CCTV released in Ian Hamilton road death mystery
Police investigating how a man was found found dead beside a road in the south Wales valleys have released CCTV footage.
The body of Ian Hamilton, 27, was discovered near Pontllanfraith in Caerphilly county early on Sunday.
Officers are urging anyone who was walking or driving along Penmaen Road between on 02:00 and 04:00 BST on 17 July to come forward.
They want to trace the owners of these three vehicles on the CCTV.
The cars were seen on the road near where Mr Hamilton was found at the time.
Mr Hamilton, who was from Bristol and was also known as Parker Hamilton, was visiting family in the area and is known to have been at a social event the previous evening.
He was seen walking from the bus station in Blackwood and it is known he walked along Penmaen Road towards Oakdale.
On Wednesday, his family paid tribute to Mr Hamilton saying he "was kind and generous and enjoyed keeping fit and was well known for his running."
Officers have conducted house-to-house inquiries and are continuing to investigate the death which is still being treated as unexplained.
Anyone with information is asked to contact Gwent Police on 101.
