I think we might have been cased for a burglary. A 40ish black woman came to the door saying she was looking for a lost dog. When asked what the dog looked like, what it’s name was, or where she lost it, she could not answer any questions at all. Never looked us in the eye, just craned her neck looking around the house and past us. Very uncomfortable situation. She left quickly and as she walked down the steps and across the street, a big black SUV with 2 men in it pulled up to get her. When they noticed us watching them, they screeched off quickly down the street. Didn’t get a license number or great description because they rounded the corner and took off so fast.

She notes that the police think they were likely just wanting to see if anyone was home and checking out what sort of lucrative easy pickings might be inside to be burgled. Hopefully they’ve been scared off and won’t be back soon, but be aware of this now-common sort of ploy.
