Anyway, the asking price is too cheap for a hypothetical laser of this power to be anything other than IR.
EDIT: hakzaw1, The correct abbreviation of microwatts is μW (uW is also acceptable). If you typed mw, people would assume you meant milliwatts. Also, 1W = 1000mW = 1000000 μW, so 5000 μW = 5mW = 0.005W
Nobody. He's a spammer. Spammers don't have IRL friends or family. If anything he would be found after people couldn't stand the stench of his rotting corpse anymore and called the cops. But even then it wouldn't be because anyone cares about him (nobody cares about spammers) but because the smell of his corpse was offending the nostrils of his neighbors.
