The defendant in a murder trial told jurors “I’m not a killer” as he gave evidence yesterday.

Robert Chin, 43, took the witness stand at Oxford Crown Court, where he denies fatally stabbing Devon McPherson — also known as Wycombe Jay — in East Oxford on May 18.

Chin, who spoke with the aid of a Jamaican Patois interpreter, said he came to England in November 2008 under the name Headley Thompson.

Asked whether he had ever boasted of being on Death Row or telling Mr McPherson he killed for fun, Chin responded: “I’m a godly person. The Bible says thou shalt not kill. I didn’t tell him I kill for fun. I’m not a killer.”

The father-of-ten said he took Viagra but not illegal drugs, before he admitted drinking cannabis-laced iced tea to aid his bronchial asthma.

The jury heard Chin has convictions including robbery and unlawful wounding in Jamaica during the 1980s, and for possessing cannabis in the United States.

After being deported from America, he came to London using the passport of a friend’s dead boyfriend and met Derek Johnson, nicknamed ‘Little Man’, whom he had known in Jamaica.

Chin said he was brought to Oxford by Little Man and lived in Ridgefield Road and Cumberland Road between November and May.

Chin, who cannot read or write, said Little Man sold drugs from his room and paid the rents.

He denied ever dealing drugs and said he got money by charging prostitutes to use his bed and by doing sporadic painting and cooking work.

On the day of the stabbing, Chin said he had cycled to Magdalen Road to buy oranges and was returning home when Mr McPherson pulled him to the floor and took his jacket and the bicycle.

Chin said: “Wycombe Jay said it’s not you I want, I want Little Man.”

On returning to his room, where Little Man was sitting on his bed, Chin said he peeled the oranges with a kitchen knife and told him about the incident.

He said: “Little Man took the knife and went outside. He never said nothing at all to me.”

Chin said he then watched a DVD of his daughter’s birthday party and fell asleep. Later, Little Man came back and the pair were driven to London with two other men.

Chin told the jury he heard no mention of a stabbing. He said he was told to get out in West London and Little Man warned him to stay away from Oxford, but he did not ask why.

The jury has heard that ‘Little Man’ is wanted by police for drugs and immigration offences.

Under cross examination Chin denied stabbing Mr McPherson, and added he was “not the sort of person” to get angry or hold a grudge.

The trial continues.
