ELLICOTT CITY, Md. (WJZ) — A 14-year-old girl and her 19-year-old boyfriend have been indicted and charged as adults in the killing of her father in his Ellicott City home.
According to our media partner, The Baltimore Sun, Morgan Arnold’s attorney said he will petition to send her case to juvenile court because he has “grave concerns about her mental health and her ability to participate in her own defense.”
Arnold, a Mt. Hebron High School freshman, was diagnosed with Asperger’s and an anxiety disorder.
The charges said Arnold and sophomore Jason Bulmer, described as “slow” by his father, had “feloniously, willfully and with deliberately premeditated malice” and plotted to kill Dennis Lane and his fiancee, Denise Geiger.
Police said the daughter intentionally left the sliding glass door to their Ellicott City home unlocked last month so her boyfriend could enter in the middle of the nigh and stab her father to death.
During the attack, Geiger, who was unharmed, called for help. Bulmer was apparently covered in blood when officers arrived.
Bulmer later told police Arnold asked him to stab Lane 10 times in throat and Geiger 15 times in the throat.
“I’m very concerned about her mental health and the need to try to place this case in juvenile court, and to recognize the mental impairments that interfered with Morgan Arnold’s reasoned decision making,” said Arnold’s attorney.
Arnold and Bulmer are both charged with first-degree murder and two counts of conspiracy to commit murder.
