ARMED & DANGEROUS: Cops on hunt after man allegedly kills 5, including his parents, in shootings after argument with girlfriend

Authorities in Louisiana are reportedly looking for a 21-year-old man suspected of carrying out a deadly shooting spree that left five dead on Saturday.

According to WAFB, Dakota Theriot was allegedly behind the wheel of a 2004 Dodge Ram that took him to Livingston Parish and Ascension Parish this weekend where he carried out separate attacks. Investigators have launched a manhunt for Theriot and have circulated images of the pickup truck with tags that read C583809.

The first shooting occurred at about 9 a.m. at a mobile home park in Livingston Parish. Investigators responding to that scene reported that 43-year-old Billy Ernest, 20-year-old Summer Ernest and 17-year-old Tanner Ernest were found dead of gunshot wounds.

Another homicide was reported a short time later in the neighboring parish and offices found a husband and wife, both 50, dead in their bedroom. Keith and Elizabeth Theriot were identified by authorities as the suspect’s parents.

Early reports indicate the two crimes are believed to be connected and to have been committed by the same subject, as reported by Huffington Post.

Officials believe the deadly spree was motivated by a domestic dispute involving his girlfriend and the other victims of the first shooting.

Theriot, described by police as armed and dangerous, is wanted on suspicion of criminal offenses including first-degree murder, home invasion and illegal use of weapons. Police believe he could be on his way to Mississippi.

Livingston Parish authorities say anyone with information related to the case can leave a tip by calling 225-686-2241 or the Crime Stoppers hotline at 225-344-7867.
