A witness account that a "woman in red" flagged down drivers for help has added to questions surrounding the death of a Burning Man attendee found bleeding in his tent, authorities and festivalgoers said.

Vadim Kruglov, 37, was discovered in a pool of blood at a campsite in Black Rock City at about 9:15 p.m. on Aug. 30, Pershing County Sheriff's Office investigators said. Detectives have described the incident as a deliberate homicide; law enforcement sources told TMZ that Kruglov sustained multiple stab wounds and his throat had been slashed. Police found a knife and a cellphone near his body, authorities said. The county medical examiner has not released an official manner and cause of death because the investigation remains active.

A witness who said she helped alert authorities told The Hollywood Reporter that the woman, described by the witness as being in her 50s or 60s and wearing a red dress, stopped the couple as they were driving out of the playa. The witness said the woman told them someone in her tent was "bleeding out and might be dead." The couple contacted a Black Rock Ranger they knew, who relayed the information to the Pershing County Sheriff's Office, the witness said. When asked whether the woman had checked Kruglov's pulse, the witness said the woman responded that she "didn't want to touch him."

Other attendees reported discovering Kruglov's bloodied body as the festival reached its climax with the burning of the wooden "Man" effigy. Festivalgoers who spoke with media characterized the campsite area where Kruglov was found as a "free camp" zone where vehicle and RV reservations are not required. Some participants described encounters with an individual they called "unhinged" on the same night, alleging the person claimed to have a knife and said he had to clean blood from his RV; Pershing County Sheriff's Office officials declined to comment on those specific accounts and offered no public description of a suspect.

A Burning Man Project statement released after the death said the organization was cooperating with authorities and extended condolences to Kruglov's family and friends. CEO Marian Goodell said the nonprofit was assisting the sheriff's investigation so "the perpetrator can be caught and brought to justice," and expressed compassion for the wider participant and staff community.

Friends identified Kruglov as a Russian-born artist who lived in Tacoma, Washington, and maintained ties to family in Omsk, Siberia. They said he was not known to use drugs. A GoFundMe organized by friends sought funds to transport Kruglov's body to his hometown and to cover funeral expenses.

Pershing County detectives said they are following "several leads" provided by the public. Officials have not released additional details about the manner of death, suspect descriptions, or whether anyone has been arrested.

Burning Man draws tens of thousands of participants annually to the temporary community on Nevada's Black Rock Desert and is known for its countercultural ethos. The festival's organizers and volunteers have previously worked with local and federal law enforcement on isolated incidents during the event, and the Pershing County Sheriff's Office has said it will continue investigating the circumstances surrounding Kruglov's death.

Authorities asked anyone with information about the case to contact the Pershing County Sheriff's Office. The investigation remains active and ongoing.
