Sam Mechelewski, 20, was captured on CCTV at a branch of Sainsburys in St Germain Walk, Huntingdon, shortly before 8pm on January 31. His body was found by a member of the public at about 1pm the following day ( February 1) in a wooded area of Hinchingbrooke Country Park. Officers are keen to speak to anyone who saw Sam after the sighting of him in Sainsburys. House-to-house enquires have taken place close to where Sams body was discovered and extensive searches have taken place in the park. Detective Chief Inspector Adam Gallop said: A week after the discovery of Sams body we are again appealing to anyone with information to contact us as a matter of urgency. If you recognise Sam from the CCTV image and saw him on the evening of 31 January please get in touch. You may feel that information you have is insignificant, but it might help us piece together Sams movements in the final hours of his life. I would like to emphasise again that I believe this was a targeted attack, but one that sadly resulted in the death of a young man. In a statement, Sams family said: The killing of our son at 20 years of age, when he had his whole life ahead of him is devastating. Please if you have any information no matter how insignificant you think it may be please contact the police.
