A Three Forks man convicted of trying to burn down his estranged wife's home in 2010 is back in jail after probation officers said they found guns, ammunition and alcohol in the home he was staying in.

Robert Howard Mock, 43, appeared in Gallatin County District Court on Thursday afternoon where District Judge John Brown set his bail at $500,000.

In 2012, Mock was sentenced to 34 days in jail followed by a 12-year suspended prison sentence after pleading no contest to three felonies: arson, stalking and theft.

Mock was charged with the crimes after a standoff outside his Madison Road ranch on Dec. 13, 2010, shortly after he tried to set fire to his wife's home in Three Forks.

In 2011, Mock's case was transferred to New Mexico. However, on Dec. 17, Mock's supervision was transferred back to Montana. Soon after, the Gallatin County Attorney's Office filed a petition to revoke Mock's suspended sentence.

Probation officer Jared Poole alleged in his report that less than 24 hours after being transferred back to Montana, probation officers found a handgun, two shotguns, a rifle, a large amount of ammunition and two knives in Mock's vehicle, his home and the home's garage.

Mock told probation officers the guns and ammunition were his father's, Poole wrote, and probation officers also found 11 bottles of wine and a bottle of whiskey in Mock's car.

After the alleged violations, probation officers jailed Mock. On Dec. 19, Mock's bail was set at $100,000 in Gallatin County Justice Court. Mock posted bail the same day.

On Dec. 26, after a breath test was positive for alcohol, Mock admitted to drinking from a gin cocktail that belonged to his father, Poole said. He has been in the Gallatin County jail on $150,000 bail since.

Mock's actions are concerning, Poole wrote. Despite being informed of the rules of probation multiple times, Mock continued to violate the conditions of his release, Poole said.

“It appears he just does what he wants,” Poole wrote.

During his court appearance Thursday, Mock denied all the allegations.

Citing Mock's original charges as well as the new alleged probation violations, Gallatin County Deputy Attorney Erin Murphy requested the $500,000 bond.

“The state believes this defendant is a serious danger to the community,” Murphy said.

Defense attorney Christopher Williams requested a $50,000 bond in hopes of Mock being released and getting into a 30-day rehab program.

If Mock's suspended sentence is revoked, he faces up to 12 years in the Montana State Prison.
