LOS ANGELES — The stepchildren of a woman killed in a car crash involving Bruce Jenner filed a wrongful-death lawsuit Friday against the Olympian, accusing him of being negligent.

William Howe and Dana Redmond, the stepchildren of Kim Howe, 69, say Jenner is responsible for causing her death and “damage to her effects,” according to the lawsuit filed in Los Angeles Superior Court. They said they have suffered “enormous damages and losses.”

Jenner “violated the rules of the road” and was “negligent, careless and reckless,” according to the lawsuit.

The lawsuit alleges Jenner violated the basic speed law, a California vehicle code section “designed to protect” their stepmother.

Her stepchildren say she was acting with “caution, attention and care and did not in any way contribute to, or cause” the crash.

Her children say they have lost love and affection as a result of her death. They incurred bills and have had to pay for damages, according to the lawsuit.

They are seeking unspecified damages.

Calls to the stepchildren’s attorney and Jenner’s attorney were not immediately returned.

Howe was killed Feb. 7 on Pacific Coast Highway in Malibu when her Lexus was rear-ended by Jenner’s Cadillac Escalade and went into oncoming traffic, where it was hit head-on by a Hummer.

Howe was driving behind a Toyota Prius, which came to a sudden stop. She was rear-ended by Jenner, who was towing a trailer with an off-road vehicle.

An initial account of the accident said Howe rear-ended the Prius, then Jenner rear-ended Howe’s vehicle, pushing it into oncoming traffic.

But attorney Robert Simon, who represents the Prius driver, said his client was hit by Jenner’s Escalade — not Howe’s Lexus as first described.

After the Lexus was pushed into oncoming traffic, where it was struck by the Hummer, Jenner’s SUV continued on and hit his client’s car, Simon said.
