Police investigating the murder of a teenager have appealed for more information about her movements the day before her body was found.
Rebecca Aylward, 15, was found in woods near Aberkenfig, Bridgend county, at 0900 BST on Sunday 24 October.
Rebecca, from Maesteg, was last seen in Sarn Hill at 1230 BST on Saturday 23 October when she was dropped off by relatives to visit a friend.
A 16-year-old boy has been charged with her murder.
Rebecca was reported missing by her mother when she failed to return home.
South Wales Police said it would like to speak to anyone who may have seen Rebecca in the Church Street area of Bridgend at around 1300 BST on the day she was last seen.
Detectives would particularly like to speak to two men who were seen walking a dog along the street from the direction of Bridgend Road, around 1300 BST and then walking back around 1320 BST.
One of the men was wearing a light or cream-coloured hoodie-type top, said police.
Officers would also like to speak to a man seen being dropped off from a car, possibly a Citroen Saxo or similar vehicle, in Church Street at around 1300 BST, or soon after, who was wearing a red coloured top.
"We would like to stress that these men are in no way suspects but may have information about Rebecca's movements at around this time on the Saturday before her death,' said Det Supt Paul Burke, senior investigating officer for the enquiry.
"If you think you are one of these men, or you were in the area at around 1pm on the Saturday, we would urge you to contact the incident room in Bridgend on 01656 679585.
"You may have some valuable information that could help this investigation.'
