The brother of a 20-year-old South Florida man charged with threatening to re-enact the Virginia Tech massacre says he never intended to hurt anyone.

Vincent Wong says he brother, Calin Chi Wong, just had a stockpile of assault weapons and thousands of rounds of ammunition at his Homestead home for investment purposes. He says Wong traded the weapons like "Pokemon" cards.

Police say Calin Chi Wong had 13 firearms in all, including two sniper rifles, more than 5,000 rounds of ammunition, some that could pierce armor, and 100 rounds in a feeding clip with bullets meant to take down aircraft or military machines.

Police say he made the threat over the Internet after he felt he was ripped off in a gun deal.

Homestead is about 30 miles south of Miami.
