The manhunt for a 35-year-old wanted in connection with "two brutal murders", including one in Middlesbrough, is continuing.
More than 100 officers are involved in the search for James Allen following the deaths of Colin Dunford in Middlesbrough on Monday and Julie Davison in Whitby, North Yorkshire, on Wednesday.
Allen is known to police and members of the public are urged not to approach him but dial 999.
Cleveland Police and North Yorkshire Police issued a joint appeal to find Allen after officers linked the two deaths, with detectives describing the killings as "two brutal murders in the victims' own homes".
A post-mortem examination on Mr Dunford, 81, showed he had also suffered serious head injuries as a result of a significant assault.
He was found dead at his terraced house in Leven Street, Middlesbrough, on Monday after he failed to appear at his favourite club.
Locals said the dead man was a daily visitor to the Samuelsons Working Mans Club directly opposite his home and it is believed that when Mr Dunford was not seen at the club where he often ate his evening meal, members became worried and the police were called.
Detectives said there was no sign of forced entry at the house.
Mr Dunford was last seen alive at around 5pm on Sunday.
Allen is described as 5ft 7in, with a bald head and tattoos on both arms.
