ELLICOTT CITY, Md. (AP) -- Howard County police say a 14-year-old girl and her 19-year-old boyfriend have been charged with murder in the stabbing of the girl's father.
Police found 58-year-old Dennis James Lane dead of multiple stab wounds in his Ellicott City home about 4:20 a.m. Friday.
Friday afternoon, Morgan Lane Arnold and her boyfriend, Jason Anthony Bulmer, were charged with first- and second-degree murder. Arnold is charged as an adult.
Police say the two teenagers used electronic communication to discuss killing Lane. Investigators believe Arnold left a basement door unlocked so Bulmer could get into the house.
Officers say Arnold encouraged Bulmer to stab her father in an upstairs bedroom. Police say another adult in the home heard noise and called 911.
Authorities say it is unclear what motivated the crime.
