A woman faces 34 felony counts of forgery over accusations she faked signatures on petitions that put U.S. Senate candidate Jon Keyser on the Republican primary ballot.

Maureen Marie Moss, 44, was arrested Wednesday, after three district attorneys filed charges against her.

The investigation came after Marshall Zelinger, a reporter with 7News in Denver, tracked down voters who said they had not signed petitions for Keyser. Zelinger found one signature was from someone who was dead.

The report also sparked a debate over the role a candidate plays in determining the validity of signatures. Paid aid signature gatherers sign an affidavit attesting that all of the signatures are real, and a notary public must witness petitions being signed.

Despite that process, prosecutors say at least 34 signatures turned in by Moss were faked.

“I appreciate law enforcement acting swiftly to apprehend this woman so justice can be served,” Keyser tweeted Wednesday.

Keyser is one of four candidates who petitioned onto the GOP Senate primary ballot. Regardless of whether the signatures forged were needed for Keyser to get on the ballot, it appears he will remain in the race.

Darryl Glenn, an El Paso County commissioner, went the caucus route and was the only candidate at the state assembly to win enough votes to appear on the ballot.

The four other candidates collected 10,500 signatures, at least 1,500 of which came from each of Colorado’s seven congressional districts. The signatures had to come from registered Republican voters living in the district. The petition gatherer also had to be a registered Colorado Republican. Also, an individual’s signature could only be counted by one candidate.

Keyser had to file suit against the secretary of state and challenge a number of signatures deemed invalid because the gatherer was not a registered Republican. Keyser’s attorney showed in court that the petition gatherer, someone other than Moss, was a registered Republican, and Keyser was put on the ballot.

Candidate Jack Graham, a former Colorado State University athletic director, was the first to turn in signatures and qualified without issue.

Candidates Robert Blaha, a Colorado Springs businessman, and Ryan Frazier, a former Aurora city councilman, also sued to qualify for the ballot.
