LA JOYA - State troopers and the Guatemalan consulate are providing conflicting statements regarding a shooting that left two immigrants dead.

The shooting happened Thursday near Mile 7 and Jara Chinas Road. A state trooper in a helicopter opened fire on a truck involved in a pursuit.

Two people in the truck were killed and a third was wounded. Troopers say they thought the truck was carrying a covered load of drugs.

Monday, the Guatemalan consul said survivors of the shooting claimed the tarp flew off the bed of the truck. They told the consul they waved at the helicopter to stop shooting, but the trooper continued to fire.

In an updated statement, troopers wrote, "According to our preliminary review and irrefutable evidence.... the tarp did not blow off the back of the truck during the pursuit."

CHANNEL 5 NEWS asked troopers for more information about the irrefutable evidence. We're waiting to hear back from them.

Meanwhile, several civil rights groups will be holding a press briefing tomorrow near the scene of the shooting. It's scheduled for 2 p.m. at the intersection of Jara Chinas and Mile 7.

They say speakers from different groups will talk about public safety, government accountability, and use of force policies, while also demanding a full investigation into the incident.

Texas Rangers say their investigation into the case is ongoing.
