It depends. In murder investigations a detective usually wants to do that or give direction to who does it. If it is due to an accident or natural cause then usually the officer assigned that area/jurisdiction where the notification must be made gets the job. Sometimes in this instance a department affiliated chaplain may also be able to go.I once had to have our dispatchers notify parents via telephone their daughter had been gravely injured. I felt terrible but i had to do it. She had been hit by a car (vehicle vs. pedestrian) during a major traffic accident. We had to do it because after we found her gravely injured i found her car with an empty child seat in it. It was intensely foggy and we couldnu2019t find the baby. She didnu2019t have the baby with her. I felt horrible for having to do that. I later went to their home and explained why.No officer likes doing that or wants to do it. The pain of the loss for the now broken loved one sticks with you.
