Cheesy Murder Mystery from 2005-2015

I'm looking for a book I read sometime in the past 10 maybe 15 years. It was a very cheesy murder mystery about some college friends we all had the same teacher and somehow they all wound up reuniting at the school. It's of those books that does everything to lead you to believe each character is the one that did it and then reveals the real killer on the last page. I think there was an ax or bloody ax on the cover but I'm not certain. I think the cover was white , brown, and orange. If anyone Can think of the title or has any ideas please let me know. Thank you.
