U.S. Louisiana shootings leave 5 dead, suspect at large

A manhunt is underway in the southeastern U.S. state of Louisiana for a man suspected in shootings that have left five people dead, local authorities said Saturday.

Dakota Theriot, 21, is wanted in connection with the shootings, authorities said.

Ascension Parish Sheriff Bobby Webre told a news conference that deputies were called to a trailer in the city of Gonzales, about 40 kilometers southeast of Louisiana's capital Baton Rouge, for a "domestic incident" on Saturday morning. Upon arrival, deputies found Elizabeth and Keith Theriot, both 51, who had been shot but were still alive.

Webre said deputies were able to interview one of the victims before they were transported to a hospital in Baton Rouge, where they later died.

From that interview, authorities identified the couple's 21-year-old son, Dakota, as the "prime suspect in this case." He is being sought on first-degree murder and other charges.

The sheriff said three other shooting deaths occurred Saturday in neighboring Livingston parishes, about 50 kilometers east of Baton Rouge.

Livingston Parish Sheriff Jason Ard confirmed on Facebook that three deaths happened in his parish and identified the victims as Billy Ernest, 43; Tanner Ernest, 17; and Summer Ernest, 20.

Authorities believed the shootings in the two parishes are connected, and investigators from both jurisdictions are working together.

Theriot is considered armed and dangerous, Ard said. He is believed to be driving a gray four-door 2004 Dodge pickup with a silver bottom.
