TULSA, Okla. (AP) - A detective has testified that one of two Oklahoma teenagers charged with fatally stabbing their parents and three siblings indicated that he and his brother wanted to outdo known killers and hoped for publicity.

Detective Rhianna Russell of the Broken Arrow Police Department testified during a hearing Tuesday that Michael Bever mentioned the Columbine school and Aurora movie theater killings in Colorado in particular.

Nineteen-year-old Robert Bever and 17-year-old Michael Bever have pleaded not guilty to first-degree murder. Tuesday's hearing is for the judge to determine if there is enough evidence to proceed with a trial. Two siblings survived the rampage

Detective Eric Bentz testified that Robert Bever lamented that the plan didn't go as they were supposed to and "everyone didn't die like they were supposed to."
