About seven or eight years ago...
It was January and it was minus 20 degrees out. I looked out my window and a teenage boy was walking by with just slippers, pj bottoms and a tshirt on and he was kind of limping. I opened my door and called out to him, but he just kept going. He was heading towards the forest across the road. I grabbed the phone and called the police and tried to follow him, but by the time I got my coat and boots on, and got out the door I had lost him. Anyways, thankfully, the police found him in the forest and he was okay.
I called the police about a year or so ago for almost this exact same reason.
DH & I were watching TV ("The Walking Dead" of all things) very, very late one night (between 1:00 & 2:00 am) when our dog suddenly went crazy, running back & forth between the front door & the front living room window & barking - not his "there's a cat out there" bark but his "there's a stranger out there!" bark.
Across the street from us, there are two houses w/ a small wooded plot in between the houses - the wooded area is straight in front of our house, & a truck was parked in front of this small area. As we watched, a young-ish guy (older teens maybe?) got out of the truck & just kind of stood there while someone else took a couple of cardboard boxes out the back of the truck & tossed them on the ground beside the guy. The truck then drove off, leaving the guy standing there w/ the boxes.
The guy stood beside the boxes for a couple of minutes & then started walking, leaving the boxes. He walked down to the street corner & stopped at the stop sign & then just stood there.
We figured he'd been just dumped there by someone, & I was worried because it was freezing outside. DH was going to go to talk to him, but I also didn't want DH to get in the middle of some drug deal or something. So, anyway, I called the non-emergency police number, & they sent a patrol car.
After I called & while we were waiting on the police to show up, the guy walked back to the boxes, pulled out a red hoodie & put it on, & then walked back to the stop sign. He waited there another a few minutes & then took off walking down the street further into our subdivision. The "center" of our subdivision is heavily wooded. DH & I were worried that the guy was going to try to set up camp or something in the woods, & and it was freezing outside. DH, at this point, did go outside & tried to find him in the woods behind our house. But it was like he had disappeared when he went around the curve in the street.
When I first called the police, I had given them a description of what the guy was wearing, so I called back to give them an updated description. LOL! "Now, he's wearing a red hoodie! And he's not standing at the stop sign any longer!"
Anyway, the police got there & looked through the boxes before putting them in their car & then drove through the neighborhood looking for the guy. As they drove back by our house, they stopped & told DH it looked like the guy had been dumped there, but they couldn't find him. They then went to one of the houses across the street from us & talked to the older lady who lives there & gave her the boxes. Apparently, the guy was a former boyfriend of the lady's teenaged granddaughter. And the police were familiar w/ him & his contacts.
