after a domestic dispute involving Lana, the NYPD had taken her husband's police-issued weapon and he was ordered to turn over all guns in his home due concerns about his behavior, but he was not charged with a crime because Lana was not seriously injured. They say he was, instead, given a "do not harass" order telling him to behave himself. Lana is survived by a daughter.
