If people don't stop fucking with my car there will be blood

I was thinking how it sounded like the stuff my sister had happening for 6 monthes in Madison, a few years back. It cumulated with them stealing a lens cover. She had to purchase the whole assemby for like $500. I see your in the same town. I’ll bet it’s some teen within a short distance from your apartment.
The most likely siphone point would be to put a hole in the rubber hose running from the cap to the tank opening. It’s like a radiator hose, and only has gas in it if you can see the gas is up to the cap, or durihng filling.
