Linda Boreman, who starred as Linda Lovelace in the 1972 pornographic film "Deep Throat" and later became an anti-porn advocate, died April 22 in Denver from injuries she suffered in a car crash. She was 53.

After the April 3 accident, Ms. Boreman was taken to Denver Health Medical Center with massive trauma and internal injuries, hospital spokeswoman Sara Spaulding said. She was taken off life support yesterday, Spaulding said.

Ms. Boreman's ex-husband, Larry Marchiano, said he and their two adult children were at the hospital when she died. "Everyone might know her as something else, but we knew her as Mom and as Linda," Marchiano said. "We divorced five years ago, but she was still my best friend."

The family moved to Colorado in 1990, and the couple divorced in 1996 after 22 years of marriage.

Ms. Boreman said her first husband, Chuck Traynor, forced her into pornography at gunpoint. They divorced in 1973. Their relationship disintegrated into a life of violence, rape, prostitution and pornography, according to her 1980 autobiography, "Ordeal."

Ms. Boreman said that she was never paid for "Deep Throat" and that her husband was paid only $1,250, though the film grossed a reported $600 million.

After leaving the industry, she traveled the lecture circuit on a crusade against pornography

"I look in the mirror and I look the happiest I've ever looked in my entire life," she said in 1997. "I'm not ashamed of my past or sad about it. And what people might think of me, well, that's not real. I look in the mirror and I know that I've survived."
