A new book, Kardashian Dynasty: The Controversial Rise of Americas Royal Family from Gallery Books claims that Caitlyn Jenner changed into a female just to avoid being charged for involuntarily killing a woman in a traffic accident in February.

We previously reported that Bruce Jenner killed 69-year-old Kim Howe along the Pacific Coast Highway in Malibu in 2015. But the book says just two months later, the star announced his change from male to female to avoid manslaughter charges for taking Howe's life.

It was alleged in the book, which is from author Ian Halperin, that Bruce was 'driving at an unsafe speed' in Malibu at the time of the wreck. That means he could have faced some heavy charges.

"Before Bruce got into the accident, he gave the world hints about his true sexuality," Halperin quotes a friend as saying.

"After the accident, he went full steam ahead. I truly believe he was trying to misdirect the negative publicity he received after the car crash….it was clear he was worried about being charged."

The author quotes a friend of Jenner’s who insisted that the star 'misdirecting the serious offense by promoting his transition.' And when the June issue of Vanity Fair - which was put together in March - came out, Jenner had captured the attention of the world.

The L.A. District Attorney announced in September they would not file charges. In December Jenner settled a lawsuit filed against her by one of the drivers involved in the fatal crash.
