A hearing to determine if a teenager charged with killing his parents will be tried as an adult will last at least one more day.

Andrew Balcer (BAHL’-sur) was in court Wednesday in Augusta, where officials are deciding on the case. He left the courtroom in the early afternoon to return to a juvenile detention facility and is expected to return Thursday.

Attorneys have said they expect the hearing to last two to three days.

Balcer is charged with stabbing Alice and Antonio Balcer to death a year ago. An interview with Balcer and detectives was played in court on Wednesday. In it, Balcer says he remembers most of what he did but doesn’t know why.

Court testimony has revealed that a Maine teenager charged with killing his parents told a police dispatcher he “snapped” on the night of the stabbings.

Andrew Balcer (BAHL’-sur) is in court Wednesday in Augusta, where officials are deciding whether to try him as an adult.

Balcer is charged with stabbing Alice and Antonio Balcer to death in their Winthrop home last Halloween. Balcer was 17 at the time and has since turned 18.

A 911 recording playing in court includes Balcer saying he stabbed his mother in the back before stabbing his father when he woke up from the screams.

Prosecutors filed a petition to have Balcer tried as an adult, but his attorney pushed back. If prosecutors are successful, he could face 25 years to life in prison on each count.
