Joan Rivers in medically induced coma

NEW YORK (NEWSCHANNEL 3) - Comedian Joan Rivers is hospitalized Friday morning.

Sources close to the 81-year-old's family say the legendary entertainer is in a medically induced coma at a New York hospital.

She allegedly went in for what was supposed to a routine endoscopy and the procedure was underway when she stopped breathing.

That's when she went into cardiac arrest.

Her daughter Melissa Rivers says the outpouring of support for her mother has been overwhelming.
