A MAN who made the grim discovery of man who had been stabbed to death said he had spent that day with the alleged murderer.

Edward Kantanka told Ipswich Crown Court he was on the telephone when he heard his two friends Francis Koomsan and Kwabena Asumadu arguing upstairs.

He said the row went on for half an hour before there was a scream and then silence.

Asumadu came downstairs and left the St Johns Place terraced house in Bury St Edmunds with a bloody lip.

Mr Kantanka went upstairs and found Mr Koomsan also known as Prince Kofi Koomsan dead on the bedroom floor. The 22-year-old had been stabbed 13 times with a sharp kitchen knife.

Mr Kantanka said: “I tried to check for life signs but I was scared. I had never experienced such a thing. I'm not an expert but I thought he was dead by then.”

Asumadu has denied murder on December 24 last year.

Mr Kantanka told the court that Mr Koomsan shared the house with Asumadu and Daniel Frimpong and the three also worked together as car valeters at EMG Garage in Bury St Edmunds.

He said that he had spent the day before Christmas Eve with 28-year-old Asumadu and they had gone to various pubs in Mildenhall, watched football on television and played pool before returning to St Johns Place that evening.

Mr Kantanka said: “I had three pints of beer and Kwabena didn't drink so he was drinking Red Bull.”

However police said three hours after the murder Asumadu tested positive for alcohol and would have been drunk at the time of the attack.

Mr Kantanka said the row began when they arrived home and Mr Koomsan complained about the loud music being played by Asamadu.

He said Asumadu did not turn the music down but followed Mr Koomsan upstairs and continued arguing. Mr Kantanka said the row ended after he heard a scream.

The trial which is expected to last five more days continues.
