“go visit the bike with a Marine friend.”
And guess who goes to jail.
And that is why I say Attorney. You do not want to go the illegal way. If cops are not helping what recourse? You get an attorney.
You pay taxes and the cops will not help so you have to go another route.
Other than that he is screwed.
Honestly if your kid had an ebike he should have put it inside a garage or house to keep it safe from robbers.
