The Keeping Up with the Kardashians star was involved in a pile-up on the Pacific Coast Highway which saw his car slam into Kim Howe, sending her Lexus into oncoming traffic, where it was hit by a hummer, causing the woman's death.
And now her adult stepchildren - who reportedly had "virtually no relationship" with Kim - are said to be gearing up to take legal action over the crash because there are no other surviving family members with a legal right to file a wrongful death lawsuit.
