In a tearful press conference, St. John The Baptist Parish Sheriff Mike K. Tregre said his officers were ambushed this morning, resulting in the deaths of officers Brandon Nielsen, 34, and Jeremy Triche, 28.
The early-morning incident began when "a gunman opened fire" on an officer working traffic detail at the Valero plant parking lot in the area.
Officers Scott Boyington and Jason Triche were injured in today's shooting.
During the course of this morning's investigation into the first shooting that injured Boyington and Jason Triche, Neilsen and Jeremy Triche were led to a trailer where a second shooting happened.
As the officers were interviewing two people outside the trailer, a third person left the unit with an assault weapon and "ambushed my two officers," Tregre said.
While he wouldn't give many details, Tregre, who has been sheriff for only 45 days, said the investigation is ongoing.
"It's been a very difficult day," Tregre said in the news conference, which was broadcast by WWLTV.
The investigation began when two police officers were shot this around 5 a.m. near a Valero plant parking lot in Laplace, La., WWLTV reported the time.
Plant workers were evacuated after the shooting. A twitter feed that monitors police scans suggested early this morning that the suspect had been armed with an AK47. That specific model has not been confirmed.
Earlier reports stated two officers and two civilians had been shot. That has been updated to say two officers died and two officers were shot.
Police confirmed to WWLTV that two suspects are in custody and one suspect is still at large.
