A Fort Collins woman is wanted for arrest on suspicion of perjury after lying on her red flag petition against the police officer who killed her son.

The Larimer County Sheriff’s Office issued the warrant for Susan Holmes on suspicion of first-degree perjury and attempt to influence a public servant, spokesman Jered Kramer said. Holmes has not been arrested, Kramer said.

Online court records show the warrant was issued Jan. 23, one week after Holmes appeared in court to argue that the state confiscate Colorado State University police Cpl. Philip Morris‘ guns for a year. Morris shot and killed Holmes’ son, Jeremy Holmes, in 2017. The warrant was first reported by The Coloradoan.

Susan Holmes said on the petition that she and Morris shared a child together. In an interview with The Denver Post, she said that wasn’t true but that she had a legal theory she planned to use to justify her statement. She declined to explain the legal theory.

Under Colorado law, only family and household members as well as law enforcement officers can file red flag petitions.

A Larimer County judge on Jan. 16 denied Holmes’ petition because she didn’t have a legal standing to file the petition.

Kremer said he could not release the affidavit explaining the reasons for Holmes’ arrest. Holmes’ bond was set at $5,000.

Holmes did not immediately return a reporter’s call Thursday.
