CAUGHT ON VIDEO: NM trooper fires at minivan full of children

TAOS, NM (CNN) - Newly released police dashboard camera video shows how a simple traffic stop led to police firing at a minivan full of children.

The Tennessee mother who was driving that minivan and her 14-year-old son are now facing charges in New Mexico.

And the state police officers involved are under investigation.

"You're doing 71 back there in a 55, OK?" Orianna Farrell and a state police officer are arguing over a ticket just south of Taos.

"I'll be right back, go ahead and turn the vehicle off for me."

But as the cop walks off, Farrell does the opposite and pulls away instead.

So he pulls her over again. This time, the officer isn't too happy.

"Get out of the vehicle! Get out of the vehicle right now!"

In the video, you can see the officer try to pull Farrell out while the five kids inside scream.

"Leave my mom alone!"

Her 14-year-old son gets out, but thinks again when the officer pulls his taser.

The struggle continues.

"You're already facing evading charges right now, you ran away from me, OK?"

"Sir, I pulled back over. I didn't run away. You see my children, I'm not doing anything wrong, I'm just trying to take them to the Rio Grande."

Finally, Farrell agrees to get out and talk, but the conversation doesn't last long.

"Turn around and face your vehicle. Ma'am listen to me."

Farrell and the cop struggle as she tries to get back into the van.

While that happens, the 14-year-old gets out again. And this time he rushes the officer, trying to defend his mom.

After a short tussle, the boy runs back into the minivan.

The officer tries to get him out while backup arrives.

"Open the door! Open the door!"

Farrell starts to drive off, while another officer fires at the minivan full of kids as young as six.

Farrell then takes them on a four-minute high speed chase into Taos, cutting into wrong way traffic before eventually pulling over and giving up in front of a hotel.

She and her son are arrested.

According to the Taos News, the family is from Tennessee and was taking an educational road trip in New Mexico.

The mom is charged with child abuse, fleeing from police as well as a misdemeanor for possession of drug paraphernalia.

Her son is charged with battery of an officer.
