Louisiana State Trooper Lay Dead in His Patrol Car for Hours Before Being Discovered

Master Trooper Adam Gaubert was killed early Saturday, but was not discovered until 5 p.m. due to a "chaotic situation," the Associated Press reported.

Gaubert was shot to death in an ambush Saturday morning after he worked on a traffic crash.

According to Superintendent Lamar Davis, Gaubert was one of two victims allegedly killed by Matthew Mire, 31, who was captured Saturday night. Davis said that a policy of using radio communication for emergency messages only during that time could have been part of the reason Gaubert's death was not known earlier.

"The time between the murder of Master Trooper Gaubert and the time he was found is absolutely unacceptable," Davis said. "And the results of this chaotic situation contributed to just that. We are learning from this experience, we're getting better."

According to Davis, under ordinary circumstances, Gaubert's failure to give routine notice of going off duty would have been noted.

Davis called Gaubert a friend and a highly respected trooper and said efforts to improve procedures that caused the chaotic situation are already underway.

The exact time of Gaubert's death has not been determined, but Davis said camera footage obtained by investigators shows a truck that police said was stolen by Mire entering the area where Gaubert was parked about 2:30 a.m., more than 14 hours before the body was discovered.

The string of shootings that killed Gaubert and one other person is believed to have started in Livingston Parish about midnight Friday. Mire is suspected of shooting and wounding two people there before stealing a pickup truck.

Based on surveillance video, Davis said, Mire is believed to have entered the area where Gaubert was parked about 2:30 a.m. Saturday. Gaubert was not involved in the response to the Livingston shooting and is thought to have been finishing up a traffic crash report at the time.

Davis said police believe Mire went to the area to prepare for another attack in which a woman was killed and a man was wounded. The motives for all of the shootings remain unclear.

Mire exchanged gunfire with another state trooper who spotted the stolen truck about 5 a.m. Saturday, Davis said. He was captured Saturday night after a manhunt involving multiple agencies.

Mire was hospitalized with a bite from a police dog and a leg injury from what state police said was a suspected self-inflicted gunshot wound. He faces multiple charges in multiple jurisdictions, including the murder of a police officer.
