Case is shrouded in fevered speculation as prosecutors say autopsies show two of the deceased were “probably” murdered

It has been dubbed Bulgaria’s “Twin Peaks”: a grim saga involving the mysterious deaths of six people in the middle of the mountains that has gripped the eastern European country.

Zahari Vaskov, the director of the national police general directorate, told a press conference on Monday that the deaths were “a case without comparison in our country”.

Fittingly, perhaps, for an investigation that has been shrouded in sensationalised conspiracy, conflicting accounts and fevered speculation, Borislav Sarafov, the general prosecutor, gave his own verdict. “Life has given us more shocking details here than in the Twin Peaks series,” he told local media, alluding to the 1990s US television drama.

The case began at the start of February, when three men aged 45, 49, and 51 were found dead in a the burned-out remains of a lodge near the Petrohan pass, a mountain pass that connects Sofia province with the northwestern Montana province.
