A 14-year-old girl and her 19-year-old boyfriend arrested in the killing of her father in his Ellicott City home this month were indicted and charged as adults by a grand jury this week, according to court records.

Morgan Arnold, a Mount Hebron High School freshman, now faces two counts of solicitation of murder for allegedly asking her boyfriend, Jason Bulmer, to kill her father, Dennis Lane, and Lane's fiancee, Denise Geiger, according to her indictment.

Both Arnold and Bulmer, a Mount Hebron sophomore, are charged with first-degree murder in Lane's killing, and both are charged with two counts of conspiracy to commit murder for allegedly plotting the deaths of both Lane and Geiger, according to their indictments.

Joseph Murtha, Arnold's attorney, said Thursday he will petition the court to waive Arnold's case back to juvenile court, saying he has "grave concerns about her mental health and her ability to participate in her own defense."

Arnold has been diagnosed with Asperger's syndrome and an anxiety disorder, according to her mother and court records. Bulmer's father has described him as being "slow" in school.

The charges say the two teens "feloniously, willfully and with deliberately premeditated malice" killed Lane and plotted to kill Geiger.

Geiger called 911 from her and Lane's home early on the morning of May 10, police said. Officers who responded to the home found Lane dead from stab wounds in an upstairs bedroom and Bulmer and Arnold together in another, police said.

Geiger, who has declined to comment on the case, was unhurt.

After his arrest, police said, Bulmer told them that Arnold had asked him to kill her father and Geiger, specifically requesting that he stab Lane 10 times in the throat and Geiger 15 times in the throat.

The killing of Lane, a well-known businessman and blogger in the county, shocked neighbors and longtime friends.

Murtha, Arnold's attorney, said he is working to determine whether Arnold is competent to stand trial.

"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," he said.

Douglas Nelson, a state prosecutor in both Arnold's and Bulmer's cases, declined to comment.

Janette DeBoissiere, a public defender representing Bulmer, also declined to comment.

Scheduled preliminary hearings in Bulmer's and Arnold's cases in District Court will not proceed, said Wayne Kirwan, a spokesman for the county state's attorney's office. Arraignment dates in Circuit Court will be scheduled, he said.
