In January 2017, a visit to family and friends in Holly Springs, Georgia, turned tragic for 43-year-old Bryan Overseth, a male resident of Bigfork, Montana. On the night of January 21st, Overseth was discovered deceased on a private access road within the Harmony on the Lakes subdivision. An investigation was immediately launched by the Holly Springs Police Department, along with the Georgia Bureau of Investigation and the Cherokee County District Attorney's Office.
The cause of death was determined to be a single gunshot wound to the head.
The investigation quickly led authorities to a suspect, 34-year-old Robert Derek Gialenios of Gainesville, Georgia. It was revealed that Gialenios had been involved in a long-distance affair with Overseth's wife, Kerri. The relationship had reportedly ended, but Gialenios continued to pursue her. Evidence presented during the investigation showed that Gialenios had stalked Kerri Overseth, even contacting her through social media and leaving items at her sister's home. Initially, Gialenios was arrested on charges of loitering, prowling, and stalking. However, these charges were soon upgraded to include malice murder.
In April 2017, a Cherokee County grand jury indicted Robert Gialenios on multiple charges, including malice murder, felony murder, aggravated assault, possession of a firearm during the commission of a crime, stalking, and loitering and prowling. The indictment specified that Overseth had been killed with a. 22 caliber firearm. A firearms examiner later testified that the bullet recovered was consistent with being fired from a Walther P22 pistol, a model of gun that Gialenios was known to own.
Following a jury trial in 2019, Robert Derek Gialenios was convicted of malice murder and possession of a firearm during the commission of a felony. He was subsequently sentenced to life in prison without the possibility of parole, with an additional five years for the weapons conviction. An appeal of his conviction was later denied.
