(CBS4) – A 34-year-old Loveland man who investigators believe wasn’t at the scene of the shooting of postal worker Jason Schaefer but is complicit in the crime was charged with first-degree murder on Tuesday. The suspected shooter, Schaefer’s ex-girlfriend Devon Schreiner, also faces a first-degree murder charge. Andrew James Ritchie was arrested last week and he had a hearing in Boulder County Court on Tuesday.

Schreiner and Schaefer were involved in a longstanding custody battle over their child. Both had worked for the U.S. Postal Service in Longmont but Schreiner was fired about two weeks before the deadly shooting. She had recently started working for the U.S. Postal Service in Loveland.

According to the arrest affidavit, police believe Ritchie and Schreiner had been in a relationship. Ritchie told police that he and Schreiner were just friends but that she wanted more and he didn’t want to be in a relationship with her.

Ritchie told police that he had traveled to Longmont on Oct. 13 to find Schaefer to try to warn him about Schreiner’s plan to hurt him, according to the arrest affidavit. When police asked why he didn’t call police if he thought that Schreiner would hurt Schaefer and he said that “he did not know if she was serious.” He also told detectives that the threats to harm Schaefer had been going on for a while and they didn’t seem as serious on previous occasions “except for the three days before the shooting when Schreiner messaged him a picture of herself dressed in clothes similar to those of the shooting suspect.”

Ritchie is currently being held in the Boulder County Jail.
