The mother of Joanna Yeates has offered to take part in a TV reconstruction of her daughter's last-known movements.
Avon and Somerset Police are planning a reconstruction of the landscape architect's last steps, which will be shown on the BBC programme Crimewatch later this month.
Theresa Yeates, 58, is keen to take on the role because she is of similar height and build to her daughter.
Her husband, David, 63, told The Sunday Times: "My wife looks a bit similar to Jo and would like to take the part. I don't know whether the police will involve us at all."
Her request came as details of the supposedly final text message Miss Yeates sent on the night she disappeared in Bristol emerged.
Friend Matthew Wood told The Sun he received a text from her at 8.20pm on December 17, saying: "Where are you? Do you fancy a drink?" He said he replied back at 9.20pm that night, but never received a reply.
Miss Yeates was last seen buying pizza at a Tesco supermarket 8.40pm.
Detectives said Miss Yeates had made it home because her shoes, coat, mobile phone, purse and keys were found there - although the pizza, the wrapping and its box are still missing.
When Mr Reardon - who had been away for the weekend visiting family in Sheffield - returned to Bristol two days later, he raised the alarm.
Police launched a massive hunt for Miss Yeates and her snow-covered body was found by a couple walking their dogs on Christmas morning in a country lane in Failand, North Somerset - just three miles from her home. She had been strangled.
