A man initially called a person of interest in the death of a pregnant Arlington mother of three in June is now charged with two counts of murder.
Roommates found 23-year-old Felicia Burney stabbed to death inside her home in the 8300 block of Berry Avenue. Burney had three preschool age children and was 8½ months pregnant.
A few blocks from the homicide scene, police arrested Andrew King, 24, on unrelated charges. Wednesday night, Channel 4 learned King has been charged with murder in the case.
Police said DNA evidence on the weapon used to kill Burney matched that of King.
They said King had been dating Burney's roommate and thought Burney was interfering with their relationship.
King had been on probation for kicking in a door at Burney's home in May. Police said King had been acting hostile toward Burney, and she had been in fear for her life because of his aggressive behavior.
During the hours before Burney was killed, police said King was standing outside in front of the house walking up and down the street and trying to make contact with his girlfriend, who was inside the house with Burney.
Police said King entered the home using a set of house keys, which were found near the back door.
Police said King stabbed Burney in the neck and chest with a knife. They said the killing was the result of a conflict that escalated.
