The body of Koray Alpergin, the owner of London station Bizim FM, was discovered in Loughton, Essex, on October 15.
Ali Kavak, 25, appeared at the Old Bailey today via video link along with Steffan Gordon, 33.
Prosecutor Peter Ratcliffe said the case involves the “imprisonment, brutal torture and execution of Koray Alpergin”.
The court was told Koray and Ms Dalbudak were returning home to Enfield, North London, on October 13 when the horror unfolded.
Nicholas Hearn, prosecuting, said previously: “They were attacked by individuals wearing white masks and bundled into a van and taken to a location and held there against their will.
“Mr Alpergin was badly beaten and murdered. On Saturday 15 October, two days later, Mr Alpergin’s body was found by members of the public in a woodland area in Loughton, Essex.
“The body was naked and had sustained burns, bruises and cuts.”
A post mortem gave a preliminary cause of death as strangulation, blunt forced trauma and damage to the internal organs and ribs, it was said.
Ms Dalbudak, who was visiting from Istanbul, was later located and was physically unharmed.
A GoFundMe page, launched by his family and friends, reads: “Koray was loved by everyone who had the pleasure of knowing him.
“A much-loved member of his family, a special friend to all and a huge member of the community with the biggest heart.
“Koray always thought of everyone, he was kind and caring and always supported those around him. He was such a light in the community, loved by his family, treasured by his friends and he lived his life to the fullest.”
Kavak was remanded in custody ahead of a provisional trial date on September 18.
Gordon and a third defendant Junior Kettle, 31, are yet to enter pleas to murder.
Erdogan Ulcay, 55, and a 17-year-old boy are charged with perverting the course of justice by assisting with the disposal of Koray’s body.
They will next appear at court on March 8.
