Soldier who served with Matthew Riehl contacted law enforcement

GLENROCK, Wyo. -- Recent online postings by the man who killed a Douglas County sheriff's deputy on New Year's Eve convinced a solider, who served with Matthew Riehl in Iraq, to contact two law enforcement agencies in Wyoming.

Leon Chamberlain, 66, retired as a major from the Wyoming National Guard on Nov. 15.

He said in 2009 he was the only behavioral health officer in the Wyoming National Guard Unit that was deployed to Iraq.

He's the person Riehl would've been sent to see if Riehl had exhibited any signs of strange behavior, but Chamberlain said there wasn't any.

"No, never, I only saw positive things, only appropriate and professional behavior from him," Chamberlain said. "He was a good soldier."

Whatever troubled Riehl, Chamberlain doubts it had anything to do with his service in the Middle East.

But it was fellow service members who contacted Chamberlain in October, concerned about Riehl.

"Several of the guys had contacted me and said, 'Things don`t seem to be doing right. He's got a website and he's been putting some crazy stuff up there would you get a hold of him'," Chamberlain said.

Chamberlain wasn't able to reach Riehl on the phone but said he soon received a bizarre text.

"It was information that didn't make any sense. It was pretty perverse in nature and all," Chamberlain said.

That's when Chamberlain contacted police with the University of Wyoming who he knew were investigating Riehl for online rants against the university's College of Law and two of its professors.

On Nov. 6, the university put out an email, warning students and faculty about Riehl with a picture of the former student and his car.

Around the same time, Chamberlain said he received a disturbing Facebook message from Reihl, so Chamberlain contacted his local sheriff in Converse County, Wyoming.

"That's still a brother veteran and so No. 1, I wanted him to get help and No. 2, I didn't want other people to be at risk," Chamberlain said.
