Another scammer calling on a holiday

Caller ID: Middle River MD (on first of 2 calls).  Called twice today within an hour, left no voicemail.  Blocked.

Robocall.  Answered but didn't speak.  Call terminated without calling party comment.  I suspect a "Fishing expedition," seeking to confirm someone is at home, to be followed by a Scam attempt from another telephone number.

Unknown number, "Middle River MD", did not answer, no message left. Assumed to be telemarketer.
