Killer whale responsible for trainer's February 2010 death returns to SeaWorld shows on Wednesday

SeaWorld Orlando plans to put the killer whale Tilikum back into public performances beginning today, for the first time since the 6-ton whale killed a trainer at the marine park more than one year ago.

SeaWorld Parks & Entertainment President Jim Atchison signed off on the decision this week, and Tilikum is expected to appear in an 11:30 a.m. performance of "Believe," the company's main killer-whale show.
