A man who allegedly pointed a gun at people in a grocery store parking lot and ran from police officers in August is one of three people accused of involvement in a Casper-area methamphetamine distribution ring.

Doyle Gabbert, 37, is accused of conspiring to deliver methamphetamine. He was arrested after a police chase through Casper in August.

In connection with the chase and another incident two days prior, Gabbert faces one count of aggravated robbery, three counts of aggravated assault, two counts of theft, one count of being a felon in possession of a firearm and one count of possession with a deadly weapon with intent to threaten the life of another person.

Prosecutors hope to apply the habitual criminal label in connection with the aggravated robbery and aggravated assault charges.

Tyrone Jackson, 46, is also charged with conspiracy to deliver methamphetamine. He pleaded not guilty Friday morning in Natrona County District Court. If convicted, he could face up to 20 years in prison and a $25,000 fine.

Robin LaRae Larson, 36, pleaded guilty Dec. 20 to one count of conspiracy to deliver methamphetamine, which could send her to prison for up to 20 years as well.

Court documents say agents with the Wyoming Division of Criminal Investigation began looking into a Casper methamphetamine distribution organization in the fall of 2015.

Agents identified Gabbert as a suspect in the trafficking ring, according to the affidavit. Investigators also learned Gabbert was suspected of firing a handgun at people in Casper in two separate incidents during the week of Aug. 8, 2016.

Shortly after the first alleged shooting on Aug. 10, Casper police officers found Gabbert's Jeep and stopped it near 11th and Payne Street. Larson. Gabbert's then-girlfriend, was driving the Jeep.

Detectives executed a search warrant on the Jeep and allegedly found three baggies containing 18 grams of methamphetamine in total, as well as a small scale. Court documents allege Larson got the methamphetamine from Gabbert.

A search of Larson's phone reportedly turned up text messages that indicated Larson sold methamphetamine. Police allegedly found several marijuana pipes in Larson's home.

Detectives learned Gabbert had dropped the Jeep off at Larson's house at about 4 p.m. that day. He said he needed to leave town after his anger got the best of him, court documents say, so Larson let Gabbert take her 2015 Nissan Xterra.

Gabbert wasn't in the home when police arrived. Officers continued to search for him for the next two days.

The next day, Aug. 11, detectives learned that Larson was driving the Xterra in the area of Fort Caspar Campground. Officers stopped Larson, who was with two other people at the time. She was arrested on a charge of felony methamphetamine possession.

And on Aug. 12, police were called about Gabbert allegedly pointing a gun at people in the Ridley's parking lot. Gabbert reportedly threw down a pistol as he took off.

As for Jackson, charging papers say he admitted on Oct. 13 to his probation agent that he had been selling methamphetamine and it was his only source of income aside from disability.

A confidential source told DCI agents that Jackson had sold one-gram quantities of methamphetamine numerous times from June through August 2016.
