On a November night in 1983, Colorado Springs police answered a call from a father who said he had been struck in the face by his son, a senior in high school a month past his 18th birthday.

That young man was Darryl Glenn, according to a police report and other documents obtained by The Denver Post. Glenn, who is running for the U.S. Senate, has said he has no knowledge of the incident and that it may have been someone else — either his half-brother or another person named Darryl Glenn.

When The Post presented the candidate with the documents this week, his campaign spokeswoman said Glenn had no recollection of any run-ins with police. His responses to inquiries from reporters about the assault charge have been inconsistent.

In May, before The Post obtained the detailed police report, Glenn told the newspaper he has never been interviewed by police for any reason. He said the charge might have involved another man named Darryl Glenn and that he sometimes gets phone calls about that person.

This month, Glenn told the Colorado Springs Independent the case might have involved his half-brother, Cedric, who was 8 years older than Glenn and died in 1992. He said Cedric had a “criminal past.” Glenn pointed out that he is an Air Force Academy graduate and that he would not have been accepted as a cadet had there been questions about his past.

The Post supplied Glenn’s campaign with the police report and court documents this week.

“Darryl has never been arrested, never even been questioned by the police, and doesn’t know what actually happened,” his spokeswoman, Katey Price, said in an e-mail Monday. “There’s nothing inconsistent because in both instances, he was speculating on what might have happened.”

The campaign would not make Glenn available to discuss the police report.

The police report shows the victim was Ernest Glenn and his assailant as Darryl Lemon Glenn.

Records show Glenn, or someone claiming to be him, appeared in court to be advised of the charge in December 1983, three weeks after the alleged assault. Two months after that, in February 1984, the charge was dropped after Ernest Glenn chose not to pursue it.

Ernest Glenn died in 2006, records show.

The 1983 complaint has a signature of the name Darryl L. Glenn that has similarities to signatures on Glenn’s business and campaign documents dating to 2000.

Wendy Carlson of America’s Handwriting Expert LLC in Denver, who examines legal and business documents and trains election workers to spot forgeries, cited similarities between the two Glenn signatures.

“I believe it’s the same person who signed both,” she said Tuesday.

The court documents from the alleged assault case also include Glenn’s date of birth, a Social Security number, his physical description and that he was a student at Doherty High School. Public records show Glenn lived at his family’s Colorado Springs home at the time.

Glenn was a national collegiate power-lifting champion at the Air Force Academy, a distinguished airman, an El Paso County commissioner and the Republican nominee to face Democratic incumbent U.S. Sen. Michael Bennet. Glenn has campaigned on his honesty and integrity.

Glenn’s response to inquiries about the incident surprised independent Colorado political analyst Eric Sondermann.

“It strikes me as a classic example of the coverup being worse than the offense,” Sondermann said.

“No reasonable voter would judge someone based on what happened in 1983, before that person was even a young man,” he said. “We all did things we wish we hadn’t. … But while voters might not judge him based on what happened in 1983, they can judge how he handles it now — does he own up to it, does he take responsibility, or does he duck, dodge and weave?”

In June, Glenn shocked the Colorado Republican establishment by winning the primary among a crowded field, clinching the party’s nomination for the Senate. Last week, he spoke at the Republican National Convention.
