I hope things are different in your area, but around where I live, nothing would be done about it. We had a guy come up to our house and defecate in front of me while I was calling 911 for the police. When he dropped his pants I thought it might be a sex offender and I was SCARED. I got his license plate number, description, etc...The police laughed it off...seriously, they actually thought it was funny.
We have police friends so we were able to get the guy picked up. He told a bunch of lies about being sick to his stomach and the DA declined to press charges (for indecent exposure). I didn't want the guy sent to prison, but maybe a fine and apology?!
Your case is worse than mine, so maybe they will do something. If you have law enforcement friends, they can help you.
Oh my gosh! not worse by far, we weren't there, it's a weekend place on the lake, he only took a few bottles of liquor, one was a $5 bottle of Tequilla with a worm in it we brought back from a cruise about 20 years ago, probably sent him to the hospital.

Besides breaking the window to get in, he's actually being kind of curteous. He shuts the cupboards and the fridge and the door behind him, and the first time, he cut himself pretty bad from the huge drops of blood we found outside, but inside, there was a whole bowl of blood in the sink, eeeewww, but not a paper towel or a drop anywhere. We tracked the blood to the inside of his parents house and that's how we were pretty sure it was him, then a neighbor who lives there year round saw him with his girlfriend at our door the 2nd time.
I'm extremely disappointed in the parents. I know that he's an adult, in his
late 20's, but they know it was him, but don't know that we know, so they haven't come clean. We were sure that we'd hear from them, and they'd get their son to or they'd offer to at least help fix the window. We've taken their grandsons who are close to the same age as our son, out to eat with us, fishing, tubing, they've spent the night, etc. so now I'm pretty sad, feel like selling the place.
If an investigator doesn't follow through, I hate that we'll have to call them ourselves.
Thanks so much everyone, and I'm sorry that happened to you Debbie. I'll let you all know what happens.
