The father of a British football coach, Mike Jones, who has been stabbed to death in New York has told the BBC he learnt of his son's death after being contacted on Facebook by one of his friends.
Perry Jones said:
I contacted the police and I was totally shocked, I was expecting to hear he had been injured in an accident.
We just cannot believe it.
Mr Jones also said his son loved living in New York and was working hoping to get a visa so he could stay there full time.
