They've come to get down!

Yesterday in Portland's Monument Square was any other day. People busily went about their day, then the boom of MJ echoed through downtown. A group of 40 dancing zombies got down!

Event coordinator Kristen Sutton said it's been her lifelong dream to dance in public to Michael Jackson. Sutton is the general manager and teacher at a Westbrook dance studio. She says the zombie mob was planned well in advance.

A Facebook page was set up complete with instructional dance video. Zombie participants also were able to perfect their moves in two rehearsals prior to the big gig.

Sutton says she'll do another zombie flash mob next October, however probably not in Monument Square.
