An e-fit of a man wanted for questioning in connection with the murder of 90-year-old widow Elsie Hughes has been released by police.
The man they want to question wore a hooded top
Detectives want to trace a man who was seen near her home in Abermorddu, near Wrexham, on the night she was attacked.
An appeal has been made for a couple seen talking to a man fitting his description outside a take away in the town to contact police.
Mrs Hughes was battered to death in her home on Thursday.
The murder investigation team want to speak to a man, wearing a light hooded top, seen walking towards Mrs Hughes home.
5' 10", medium build
25-30 years old
Short, dark hair, with a fringe
Light coloured hooded top
Dark tracksuit bottoms
No distinctive accent
He is believed to have been in a takeaway restaurant nearby earlier on in the evening and is thought to have spoken to a couple outside the Kowloon House in Hawarden Road.
The police renewed their appeal for the couple seen in a people carrier parked outside the takeaway on Hawarden Road to speak to officers immediately.
Officers think they could hold information which could assist in the search for the man they want to question.
"We are repeating our appeal for this couple to come forward as it is possible they may have significant information which could further assist in the inquiry," said Detective Chief Superintendent Ross Duffield who is leading the inquiry.
Mrs Hughes was attacked in her home
"We have sightings of the people carrier parked on the same side of the road as the take away and it is later seen to drive off in the direction of Hope.
"If you are the man and the woman described, please come forward and speak to us in the incident room."
Police also want the driver of a dark coloured Ford Escort van seen on Hawarden Road between 1700BST and 1900BST on the night Mrs Hughes was attacked to come forward.
It was seen parked on the opposite side of the road to the Kowloon House and police think it is possible the same vehicle was seen to emerge from nearby Crossways soon after the last known sighting of the hooded male as he was turning into the area.
On Monday, Mrs Hughes granddaughter, Claire Hughes, described her murder as a "senseless and wicked act" which had "devastated our small, close family".
Mrs Hughes, who had been a head cook at a local school, died in hospital on Friday. Police - who described her murder as "savage" - have not established a motive for the murder.
Mrs Hughes had been the victim of a distraction burglary at her home in August during which her savings were stolen.
