UPDATE: Man gets life in prison in murder of mistress’ husband in Cherokee County

A Gainesville man will spend the rest of his life in prison after he was convicted of murder in the 2017 death of his mistress’ husband.

Bryan Overseth, 43, of Big Fork, Montana, was shot in the head and killed Jan. 21, 2017, in the Harmony on the Lakes subdivision of Holly Springs. He, his wife and their children were visiting friends and family when Overseth was shot outside a relative’s home.

Overseth’s wife told Holly Springs police at the time of his death she believed Robert Gialenios, 36, was responsible. She and Gialenios were having an affair but had called things off, court records show. She told investigators he wanted her to leave her husband. 

Gialenios was arrested one week after Overseth’s murder, after he was spotted in the backyard of a Canton home where the woman was temporarily staying with family. He left her a single rose and a greeting card on a back patio.

A jury on Thursday found Gialenios guilty of malice murder, felony murder, aggravated assault and possession of a firearm during the commission of a crime. He was also indicted on charges of loitering and stalking, but those charges were dropped as a result of the murder conviction, court records show. 

On Monday, Gialenios was sentenced to life in prison, plus five years on the weapons conviction. A judge denied him the possibility of parole.
