Brenton James Garmon, a one-time captain with the Bartow County Sheriff’s Office, has been sentenced to 13 months in federal prison following his guilty plea to charges of embezzling more than $80,000.  While in charge of the narcotics unit at the sheriff’s office, Garmon was supposed to be putting money seized during drug busts into a safety deposit box.Instead, he pocketed $80,493 for himself between 2004 and 2007, according to the U.S. Attorney’s Office.Garmon had apparently been having money problems. He used some of the money to avoid foreclosure on his home after his monthly payments ballooned because of an adjustable-rate mortgage, prosecutors said.He pleaded guilty to embezzlement in February.
