The boyfriend of a university graduate whose body was found in a burning car has denied her murder.
Rafal Piotr Nowak, 31, appeared at Bristol Crown Court jointly charged with the crime with his former partner Anna Julia Lagwinowicz, 32, and Tadevsz Dyytryszyn, 38.
It is alleged they killed Catherine Wells-Burr, from Chard, Somerset, between September 10 and 13 last year.
The 23-year-old business analyst was discovered by firefighters in a burning Ford Focus beside the A358 at Ashill, near Ilminster, Somerset.
Polish nationals Nowak, of Willow Way, Chard, Lagwinowicz, of South Street, Taunton, and Dmytryszyn, of Holway Avenue, Taunton, sat alongside each other with an interpreter for the hour-long hearing.
They each spoke to confirm their names and enter not guilty pleas to the single count of murder.
Miss Wells-Burr's family attended court to hear them deny the charge.
The judge, Mr Justice Lindblom, adjourned the case for trial on April 10, with a further hearing on March 18.
Richard Smith QC, prosecuting, told the court the trial is expected to last between six and eight weeks.
There was no application for bail on behalf of the defendants.
Miss Wells-Burr, who was known as Caf, gained a first-class degree in business management at Bath Spa University.
She then went to work for Chard-based Numatic International, known for the Henry vacuum cleaners.
Her parents, Jayne and Phil, have office jobs at the firm where Nowak used to work.
