Working With A Drunk Felon

In Texas: My coworker, 21M, who I will call N, has been arrested multiple times and charged with: reckless driving, 2 seperate charges of PCS PG 2 >=4g<400g, tamper/fabricate physical evidence with intent to impair, theft under $100, agg assault with a deadly weapon, and POM <2oz. All of the arrests happened when he was 20 years old.

I’m not sure which he has been convicted for, but all of this was public information, found simply by googling his name.

This all started when he left a water bottle at work, which me and another coworker agreed smelled heavily of alcohol. We contacted the owner of our workplace, who agreed that there was alcohol in the bottle. The owner then had a talk with N, but did not take any action further than that. Later on, he left ANOTHER bottle which me and a coworker agreed had alcohol in it, but the owner did not smell any. After N found out we told the owners, he threatened my coworker with tampering with the brakes and tires on his car.

After these incidents, none of the other coworkers feel safe with N, as our workplace contains kitchen equipment such as knives and gas stoves. We have gone to the owners about this but they are not willing to fire him. They are aware of N’s arrests and the threats made against my coworker.

Since the owners will not do anything about this, I feel that I need to take actions into my own hands. Should I make a report about N’s actions to the police or the parole/probation office? What actions can I take to get N out of our workplace, so we can work in a safe environment?
