BOZEMAN, Mont. -

The father of a Gallatin County man wanted on a $500,000 warrant tells NBC Montana Matthew Brandemihl has disappeared.

Judge Holly Brown issued the arrest warrant after Brandemihl allegedly failed to meet with his probation officer.

Brandemihl burglarized a home north of Belgrade, stole three vehicles, and led police on a high-speed chase across two counties, ending with a surrender near Pony last spring.

On March 18, Judge Holly Brown sentenced Brandemihl to 10 years, with 10 years suspended, and ordered him to Gallatin County Treatment Court. But court documents say Brandemihl didn't report for his appointment on March 26 with his probation officer, and every attempt to locate him has been unsuccessful.

NBC Montana went to the apartment where Brandemihl was supposed to be staying, and where his father lives. Brandemihl's father, Dale Brandemihl, said he is worried about his son.

"I haven't seen him in about four days," Dale Brandemihl said.

According to Matthew Brandemihl's probation officer and his father, he is nowhere to be found and is skipping out on probation meetings.

"The situation he's in right now, there's nothing I can do," Dale Brandemihl explained. "I got him a job, he worked about a day and a half and, like I said, I haven't seen him."

In late March, court records say Brandemihl missed a meeting with a probation officer. The officer reports not being able to get in touch with him since.

Dale Brandemihl said he doesn't know where his son is either.

"I think they cut him slack, I'll put it that way. Ten years is quite a while and that's what he's looking at," he said.

Now, with a warrant out for his arrest, Matthew Brandemihl could be facing his full 10-year sentence.

"Nobody wants to see their kid go to prison," Dale Brandemihl said, "but if you don't do what you're supposed to do, that's what happens."

Dale Brandemihl said he thinks his son has prescription medication addiction issues, and was hoping treatment court would help turn his life around. Now, he is even more worried about his son's future.

"Everybody knows he's a pretty good kid," he explained. "But his other problems cause him problems."

He said his son doesn't have a car and very little money, so he believes he still may be in the area.
