The family of an 89-year-old woman who died after an attack in her home have appealed for information to help track down her killer.
Police do not have a motive for the attack
Olga Turner was left with serious head injuries in the assault in Great Barr, Birmingham, on 3 October.
She died in Good Hope Hospital, Sutton Coldfield, 11 days later and police started a murder inquiry.
West Midlands officers say nothing was stolen from Mrs Turner's home and they do not have a motive for the attack.
The offender got into Mrs Turner's house through the front door, which had been left open because she was expecting a visit from her family.
John Price said he could not understand why anyone would want to harm his mother-in-law.
"She was everybody's idea of the typical little grey-haired old granny," he said.
"She was a very frail lady, but a very proud and independent lady - just a lovely granny."
Det Ch Insp Chris Pretty said: "This was a totally unwarranted attack on a frail old lady in her own home.
"The degree of violence used was completely over the top. She had not got an enemy in the world."
Police are appealing for anyone with information about the attack to come forward.
