Police issued a new appeal today for information about the final movements of murdered schoolgirl Rebecca Aylward.
The body of the 15-year-old was found in a wooded area near Aberkenfig, Bridgend, south Wales, on October 24.
A 16-year-old boy was later arrested and charged with her murder.
South Wales Police (SWP) are trying to piece together the teenager's movements on the day before her body was discovered.
"The last confirmed sighting of Rebecca was in Sarn Hill, Sarn, at around 12.30pm on Saturday October 23 when she was dropped off by relatives to visit a friend," an SWP spokeswoman said.
"She was reported missing by her mother in the evening when she failed to return home.
"Police would now like to speak to anyone who may have seen Rebecca in the Church Street area of Bridgend at around 1pm on Saturday October 23."
She added: "They would particularly like to speak to two men who were seen walking a dog along the street from the direction of Bridgend Road, around 1pm and then walking back around 1.20pm.
"One of the men was wearing a light or cream-coloured hoody-type top.
"They 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 1pm, or soon after, who was wearing a red coloured top."
Detective Superintendent Paul Burke, senior investigating officer for the inquiry, said: "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.
"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."
