The 21-year-old man suspected of killing his parents and three other people—including a girl he was dating—was arrested Sunday when he drove up with a gun to his grandmother's house in Virginia, a sheriff said. On Saturday, Dakota Theriot shot and killed three people—the woman believed to be his girlfriend, her brother and father—in Louisiana's Livingston Parish before taking her father's truck, driving to neighboring Ascension Parish, and shooting his parents, according to authorities. Theriot's grandmother in Warsaw, Virginia, had checked into a hotel Saturday night, fearing he might show up there, Richmond County Sheriff Stephan B. Smith said in a phone interview with the AP.
The woman asked authorities to check her house Sunday morning to make sure it was safe before she returned. While deputies were there, Smith said, Theriot drove up with a firearm pointed out the window of a pickup truck. A sheriff's statement said deputies sought cover and challenged Theriot, who then dropped the gun and was arrested without incident. He said the pickup Theriot drove to his grandmother's house apparently was the one taken in Louisiana. Theriot will be brought back to Ascension Parish to be booked on two counts of first-degree murder, home invasion, and illegal use of weapons, said a statement by Ascension Parish Sheriff Bobby Webre and Livingston Parish Sheriff Jason Ard.
