Don't you hate it when this happens
My name is xxxx yyyyyyyy. I am an intern at Dateline NBC and I am currently doing research on stories similar to your sister's.
I would love to talk to you briefly and find out the status/any developments in your story.
Is there a number where I can contact you?
If it is preferred, you may contact me here at Dateline. The phone number is (818) xxx-xxxx.
Thank you. I look forward to speaking with you.
