The sheriff says recovered evidence is being analyzed nearly two months after a man went missing under “concerning circumstances” near Mundelein, prompting a heavy police and fire department search.

The Lake County Sheriff’s Office announced on November 12 that they were searching for Ruslan Furman, 51, who was last known to reside in the 26500 block of North Route 60-83 in unincorporated Mundelein.

Lake County Sheriff’s Office Deputy Chief Christopher Covelli said Furman had not been seen in over a week from November 12, meaning he went missing prior to November 5.

Detectives said they believed there was foul play linked to his disappearance.

Covelli said Furman was missing under “concerning circumstances” but has declined to elaborate further.

Furman was last seen near his home and was last seen wearing blue jeans and a t-shirt.

He is 6-foot-2 and 220 pounds with brown hair and brown eyes.

Prosecutors had mentioned in court last month that the case was possibly a homicide.

Covelli told Lake and McHenry County Scanner in an update on Monday that detectives are still treating it as a missing person investigation.

The Lake County Sheriff’s Office Criminal Investigations Division continues to actively investigate the disappearance.

Numerous pieces of evidence collected pursuant to search warrants have been sent to the crime lab for forensic analysis, Covelli said in the update.

“Our belief that foul play is a factor remains consistent at this point,” he added.

Members of the sheriff’s office, the Illinois Department of Natural Resources and the fire department searched Diamond Lake throughout the day on November 14 for any evidence of his disappearance in the lake.

The Mutual Aid Box Alarm System (MABAS) was activated to bring boats, divers and sonar equipment from throughout the area to the scene.

Canine units were also searching by land around Diamond Lake on the morning of November 14.

Furman remains missing despite the searches, Covelli said, adding that crews continued searches on November 15.

A portion of Route 83 between Diamond Lake Road and Midlothian Road was shut down.

Detectives remained in the area from around 1 p.m. until the evening hours.

Investigators arrested Dmitry Bogatiryov, 52, of Mundelein, and Damen Voranoff, 55, of Mundelein.

Covelli said the two men were found in possession of firearms and a large amount of cannabis inside their residence during a search warrant in connection with the missing person investigation.

Voranoff was charged with unlawful possession of a firearm without a FOID, manufacturing or delivery of 500-2,000 grams of cannabis and possession of cannabis between 2,000-5,000 grams.

Voranoff does not have a valid Firearm Owner’s Identification card or concealed carry license. He does not have an extensive criminal history, Theis said, adding that he was on pre-trial release for a misdemeanor child endangerment case.

Lake County Assistant State’s Attorney Dino Katris said Bogatiryov was found with four guns, 1,437 grams of flower cannabis, 1,227 grams of cannabis oil and 75 grams of cannabis wax.

Bogatiryov also does not have a valid Firearm Owner’s Identification card.

The charges against both of the men are non-detainable. Bogatiryov was released on pre-trial release conditions but Voranoff was ordered held in the Lake County Jail following a hearing to revoke his pre-trial release in his prior case for committing the new offense.

Bogatiryov and Damen are scheduled to appear in court again on January 6 for an arraignment hearing.
