Amy Carlson, who played Linda Reagan on the hit show "Blue Bloods," did not renew her contract after season 7, leading to the decision to kill off her character. In season 8, it is revealed that Linda died in a helicopter crash while airlifting a patient, but later it is discovered that a cartel ordered the hit on her. Carlson expressed disappointment with how her character's death was handled, but acknowledges that there is little chance for a return. However, fans would likely welcome her back in a flashback sequence.
