Police arrested a 19-year-old Torrington woman Tuesday, alleging she was drunk and high when she wrecked her car in November, killing her front-seat passenger.

Brianna Green faces one count of aggravated vehicular homicide for the death of Dallas Fierro, who was 19.

If convicted, she could face up to 20 years in prison.

The pair left a bonfire party together in the early morning hours of Nov. 19, with plans to meet up with people at Fierro’s house, according to an evidentiary affidavit filed in the case weeks before Green’s arrest.

A 911 call came into dispatch just after 4 a.m.

Goshen County Sheriff’s Deputy Jason Lamb was dispatched to the northwest corner of Road 74 and state Highway 159 in Goshen County. There he saw a 2008 grey Dodge Charger, wrecked from plowing into a metal corral fence on the north side of the road, says the affidavit and prior reports.

The fence was tough, made of drill stem and sucker rod, according to a Wyoming Highway Patrol report at the time.

Lamb noted the Charger was registered to Green’s mother.

Bad Tires

Rescue and emergency medical personnel and Torrington police officers also converged on scene to find Green sitting about 10 feet from the wrecked vehicle, bleeding from her head, says the affidavit.

Lamb approached to check on her and smell the surrounding air for the odor of alcohol. He did not smell alcohol, he’d later write.

Green said she was headed back from a bonfire with friends – the bonfire was “outside of town” and she said she didn’t know the address, says the document.

She said she knew her tires were bad. She said she was traveling at 40 mph and braked for the stop sign.

Via a warrant issued on the car’s on-board computer two weeks later, police discovered she was actually traveling 81 mph in the 35 mph zone just before braking, and she was traveling at 55 mph at the time of the crash, the affidavit says.

Green’s friends arrived at the crash scene and comforted her.


Lamb asked Green if she’d been drinking.

She had two Mike’s Hard drinks but wasn’t “drunk or buzzed or anything,” was her response, adding that she stopped drinking about two hours before the crash.

Lamb asked if she’d used marijuana.

Her response was that she was not distracted while driving, says the affidavit.

Green was taken to the hospital, where personnel reportedly drew and tested her blood.

Police served a warrant for the results of that test 10 days later and found her blood-alcohol level at the 6:45 a.m. blood draw was 0.102% blood-alcohol content, says the document.

Her blood also allegedly tested positive for THC (the psychoactive ingredient in marijuana and its variants) and opioids. The draw happened prior to the hospital administering any opioids, Lamb wrote.

‘Shut Down’

Lamb also interviewed at least two of Green’s friends.

Both a female and a male friend recalled Green parking on an embankment away from the bonfire because her tires were bad, the affidavit says.

The female friend, Molly Gesch, reportedly remembered Green calling her after 4 a.m. screaming, crying and telling Fierro to wake up.

Gesch was able to track the accident down because she had Fierro’s location enabled on her phone, the affidavit says.

The male friend, Nathaniel Vanrisseghem, told Lamb that when he got to the scene and saw Fierro unresponsive, he “shut down.”

Witnesses from the party recalled Green drinking Mike’s Hard drinks; and one said she took Jose Cuervo shots, the affidavit says.

Green's case is at the preliminary level in Torrington Circuit Court and is ongoing.
