The five occupants of the Hummer into which Kim Howe, who was killed in February after Caitlyn Jenner crashed into her car, slammed are suing her estate for $18.5 million, TMZ reports.

The creditors claim Howe was negligent, alleging that she caused the collision. TMZ also reports that they plan to sue Jenner as well.

Last week, the Los Angeles Sheriff’s Department recommended that Jenner be charged with vehicular manslaughter.
