Louisiana shootings leave 5 dead; manhunt underway for suspect

Both the Ascension Parish and Livingston Parish sheriff's offices are searching for Dakota Theriot, 21, in connection with the shootings.

Police said his dad was still alive when they arrived at the house and claimed Dakota was the gunman.

Webre called the first incident a case of domestic violence and said that Dakota Theriot was recently asked to leave the residence and not return.

A manhunt is underway in Louisiana following a string of shootings that left the suspect's parents and 3 others dead, law enforcement officials said. "We feel that they are related", Webre said. Those victims were identified by Livingston Parish Sheriff's Office as Billy Ernest, 43; Tanner Ernest, 17; and Summer Ernest, 20.

Ascension Parish Sheriff Bobby Webre says Dakota Theriot is the "prime suspect" in the deaths of Keith and Elizabeth Theriot of Gonzales, his parents.

Dakota Theriot, is suspected of killing two people in Ascension Parish and three people in Livingston Parish, which are just east of the state capital, Baton Rouge.

The Livingston Parish Sheriff's Office did not immediately respond to PEOPLE's request for comment.

The victims were not relatives of the suspect but appeared to know him. The victims, Billy, Summer and Tanner Ernest, were found dead Saturday morning, the Livingston Parish Sheriff's Office said.

In May, he shared a post saying "If you have a problem with me, tell me".

Dakota Theriot is also suspected of killing three more people less than 30miles northeast in Livingston Parish.

Authorities believe the two shootings are connected. The victims were identified as a husband and wife.

Theriot has been charged with two counts first-degree murder, illegal use of weapons and home invasion, according to a statement from the Ascension Parish Sheriff's Office.

Ascension sheriff's spokeswoman Allison Hudson says authorities believe the shootings in the two parishes are connected, and investigators from both jurisdictions are working together.
