Police are questioning a New York City woman in the fatal stabbing of her 18-year-old son.
Media outlets report Yvonne Hines was being questioned Saturday in the death of her son Sean at the family's apartment on Manhattan's Upper West Side.
Police said the woman and her son had fought violently in the past. According to The New York Times, Commissioner Raymond Kelly says both were arrested after a fight in June.
Authorities say the stabbing was reported late Friday night by the victim's stepfather. Witnesses told The New York Post that Yvonne Hines denied killing her son as she was led away and blamed her husband, who was also being questioned.
