Who called from 6613994567

Has called a couple times never say anything when i call back it said that the number was no longer in service.
coming up on my phone ID as Kevin L. McElwee

Received call--didn't answer, left no message.  I called back, number not in service...spoofed call

Called about 4 times and finally I answered and a woman said " you're gonna die!"  scared the hell out of me

I got the same message , you're gonna die !?

I received a call at 6:30pm.  After answering the call, the line was silent for about 30 seconds and then an automated female voice said "goodbye".
