ORLANDO, Fla. (AP) - A New Hampshire family who witnessed the death of a SeaWorld trainer by a killer whale is suing the Orlando theme park.

Suzanne and Todd Connell filed the lawsuit Tuesday, a day after the federal job safety agency fined SeaWorld Orlando $75,000 for three violations uncovered during an investigation into trainer Dawn Brancheau's death. Brancheau died in February when a killer whale known as Tilikium dragged her into a pool.

The lawsuit, which is seeking more than $15,000 in damages, claims the Connell's 10-year-old son suffered emotional distress from witnessing Brancheau's death.

A SeaWorld spokesman didn't immediately return a phone call.
