He was a public employee - of the TX prison system? He was stealing 1) from the TX taxpayers, who paid his salary (a fraud, whenever he was working his side job) & 2) he was stealing food (or the $ to pay for it) from the intended recipients, juvenile offenders in the TX juvenile prison system. Lock him up, throw away the spatula, & make him eat C-rats for whatever remains of his natural life. (& quite frankly, all those kids he stiffed in TX juvenile detention while on the job have bigger brothers, uncles, fathers. I don't think this offender's life is going to be worth a plug nickel on the inside.)
The other interesting question: The kids whose meals he was stealing - How were they fed? Did the prison system have to go out & pay for meals again, or did the inmates simply go hungry? Or even more interesting, did our enterprising felon then sell off the remaining meals for yet another tidy ill-gotten profit?
Another question: I would hope that whatever Mickey Mouse outfit - the TX board of prisons financial controls unit? Do they get periodic outside audits? Have the internal unit administrators been fired wholesale - of course - (or better still, consigned to the TX juvenile detention center in question - until they can satisfactorily explain how they missed $1 million plus in misapplied funds over the course of 8 years)? The outside auditing firm - if there is one - should also be fired forthwith, & levied a fine equal to the amount they were paid to audit the food budget @ the juvenile detention center in question.
Unless this is the Best little countinghouse in Texas - somebody was covering for the perp on the inside. Find him or her - or however many there were - & try & send them to keep our felon company. After all, misery loves ...
