For the second time in four years, federal authorities searched the property of a Franklin County man, who became famous on YouTube for his videos showing him blowing up cars, refrigerators and shooting various firearms.

The search for firearms and explosives on Aug. 8 fell on the heels of the Franklin County Sheriff’s Office arresting Kyle Lamar Myers, 30, that same day on charges of illegally obtaining drugs shipped the previous day to his post office box in Carnesville.

Myers received a package in the mail that contained drugs and after his arrest, U.S. Alcohol, Tobacco, Firearms and Explosives agents obtained a search warrant to search Myers’ property for guns and explosives, according to ATF spokesman Nero Priester.

More than 50 firearms were seized, but no illegal explosives were found, Priester said.

Myers’ YouTube station, FPS Russia, gained notoriety in January 2013 when his business partner in FPS Industries Global LLC was found slain inside the business outside Carnesville. The slaying of 32-year-old Keith Ratliff remains unsolved.

The Georgia Bureau of Investigation conducted the crime scene investigation.

"There were no signs of forced entry at the business and the surveillance equipment, along with some firearms, had been taken. There did not appear to be a struggle of any kind, and based on the scene, Ratliff died while he was working," the GBI said in 2015, nearly two years after the case went cold.

Ratliff, who was also manager of the YouTube channel, may have been killed by a person or persons he trusted, the GBI said.

Authorities said the video channel had "millions of followers."

In one of Myers’ videos posted in April 2015, he told his audience he had "no idea" who killed Ratliff.

"Who is to say? I loved Keith," Myers said, adding that Ratliff had a "rocky personal life with women."

When making videos where he shot guns and blew up objects, Myers tried to imitate a Russian accent as he described the action.

In March 2013, the ATF, accompanied by local and state officers, searched the home of Myers on the basis he might have explosives that violated federal law. At the same time, the ATF said officers searched the 60-acre farm of Myers’ father, Lamar Myers. The search did not lead to any charges.

In the recent search at Myers’ home, federal authorities seized guns "in conjunction with a federal statue that prohibits any illegal drug user from having firearms," Priester said.

"We’re waiting for lab results to come back. We got a subpoena for his blood to see if he is an active drug user," he said, adding that if tests show he was using illegal drugs the ATF will consider presenting a case to the U.S. Attorney’s Office.

Myers, who faces state charges of possessing a schedule one drug and possession of drug-related objects, is free on a $10,000 bond. The type of drug alleged in the warrant was not immediately available.

The GBI said it believes the person or persons who killed Ratliff are known to other people and these people could pose a threat to the killer, which puts them "at a continued risk of harm."

Anyone with information on Ratliff’s death is asked to call the GBI at (706) 552-2309 or the sheriff’s office at (706) 384-2525.
