Same here. Did not answer, they left no message. Same thing happened yesterday. Same thing in April, but # was 720-445-7739 on 4/21, and 720-259-8262. I don't know anyone in that area code and I think these calls are suspicious.

I had a missed call from this number on 19may16, no message was left. And who calls at 9pm? I live near the area code but do not have a phone number within the state.
