Los Angeles (CNN) The police investigation into a deadly four-car accident involving Caitlyn Jenner is finished and the results could lead to a misdemeanor manslaughter charge against the reality television star, a Los Angeles County Sheriff's detective said Thursday.

"Jenner's case is going to go to the district attorney next week to see if it is worthy of a misdemeanor violation for involuntary manslaughter," Det. Richard Curry said.

Jenner was driving a black Cadillac SUV on February 7 that was the third vehicle involved in a multiple rear-end collision on Pacific Coast Highway in Malibu, police have said. Kimberly Howe, 69, was driving her Lexus when Jenner's SUV hit her car from behind, sending it into oncoming traffic where it was hit by another SUV.

She died at the scene, police said.

"We did determine in the investigation that Jenner was going at an unsafe speed for the prevailing conditions, even though he was traveling under the posted speed limit," Curry said.

But Jenner didn't commit gross negligence, Curry said.

The 1976 Olympic decathlon champion released a statement after the accident: "My heartfelt and deepest sympathies go out to the family and loved ones, and to all of those who were involved or injured in this terrible accident. "It is a devastating tragedy, and I cannot pretend to imagine what this family is going through at this time. I am praying for them."

Jenner's publicist, Alan Neirob, said the "I Am Cait" star had no comment on the DA getting the case.

CNN affiliate KABC reported the Howe family also declined to release a statement.

A conviction for misdemeanor involuntary manslaughter can bring a sentence of up to one year in prison, Loyola law professor Stanley Goldman said.
