Lancaster County, Pennsylvania: Lancaster Online reports that the attorney for 14-year-old Claire Miller, Robert Beyer, announced his intent to pursue a mental health or insanity defense in court filings earlier this month.


Beyer also filed a request that Miller's trial be moved from adult court to the juvenile court system. Under Pennsylvania state law, all homicide charges are automatically considered an adult crime.


Lancaster Online attempted contacted Beyer for comment on Thursday ahead of Miller's scheduled formal arraignment, but he declined to comment.


Miller will turn 15 tomorrow. She is currently being held in the State Correctional Institution at Muncy.


Following the stabbing death of her 19-year-old sister Helen on February 21 Miller was charged with a single count of homicide. Investigators stated at the time that she had spoken on the phone with someone earlier in the night and reported "suicidal and homicidal thoughts."
