Howard County girl to be tried as an adult in the death of her father

ELLICOTT CITY, Md. - A Howard County Circuit Court judge has ruled that a teen will be tried as an adult on charges she planned along with her boyfriend to kill her father, according to the Howard County State's Attorney Office.

Morgan Arnold , 16, allegedly planned the stabbing death of her father, Dennis Lane, inside their Ellicott City home in May of last year.

Arnold’s boyfriend at the time, Jason Bulmer, pleaded guilty to killing Lane and was sentenced last month. He admitted to stabbing Lane repeatedly.

Prosecutors allege Bulmer and Arnold planned the murder for months so they could run away to California together.

Arnold is set to go on trial beginning Aug. 18.
