Suspect of five Louisiana killings arrested in Virginia


Dakota Theriot, the suspect of five murders in Louisiana, was caught in Virgina on Sunday at his grandmother’s house. Theriot will be transferred to Ascension Parish in Louisiana and charged with mutliple counts of first degree murder, home invasion, and illegal use of weapons.

Theriot’s grandmother had fled her house to a hotel on Saturday night when she heard about the killings in Louisiana because she feared he would come for her next.

She asked police Sunday morning to check her house before she returned. While they were on scene, Theriot arrived with a firearm pointed at the window. Police took cover and ordered Theriot on the ground and took him into custody wihtout incident. 

Theriot is believed to have killed Billy Ernest, 43, his son Tanner, 17, and daughter Summer, 20, in their Livingston Parish home early Saturday before driving to his parents home and shooting them as well.

Theriot’s father, Keith, made a dying declaration to police that his son had been the shooter. 

“The father was gravely injured at the time we found him and has since passed away,” Parish Sheriff Bobby Webre said. “We were able to get a dying declaration from him, only enough information to let us know it was his son that committed this act.”

Dakota Theriot had recently lived with his parents, but was quickly kicked out and told not to return.

He recently had started a relationship with Summer Ernest. Her mother told Webre that she “saw no red flags” with Theriot. 

Webre said Theriot did not have a police record in Ascension Parish, but he did have run-ins with law enforcement in St. John, St. Charles and Jefferson Parishes.

“He was not on our radar screen in Ascension Parish,” Webre said.
