Received a call from this number at about 10:00 AM and they left no message. Suspicious because it came 10 minutes after I failed to pick up, then blocked, an unknown call from Florida. Found that both numbers came up on Google searches as harassing marketing or scam calls.
It's a guy named David Anderson who lives in Hollywood FL but went to Glennbrook North HS in IL. He's been harassing and threatening my mother and another man we spoke with in IL too. Report the calls to your local police department and press charges.
