her life during the ride to hospital. At the hospital an IV line was inserted into her body as doctors attempted to save her life. ?She survived long enough to get to the hospital but she did not live long,? Dr. Rao told the court.

Earlier this week the court heard eyewitness testimony from David Myron Brangman, the man who tried to stop Liburd from driving a knife into Ms Trott during the attack. He told the court that Liburd wielded a knife covered with white material that he kept thrusting repeatedly into his victim while fending off anyone who attempted to stop the daylight attack.

Dr. Rao was shown photographs of a knife found at a Dudley Hill, Paget residence, and she agreed that the weapon could have caused Ms Trott?s injuries since the edges were consistent with the size and depth of wounds found on Ms Trott?s body. The court also heard evidence from bailiff Franklin Roberts who confirmed that Liburd and Ms Trott began a relationship in July, 1999. On August 6, 2002, three days before her death, Ms Trott applied for a temporary domestic violence protection order, meaning Liburd was to have no contact with her or her children for 28 days. The bailiff also served a notice of a hearing for a grant of a permanent protection order which would exceed the 28 days and protect Ms Trott from Liburd for at least 12 months.

The order prevented Liburd from inflicting psychological abuse against the complainant or her children, from entering her Smith?s home, and from going to her workplace or her children?s school.

The order also extended to phone calls, meaning Liburd could not call Ms Trott at the Devon Springs Recycling Plant where she worked, on her mobile, or at her home.

Mr. Roberts served the order to Liburd at his Fenton Drive residence in Pembroke the following day.

?I spoke to him, I told him who I was, I read the document to him,? he said.

?He seemed OK.?

Liburd, whose case has been repeatedly adjourned over the last three years, told Police after the killing: ?I used a knife to kill her, that girl is a f***ing bitch, I?d do it again. When I loved we loved deep. That girl played a f***ing game on me, I?d f***ing do it again?.

The trial continues today before Puisne Judge Charles Etta Simmons. Liburd is represented by Queen?s Counsel John Perry.
