From the Chicago Tribune article cited above: "Hoping to get better information, the Shieldses are in New York, where they've been in contact with a New York police captain, they said.
Although the couple characterized the investigation as 'very guarded,' Donna Shields said the captain has been 'just incredibly helpful.'"
If the family feels that NYPD is being "very guarded," that suggests to me that they don't just see this case as a likely suicide-and that another or others are involved in Sierra's disappearance. And that the family says that Sierra "had no current romantic involvement" makes me want to know: who was she involved with previously? And where is that person--or where are those persons?
Further:
According to Donna Shields, her daughter's supervisor at Shuttle America said she hadn't seen her since Sierra asked to talk to a union representative. Donna Shields said she and her husband are "still trying to determine" what the issue was. "Her supervisor doesn't know why; we don't know why," she said.
This seems odd to me. I'm a former flight attendant for a different airline. If Sierra was so upset about something that she went to see her supervisor and then asked to see her union rep--yet no one else seems to know on what grounds--I am concerned that she was being somehow harassed at work by someone who was not a member of her union. If she were in trouble for something at work, I would think she would have confided in someone--a more senior f/a, a roommate, her pastor. Reports say that she went to see her supervisor the same day she was scheduled to work a trip. When I flew, if a flight attendant was called on the carpet, she arranged for a rep to accompany her to see the supe--she wouldn't just go in alone. It is not an informal meeting. Airline crews are quasi-military in their structure. She would ask the rep directly to come with her, not ask the supe if she could speak to a rep. These are Teamsters. They take the welfare of their members very seriously. If she went in for something benign, and suddenly the supe said, “Sierra, we've had a complaint about you” (or whatever negative scenario), she would have done what she learned in her f/a training class to do: immediately stop the conversation and say, Ms. Supe, I will need to consult with my union rep and bring him/her to our next meeting. (It's like on cop shows: I want a lawyer.)
It has been reported that Sierra quit her job in that meeting, yet the supervisor doesn't know the issue? Doesn't sound right to me.
