Yuravak occasionally worked at the garage, but Billy Scimenes, who owns the business, said he didn't know the two women.
"It was horrible," Scimenes said. "Imagine going to work and expect to see people working and instead finding three dead bodies."
Investigators said drugs may have been involved, though Scimenes said he was not aware of Yuravak having a drug problem.
"We do not tolerate drugs or drug use at our business," said Scimenes. "I never saw any drugs on the premises. I don't know what people do at night when they are away from work."
The victims were all shot in the head. Court records show that Hockenberry lived in Euclid, Sarli lived in Eastlake and Yuravak lived in Grafton.
Cleveland City Councilman Michael Polensek, whose ward includes the garage, said he was stunned, as he believes the neighborhood is quite safe. He said he was shocked that each victim had been shot in the head.
"This is horrific," Polensek said. "When you shoot three people in the head, that's execution. This was no robbery. (The victims) knew their shooter."
Polensek said Scimenes left his shop about 7:30 p.m. Thursday, and the victim was still working there. When Scimenes approached the shop Friday morning and heard the radio playing and saw the lights on, he believed the man had come in to start working early, the councilman said.
Scimenes often works on older cars, fixes them and sells them, Polensek said.
