John Travolta and his wife, Kelly Preston, are in mourning for their son, Jett, who was found dead in a bathtub in the Bahamas after enduring a seizure, according to Michael Ossi, the family lawyer. The Travoltas said Jett had for many years been suffering from Kawasaki Syndrome, a rare condition characterized by high fever, skin rashes, swelling of the lymph nodes, and heart attacks caused by inflammation of blood vessels in the coronary arteries. In 2002, Preston said her son had become “very, very sick with high fever and swollen glands and peeling fingers and rash all over his body” when he was 3 years old. She attributes the condition to exposure to carpet-cleaning chemicals and as a result she became a crusader for safe household chemicals. Travolta said recently he and his wife were hoping to have another baby. They married in 1991 and have a daughter, Ella, 8.
