Say 2 - 3k for the guns; a similar amount for ammo. I’m assuming he didn’t haggle or price shop too hard. Maybe he ran off with his tuition money.

Several of us have figured most of the cost and the LEOs have discovered the supply routes, the vendors already. He didn't buy the weapons from the trunk of a gun runner's car for which he'd have to pay cash which he'd never have. His tuition money? Either his parents covered it or he had a student loan (which all of us covered) so that money went to the university and not to him directly. But a graduate student with a credit card or two could have easily run up a bill of $5 or 10k without notice....and with no intentions to repay it.

The real kicker to the taxpayers and parents is yet to come; his defense, court costs, shrinks will cost a fortune all for a punk kid who most likely wanted to prove that evil prevails after all.
