The 19-year-old man charged with fatally stabbing Dennis Lane allegedly told investigators that his girlfriend had instructed him to kill her father and his fiancee, specifying the number of times each was to be stabbed in the throat — 10 for him and 15 for her.
In a conversation at school hours before the Ellicott City blogger and businessman was killed, Jason Anthony Bulmer said, 14-year-old Morgan Lane Arnold told him "I don't know what I'll do if you don't do it tonight," according to charging documents released Monday.
Bulmer sent her a picture of a kitchen carving knife before he entered through a sliding glass door that she had left unlocked, police said. "Arnold gave a reply that indicated to Bulmer that this knife was satisfactory," Det. Donald Guevara wrote in the court papers.
The documents offer the first indication that Denise Geiger also was targeted in the attack early Friday on Lane, which shocked local residents and those who knew Lane and his daughter. Arnold and Bulmer are both charged with murder, and made their first court appearances Monday. Both will continue to be held without bail.
According to court records, Arnold had a rationale for killing Lane and Geiger. "I have my reasons and I'll tell you later," she allegedly told Bulmer, who relayed the conversation to investigators asking about the difference between the number of times each victim was to be stabbed. Afterward, Arnold promised the pair would run away to California, Bulmer allegedly told police.
But Geiger survived, and the charges don't indicate she was harmed. She called police from the Ellicott City home she owned with Lane and reported her fiancee was struggling with Bulmer. By the time police arrived, according to the documents, Lane was dead in one upstairs room, Bulmer and Arnold were in another, and Bulmer's hands and clothes were bloodied.
The charging documents refer to a string of communications between the two students in the days and hours before the killing of Lane, a prominent community member in Howard County.
Police said Bulmer gave them an account of the plot after he was arrested and waived his right to remain silent. Even before being transported to police headquarters, Bulmer told police at the home that he had killed Lane and that Arnold had told him to do it, according to the documents.
Bulmer also told police the plot had been unfolding for months, but "communications concerning the murder became more frequent within the past several weeks," the detective wrote.
In one of the more chilling allegations in the documents, police said Arnold told Bulmer there weren't any sharp knives at her home.
The two Mount Hebron High School students appeared separately in court Monday via video link from the Howard County Detention Center.
Arnold will remain in custody after her public defender waived her right for a bail review hearing. She appeared in a yellow jumpsuit and spoke little. Asked her name by the judge, she replied, "Morgan." Her face reddened as the hearing went on, her arms shackled and folded in front of her.
Arnold's mother, Cindi Arnold, was in the front row of the courtroom but declined to speak to reporters. A public defender assigned to Morgan Arnold's case could not be reached.
Bulmer, who appeared in a sleeveless blue smock that revealed a large tattoo on his right biceps, was denied bail by District Judge Mary Reese. A prosecutor described him as a danger to the community, himself and witnesses in the case.
Bulmer's public defender described him as a sophomore in high school who lives with his mother and has few financial resources. His attorney also said he had moved to Maryland four years ago.
Gary Bulmer, Jason's father, who lives in Plymouth, Mich., and is divorced from the teenager's mother, described his son in an interview as a gentle young man who had trouble with schoolwork but with whom he has a good relationship.
"He's a good kid, but he's slow in school and can't finish high school," said the father. "He gets along fine with other kids."
Gary Bulmer said he hasn't met Arnold but heard about her from his son and had concerns about the age gap between the two teenagers.
"He tells me he likes her, wants to be with her," the father said.
Gary Bulmer said it has been about two years since he has seen his son and that he and his now ex-wife split about six years ago. He said he didn't understand how his son could get involved in such an incident.
Other relatives of Jason Bulmer couldn't be reached to comment.
Geiger did not return a request for comment Monday. She had called police sometime after 4 a.m. Friday. Once there, police arrested Bulmer and put Arnold in "investigative detention" as they sorted out what had happened. Arnold was arrested a short time later.
According to the charging documents, Bulmer and Arnold would be in touch many times early that morning, until Bulmer let Arnold know he had left his home near Ellicott City's Normandy Shopping Center for her father's house.
Bulmer and Arnold are now charged with conspiracy to commit murder, first-degree murder and second-degree murder. At Mount Hebron, other students are being offered counseling.
Prosecutors declined on Monday to comment on whether Arnold gave a statement to police.
In the historic district of Ellicott City on Monday, business owners along Main Street recalled seeing Lane regularly, sometimes with his daughter.
"He seemed to get along with a lot of people," said Barry Gibson, whose wife owns The Forget-Me-Not-Factory, a shop brimming with tiny fairy figurines, stuffed unicorns and countless other items depicting mythical creatures. "He liked to kid around a lot."
Gibson is known for putting on bubble displays outside the store, and remembered Morgan — "a pleasant kid" — playing with the bubbles when she was a few years younger. She also enjoyed the items in the store.
"She was into the fantasy thing," Gibson said. "We have fairies, dragons, wizards, mermaids."
Gibson hadn't seen father and daughter together for at least a year, but would spot Lane in downtown Ellicott City every couple of weeks, Gibson said.
"It's just really hard for me to understand what happened," Gibson said. "He was the kind of person that would try to make things right, and work things out."
