Pamela Wheeler break-in murder: Reward offered
A reward of up to £20,000 is being offered for information which leads to the arrest and prosecution of a 76-year-old woman's killer.
Pamela Wheeler was found dead in her home in Newacres Road, Thamesmead, south-east London, a year ago after an apparent break-in.
Her wrists and ankles were bound.
A post-mortem examination at Greenwich Mortuary found she died of suffocation and a head injury.
The last confirmed sighting of Mrs Wheeler is believed to be on 9 July 2012 when she was shopping in a local Morrisons supermarket.
Det Ch Insp Graeme Gwyn said the investigation remained open into the "horrific and violent death".
Detectives had previously appealed for information regarding two men who had been seen nearby on Newacres Road.
They have since been discounted, said police.
