Many knew Captain Rick Duncan to be a retired U.S. Marine, and an outspoken veteran’s advocate. His real name is Richard Glen Strandlof. He’s facing five federal misdemeanor charges under the Stolen Valor Act. Prosecutors will try to prove he made up his entire military background.

His story could stir emotion in an audience. As a survivor of the 9-11 attack on the Pentagon, and of a roadside bomb in Iraq, Rick Duncan spoke with authority on military matters.

"I was pretty angry because he really strung us along," said Jose J. Barrera. Barrera worked with Duncan to help Colorado Springs veterans like himself. Duncan founded the Colorado Veterans Alliance, speaking up for homeless veterans and against the ongoing conflicts overseas. When Barrera found out Duncan's real name is Strandlof and that his past is likely fake, Rick Duncan became a disgrace.

"He deserves it. He deserves jail time," Barrera said.

Strandlof may indeed end up behind bars as the first person in Colorado facing trial under the Stolen Valor Act for allegedly claiming he earned combat medals including a Purple Heart.

"It's something to be proud of, but if you haven't done it, it's not something to be proud of at all," said PFC Nathan Crane.

Local veterans believe false claims of valor tarnish the value to those who can prove they've earned the recognition, and worry about what those claims could do to their public image.

"It makes everyone else look bad," Crane said.

Jose Barrera said he would testify against Strandlof if he could, and despite what he did to help local veterans, Barrera believes greater damage has been done.

"I don't think he has a chance,” Barrea said. “He's guilty."

Strandlof pleaded not guilty to federal charges Monday in court. If found guilty, Strandlof could get up to a year in jail and a $250,000 fine.
