CENTENNIAL, Colo. -

Attorneys in the Colorado theater massacre are returning to court for a hearing on whether testimony on fingerprint comparison should be allowed at the trial.

Monday's hearing is one of the last scheduled before James Holmes goes on trial in December on multiple charges of murder and attempted murder. Schedule changes have been common, however.

Holmes pleaded not guilty by reason of insanity in the 2012 shootings, which left 12 dead and 70 injured. Prosecutors are seeking the death penalty.

Attorneys for the University of Colorado and for a potential trial witness are also expected to be in court Monday fighting defense subpoenas for unspecified university records. Holmes attended the university before the shootings.

The nature of the records and the identity of the witness haven't been released.
