This one is a doozy, and long, so skip to bottom for TL:DR.
Late last year, (then F-)SIL, "Meg", started dating "Stewie." We met him once, he seemed nice enough, quiet. She didn't bring him around a lot. We learned that very soon after, he had moved into her house with her. We thought it was a bit fast, but never said anything. We also learned at some point that Stewie had a DUI and couldn't drive. Well, great, we're not big fans, but they are a couple. We sent out STDs in early January and included Stewie.
In Mid-March, Meg went out of town for job training. She ended up flying home a day early, and when she arrived, Stewie was no longer answering his phone - no calls, no texts, nothing. FFIL drove her home from the airport, and when she walked into her home, all electronics were missing: computers, TVs, stereos, speakers, the works. Basically anything of pawnable status was gone. Her car had been driven and was slightly dented, and numerous addresses had been programmed into the GPS (including the pawn shop and home of a certain drug dealer - talk about dumb criminal).
It took a long time to sort out the fallout, and I still don't know that all items have been retrieved or compensated.
In any case, this all happened about two weeks before invites went out for our wedding, so we sent FSIL an invite, with the then ex-bf excluded. (By excluded, I simply mean it was addressed to her only). We had asked her about a week after it all happened if she had in fact broken up with him (moot point, I thought), but she confirmed, yes, they were over.
Last week, she posted a photo of him to FB; they were out to dinner. Today, it's 9-month anniversary flowers from him. I'm sorry; 9 months??
So apparently they are back together, and are acting as though they never weren't together. Needless to say, when our wedding rolled around in May, he was not invited. Just thought I'd share this fun tale!
TL:DR - SIL dated a guy. When she was out of town, he stole (and sold) everything electronic she owned. They "broke up," and our wedding happened. He was not invited. Turns out, they are back together and are now acting as though they've been together the whole time.
I feel no guilt.
Any other dumb criminal stories?
