A Call for Help

I'm locked in what seems to be a lab, I was able to sneak into this place where the computers are, and thank god there is an internet connection.

I'll give it to you short and sweet, since I probably don't have much time. Now, I don't know if the other guys got here the same way I did, but I was one day checking my mail and I found this envelope with a peculiar wax seal, I don't remember what the letter said, hell, I don't even remember if there WAS any letter, but after I was finished with it, I just started running, nothing seemed to stop me and I just ran and ran and ran. The next thing I knew I was waking up inside of a cell along with other people I had never seen in my life.

The people here are grouped together, for what I can see, by general physical characteristics, there is a group of short, moustached men, another that is full of short twins, and another with young, black-haired children. I'm in the one that is full of young, blonde, blue eyed guys. I'm not sure if there are other groups, but I have a feeling that there are.

I've been here for a long  time now, and every day some guys in hazmat suits come in and poke us around with needles, and I can assure you that's the reason I've lost the ability of vocal speech, everything I try to say comes out in gibberish.

There's a rumor going around among those that can still speak and other groups that don't seem to lose that ability. That rumor goes that once we have certain physical characteristics we get sent off to to who knows where and fight to the death for some sicko's entretainment, usually in the same groups as we are locked together with, but some of the people have left ALONE, and never come back so I can't be sure of that part, but what I do know is that I need to get the hell out of here before I'm killed for someone's amusement, please, somebody, anybody, help me. I don't know where I am, the only clue is the sign I saw on a door the other day, if I'm not wrong it said something like "HAL Laboratories".
