Take the report and lose it during the violence... multiple times.
No worries. She will find her car at one of the stores being looted filled with goodies. Dude probably gonna be wearing her mother’s coat, too.
"Who is this again? I'm sorry. There is a lot going on right now. I'll take a message. Don't call us. We'll call you."
next call...
"... You say your car was a Vega? I didn't know there were any of those left around. Prolly a classic by now. We don't have any reports for a stolen Vega."
Take the report. When the insurance company calls, tell them you can’t find it. Then nine months later, make sure it winds up stuck on her front doorstep with mud, boot tracks, and dirt all over it.
What? I can’t imagine how that happened lady...
