ELLICOTT CITY, Md. (CBSDC/AP) — A teenage girl charged as an adult in her father’s stabbing death told her boyfriend she wanted him to knife her dad 10 times in the throat and planned to run off to California after the slaying, police said.

Morgan Arnold, 14, and her 19-year-old boyfriend, Jason Bulmer, had discussed a plot to kill Dennis Lane for two months, Bulmer told investigators, according to police charging documents released Monday.

“I don’t know what I’ll do if you don’t do it tonight,” Arnold told Bulmer the day before the killing, according to the documents.

Arnold and Bulmer are each charged with first- and second-degree murder in the stabbing death Friday of Lane, a real estate blogger in Ellicott City. Officers found the teenagers in an upstairs bedroom after a girlfriend of Lane’s who was staying at the house that night called police and said someone had come into the home and stabbed him.

Bulmer told investigators he sent Arnold a text message containing a photograph of a kitchen carving knife that he intended to use, and Arnold “gave a reply that indicated to Bulmer that this knife was satisfactory,” the documents said.

Arnold waived her right to a bail hearing in Howard County District Court on Monday. Bulmer was ordered held without bond.

A phone message left with the county public defender’s office, which is representing the couple, wasn’t immediately returned. The teens attend Mount Hebron High School.

Police say Bulmer told investigators that Arnold wanted him to stab her father in the throat 10 times and to stab Lane’s girlfriend 15 times while they were sleeping.

Bulmer said Arnold told him that she had her reasons for wanting each person stabbed a specific number of times.
