What kind of legal consequences might our neighbor's face?

They recently installed a fire place. Well, apparently they dumped still warm ashes out in the yard and their yard caught on fire.. They weren’t home so Rick called 911.
Can a person be ticketed for Being Super Stupid?

It was a weird day. Not 10 minutes earlier we had watched this semi catch on fire in the Walmart parking lot! I was on the phone with my daughter in law, who has been really sick. I was sincerely commiserating with her, telling her how much I cared and was there anything I could do then I saw the truck and I hung up on her to take pictures!
I sent her the picture first, along with an apology. And I called her when I got home. And then the neighbor’s yard caught on fire.
