ORLANDO, Fla. – The killer whale that drowned a trainer last year at SeaWorld in Orlando is performing in shows for the first time since the death.
SeaWorld officials said Tilikum participated in the marine park's "Believe" show on Wednesday morning.
Tilikum drowned 40-year-old Dawn Brancheau on Feb. 24, 2010.
Trainers remained out of the pool Wednesday for the performance before a crowd that filled the 5,000-seat Shamu Stadium.
The park is working on plans to get trainers back in the water with the whales. The federal Occupational Safety and Health Administration last summer accused SeaWorld of recklessly putting trainers in danger. The company is fighting OSHA's citations and $75,000 fine.
Outside the park, about a dozen people protested against the park's keeping Tilikum and other whales in captivity.
The hottest stories ripped from the headlines, from crime to courts, legal and scandal.
