Forsyth County Sheriff Duane K. Piper called the incident “shocking.”
“It appears that he had a severe break in judgment,” Piper said. “It appears that the entire situation evolved from him being angry at the time it was taking for him to get his food.”
Factors early in the investigation led the agency to believe the suspect was a law enforcement officer, he said.
The man’s actions indicated that he had law enforcement training, Piper said. He also drove his police-issued Impala, which matched the tag number reported by the teens in the vehicle he confronted. The teens attend Lambert High.
A surveillance tape of the incident aided in the investigation, as did witness reports.
“Once we determined it was not going to be one of our officers, we expanded the scope of our investigation and eventually determined it was Mr. Biumi from the DeKalb County Police Department,” Piper said.
Biumi was booked into the Forsyth County Detention Center on Wednesday afternoon. His bond has been set at $22,000, with a court date scheduled for May 23.
Biumi’s employment status with the DeKalb County Police Department is unclear. But what is clear are his disturbing actions captured on video.
“You wouldn’t expect any adult of any type to be acting like this,” Piper said, “but especially, with a law enforcement officer, I think they have even a higher standard of self-control, and to me, that’s the most shocking part.”
