You’d think that a news story from a respectable journalistic outlet such as LA Eater would have provided more details.
You know, what tools did he use to tamper with the car (a burger-flipping spatula?), what caliber was his firearm, what brand of sugar and how much was used, did he pour it from a box, a bag, or a bunch of tiny packets that he took from the restaurant, what was the make, model, year, and color of the boss’s car, was it actually disabled or not, etc.
Inquiring minds want to know, and all that...
Eater just repeats what it got from the Glendale PD public information officer. No journalistic investigation needed.

Now you've stressed this 'writer'. Better make sure you have a locking gas cap.
