That is an almost-stolen catalytic converter and the tool the would-be thieves had to leave behind when Edgar chased them off late last night:
Heard a clatter outside our house on the corner of 42nd and SW Brandon and found two young men taking liberties with my Lexus catalytic converter. Not my best moment but I ran out, swore at them and proceeded to kick the guy that was underneath my car and they took off in a sedan with Oregon plates. They threw their beverage at me on the way by.
A call to police ensued. SPD incident # is 21-261915.
