ROSEBURG, Ore. (AP) — The boyfriend of a Georgia teen charged with killing her mother and brother in a house fire was also arrested in connection with their deaths.

The 17-year-old boyfriend was arrested Thursday afternoon after investigators in Georgia and Oregon found evidence connecting him to the deaths, the Monroe County Sheriff’s Office said in a Facebook post. The 17-year-old, who lives in Oregon, will have extradition hearings to face murder charges in Georgia, the sheriff’s office said.

Investigators said his girlfriend, Candance Walton, set fire to the home near Forsyth on Feb. 27. She was extradited from Kentucky in March on arson and murder charges after her brother, Gerald Walton, and mother, Tasha Vandiver, were found dead after the fire.

Candance Walton, 16, told officers she was on her way to Oregon after they pulled her over in Paducah, Kentucky, that same day while driving her mother’s 2007 Chevrolet Malibu.

Monroe County Sheriff Brad Freeman told The Telegraph of Macon in March that deputies believed Walton was on her way to Oregon to see her boyfriend. The sheriff said authorities also found “incriminating things” after searching her car.

Juveniles age 13 and older in Georgia are automatically charged as adults when they are charged with murder and some other crimes.

Deputies did not provide information on the evidence they used to charge the 17-year-old in the case.

It was not immediately clear if either suspects had lawyers who could comment on their behalf.
