A repeat offender is back behind bars four days after the U.S. Marshals Service issued an alert asking for help locating him for violating federal probation for a 2011 armed robbery in Happy Valley.

In addition to possible sanctions for violating federal probation, Kevin Kenneth Gaethle, 34, is facing a new felony charged in Flathead District Court for alleged failure to register as a violent offender.

Gaethle was booked into the Flathead County Detention Center on Thursday after being arrested by sheriff’s deputies.

“We got him,” Sheriff Chuck Curry said of Gaethle’s arrest on Airport Road outside Kalispell.

According to court documents, Gaethle was released from federal prison on July 24, 2015, and was told he must notify authorities within three days if he changed his address.

On March 16, a sheriff’s deputy found that Gaethle was wanted by federal authorities for probation violations. The deputy interviewed Gaethle’s father, who said Gaethle had not lived at the home since the end of January.

Gaethle is serving a three-year probationary sentence following a 51-month prison sentence for his role in an armed robbery in Happy Valley in 2011.

Gaethle allegedly told two others involved in the robbery where one of his victims had guns stored in a home.

His accomplices — Bradley Thompson of Kalispell and Steven Acton of Libby — entered the home and held a 16-year-old girl at gunpoint and made her take them to the gun safe.

After stealing guns and a small amount of marijuana, they left with Gaethle driving the getaway car. The criminals told investigators that they intended to sell the guns in Oregon to buy drugs. Acton was caught in Renton, Washington, with some of the guns.

Gaethle has a long criminal history that includes three felony convictions in Flathead County from 2005 to 2008 including two counts of criminal possession of dangerous drugs and one count of criminal possession with intent to distribute.

Felony bail-jumping charges were dropped against Gaethle as part of plea agreements where he was given suspended sentences for the drug-related crimes. The suspended sentences were revoked after Gaethle possessed ammunition and pepper spray, lied to a law enforcement officer, failed to remain law abiding and admitted multiple times to using drugs.

His arraignment is May 19 before Flathead District Judge Heidi Ulbricht.
