They may not have been a real family, but Bill Cosby is devastated over the loss of his on-screen son, Malcolm-Jamal Warner, from The Cosby Show. The actor died in a drowning incident while swimming in Costa Rica on a family vacation on Sunday. He was just 54. Local authorities believe he stepped into the ocean and got swept away in a strong current - which also nearly took the life of a 35-year-old man who was rushed to the hospital in critical condition. So sad.
