Hey guys I've got a little situation, well not technically me. My grandma lives by herself in a rather rural part of middle GA and has been having some issues with a man coming up on her porch and just hang out. She says she doesn't always hear him actually step up on the porch but every so often she'll hear him move on one of the chairs or something. She's called the cops a few times about it but they say they really can't do much. They've dusted for prints but nothing came back.
It doesn't happen more often than a couple times a month and the guy has never knocked on the door, broken or stolen anything but it's understandably scared her. She has a little .22 pistol that she's gone outside with after she's heard him (she's pretty brave) but she's never been able to see him. I've made a point to come stay with her every few weeks but I've never heard him myself, although my mom has before when she went down.
Any ideas of what to do besides try to catch him trespassing and show him my Glock?
