A roofer has admitted killing his mother at her Westcountry home last year but denied her murder.
Andrew Cane, aged 30, pleaded guilty to the manslaughter of 63-year-old Linda Sheard but not guilty to the more serious charge of murder when he appeared at Exeter Crown Court.
Mr Simon Laws, QC, prosecuting, said the Crown did not accept the pleas and a date was set for a trial at Exeter on July 15 this year.
Cane, of Port Mer Close, Brixington, Exmouth, denied the murder of his mother between July 9 and 12 last year. He admitted manslaughter.
Mrs Sheard's body was found at the house, where her son was also living, on July 11, 2012. Cane was arrested in Gloucester three days after the alleged murder, after police and his father Michael Cane made a public appeal. His mother's car had earlier been found in Bristol.
Cane worked for the Exmouth-based building contractors DJH Roofers, where his mother also worked as a secretary.
Judge Francis Gilbert, QC, adjourned the case for trial and extended custody limits to allow his continued detention.
