THE sister of murdered Dutch florist Jaap Bornkamp cannot understand why anyone would have wanted to stab such a kind and friendly man.

Gerda Bos and her husband Hilgert travelled from Holland to renew appeals for information, at Scotland Yard, last Friday.

Mr Bornkamp, of Norbury Hill, Norbury, was stabbed in the heart as two men walked past him and a friend, in New Cross Road, at 7.15am on June 4, 2000.

Within seconds the 52-year-old collapsed and was rushed to Lewisham Hospital, but died after three hours in surgery.

Two years later, and with a £20,000 reward, the police investigation continues. Despite interviewing 400 people there have been no strong suspects.

Mrs Bos, who last saw her brother in the March before he died, said: "It has been two difficult years since my brother was stabbed and we miss him very much. It is unbelievable to understand how this could happen.

"It should never happen to anyone else but as long as these men are free they can do it again.

"My beloved brother was a good man who had so many friends. I hope anyone with information can help us."

She joined officers who stopped motorists and pedestrians during an anniversary appeal, in New Cross Road, on Sunday morning.

Investigating officer Detective Inspector Julian Wyard, who offered protection to witnesses, said: "We are very hopeful we will solve this.

"We have been unable to establish a clear motive but we are treating it as a homophobic crime. We hope to make a breakthrough this year. Maybe loyalties have changed and the other man, who did not stab Jaap, could now come forward."

The suspects are white, possibly Mediterranean, both wore baseball caps, one had a cream jacket and red/orange top. The other was thinner and wore dark clothing.

Anyone with information, should call the incident room on 020 8217 6461 or Crimestoppers anonymously on 0800 555 111.
