Replacing stolen business inventory/trailer

My fathers business trailer was stolen from in front of their house. Inside was their entire business; stock, displays, tools, and all. Without this their entire livelihood is in jeopardy. My dad is recovering from back surgery he underwent on Dec 4th and my mom is medically retired. Both my parents are in very poor health and depend on their business to survive. So please, any help will be appreciated. Not sure what they’re gonna do without it. Thank you!
