The boyfriend of Catherine Wells-Burr has appeared in court accused of conspiracy to murder her.
Rafal Piotr Nowak, 31, faced magistrates in Bristol a day after his former partner, Anna Julia Lagwinowicz, 32, was at the same court to face the same charge.
Nowak is charged with conspiring with Lagwinowicz and others to murder his girlfriend, which is said to have been committed between May 1 and September 13.
Through an interpreter, the Polish national, who wore dark blue jeans and a blue and white checked shirt, spoke only to confirm his name, age and address.
Jeffrey Bannister, defending, did not make an application for bail, telling the court: "As a tragic consequence of this incident, my client is not able to go back to the address he shared with this young lady. As a result, he cannot put forward an address."
Nowak, of Willow Way, Chard, Somerset, was remanded into custody to appear alongside Lagwinowicz at Bristol Crown Court on October 9.
A 38-year-old man arrested in connection with the inquiry remains in police custody.
Miss Wells-Burr's body was found inside her burning Ford Focus car off the A358 near Ilminster, Somerset, on Wednesday last week by firefighters alerted to the blazing five-door vehicle by passing motorists.
Miss Wells-Burr, 23, who was known as Caf, gained a first-class degree in business management at Bath Spa University and went to work as a business analyst for Chard-based Numatic International Ltd, known for the Henry vacuum cleaners.
Her parents Jayne and Phil Wells-Burr, who have office jobs at the firm where her boyfriend also works, said their daughter was an "amazing, special person" who was excited about starting a new life with him.
