Defense attorneys in the Colorado theater shootings have subpoenaed disciplinary records of a police officer from Aurora, the Denver suburb where the attack took place.

The subpoena, made public Monday, seek documents from a 2008 internal affairs investigation of officer Joshua Schol. The subpoena says that investigation concluded Schol was untruthful in a police report that is apparently unrelated to the theater shootings.

It wasn't immediately clear why the defense wants the records, but it could be to discredit Schol if he is a witness in the upcoming trial.

Aurora police didn't immediately respond to a phone call and email.

James Holmes is charged with murder and attempted murder in the July 20, 2012, theater shootings, which killed 12 people and injured 70. He pleaded not guilty by reason of insanity.
