I'm going to tell my friends homophobic family that he's gay

My sister caught this fucker on her Alexa surveillance stealing a locked box filled with items. I'm talking jewelry, money, and other valuables. Some of which she was going to pass on to her son when he's older.

Later on, I confronted him, showed him the footage, and told him to surrender the items. He said he already sold the items and spent the money. I referred him to the names of banks that would give large loans to people with bad credit. He said he would do it with the understanding that no one turn him into the police.

Well he fled town. His number doesn't work anymore. His wife, his friends, and parents are worried about him. My brother and I are the only ones who know his secret and even have pictures on my brothers camera of him at the club kissing other men behind his wife's back. My brothers camera is high quality. Taking pictures is a hobby of his and he has kept every picture he's taken in his entire life even if it's mundane pictures of the sky. My sister filed a police report. She's probably never going to see the money or items she wanted to give my nephew ever again. The police go way too easy on people around here. If he gets caught, all he'll get is a slap on the wrist and be back on the streets again.

So we're just going to go on ahead and tell his ultra conservative anti gay family and wife he's gay. We're going to show them the pictures my brother has and the texts he sent confessing to us. They once said they'll disown him if he's gay. They already disowned a few gay people. If he ever comes back to town, he's fucked. IIN?
