NEW YORK (WPIX) -- The New York City medical examiner's office revealed Thursday a blunt impact to the head caused the death of actress Natasha Richardson. The 45-year-old suffered the head injury Monday after a skiing accident in Montreal. Richardson was taken off life support Wednesday afternoon, as she was surrounded by family and friends in her room at Lenox Hill Hospital in Manhattan.

In wake of her passing, Broadway theaters will dim their lights Thursday at 8 p.m. EDT for one minute in honor of the Tony-award winning actress.

A stunned entertainment community has begun to react to her tragic death.

Sam Mendes, who directed Richardson in her Tony award-winning role in "Cabaret" said in a statement "it defies belief that this gifted, brave, tenacious, wonderful woman is gone."


Lindsay Lohan, who co-starred with Richardson in "Parent Trap", told the Associated Press, "She was a wonderful woman and actress who treated me like her own. My heart goes out to her and her family."

Jane Fonda remembers meeting a young Natasha on the set of the 1977 film "Julia", where Fonda starred with Richardson's mom Vanessa Redgrave.

"She was a little girl, but already beautiful and graceful. It is hard to even imagine what it must be like for her family," she said.

Oprah Winfrey called her death "another reminder of how fleeting life can be and how precious. We need to value every moment."

More details are now surfacing surrounding the events on the day of her accident.

According to the AP, EMS director Yves Coderre, who sent paramedics to Mont Tremblant where the actress suffered her fall, told a Canadian newspaper the paramedics who responded were told they weren't needed, so they turned around. Corderre later sent a second ambulance after getting a 911 call from her hotel, but by then it was too late.

Funeral services for Richardson were underway Thursday. The Greenwich Village Funeral Home will reportedly hold a service for the actress, told PIX News Richardson's family has requested the serviced remain private.

Richardson's film credits include "Gothic," "Nell," "The Parent Trap" and "Maid in Manhattan". She won the 1998 Tony Award for playing Sally Bowles in "Cabaret."
