VIDEO: Martha Von Bulow Dies After Decades In Coma

Von Bulow was found lying in a bathroom in her mansion in Newport, Rhode Island, in 1980 and never regained consciousness.

U.S. heiress Martha "Sunny" von Bulow died on Saturday at a Manhattan nursing home after spending nearly 28 years in a coma, media reported.

Von Bulow was either 76 or 77. She was found lying in a bathroom in her mansion in Newport, Rhode Island, in 1980 and never regained consciousness.

She was married to an Austrian prince and then later to a Danish-born lawyer, Claus von Bulow, who was convicted and later acquitted of twice trying to kill her with insulin injections. He now lives in London.

The story was recounted in a 1990 movie, "Reversal of Fortune," starring Glenn Close and Jeremy Irons, based on a book by Alan Dershowitz, a law professor who defended Claus von Bulow.
