A COLLEAGUE of murdered company director Kingsley Monk told a jury how he was tied around his wrists and feet and placed inside the toilet of offices in New Inn.

Gethin Heal told Newport Crown Court today how he could hear Mr Monk's screams coming from the main office.

"The screams were haunting" he said, “it was terrible.

"I have never heard anything like it before.’’ Russell Carter was described as being expressionless during the incident last October.

The truck driver accused of killing his boss during a four-hour ordeal had a "cold and blank’’ look on his face, the court was told.

The 52-year-old from Rumney, Cardiff, denies murdering Kingsley Monk and the attempted murder of three other Driverline 247 employees.

A jury heard during the opening on Monday how Carter thought he was owed money by father-of-two Mr Monk and resented being called a "coward’’ on a phone message after he failed to turn up for work.

Carter used cable ties and rope to bind Mr Monk and colleagues Gethin Heal, Nathan Taylor and Robert Lewis, the court heard.

When asked by prosecutor David Aubrey QC about Carter's demeanour throughout the incident, Mr Heal replied: "He was blank and cold. There was never any expression on his face; it was just blank.’’
