Police have named the man who was found with multiple stab wounds outside a house in Worcester yesterday.
Adrian Locke, 39, was discovered by paramedics on Teme Road in the Tolladine area at 7.22pm after a call from members of the public.
Mr Locke, who was of no fixed abode, was confirmed dead at the scene shortly afterwards.
Police say Mr Locke, whose family are believed to be from Worcestershire, was staying with a friend when he was found outside a neighbouring property.
Leading the investigation Chief Inspector Paul Kinsella said:
"The investigation team are at a very early stage in their inquiries and need to speak to anyone who knew Adrian and who saw him yesterday.
"They are particularly interested in his whereabouts between 5pm and 7.20pm.
"We need to trace anyone who was at the scene, particularly before the emergency services arrived.
"We are especially keen to hear from anyone who saw someone or some people make off from the scene, whether that was on foot, by bike or in a vehicle."
