So i saw this thread when i searched google for my name and realized it has been almost ten years since this incident. I made an account on behalf of my girlfriend and she used it in hopes that some one would have an idea how to find her guinea pigs. it was a long shot and i searched that night for her but came up empty handed. it was cold and i think it snowed that night so it was a terrible situation and the people from this forum were very nice.
If your looking for answers why it happened, as an outsider looking in its pretty clear her entire family is dysfunctional and care very little for animal life, they buy animals thinking it will make them happy then lose interest because it requires real work and tons of money. Sorry you had to read about such a terrible incident and again thank you for everyone who tried to comfort my GF and help her out.
