Search on for man suspected in five deaths

NEW ORLEANS (AP) – Authorities in Louisiana in the United States (US) said they are searching for an “armed and dangerous” 21-year-old accused of killing his parents and three others in two separate but related shootings last Saturday.

Authorities say Dakota Theriot first shot and killed three people – the woman believed to be his girlfriend, her brother and father – in Livingston Parish before taking her father’s truck, driving to neighbouring Ascension Parish where he shot and killed his parents.

“We are totally focussed on finding him. We’re following every lead that we come up with,” said Livingston Parish Sheriff Jason Ard during an evening news conference streamed online.

Theriot was being sought on first-degree murder and other charges.

He was believed to be driving a stolen 2004 Dodge Ram pickup, gray and silver in colour. Authorities have identified the victims in Livingston Parish as Billy Ernest, 43; Tanner Ernest, 17; and Summer Ernest, 20. Ard said Summer Ernest and Dakota Theriot were in a relationship and that Theriot had been living with her family for a few weeks.

But he said after talking with Summer’s mother, there was no indication of any red flags ahead of Saturday’s multiple shootings.

Authorities earlier identified the other two victims as Theriot’s parents – Keith, 50, and Elizabeth Theriot, 50, of Gonzales.

They were shot in their trailer last Saturday morning.

“The father was gravely injured at the time we found him and has since passed away,” said Ascension Parish Sheriff Bobby Webre.

But before he died, Webre said authorities were able to get a “dying declaration from him, and only enough information to let us know that it was his son that committed this act.”

Webre said there were indications that Theriot was travelling east and maybe was in another state by now.
