Mrs Howe was driving a white Lexus, which Jenner's Cadillac Escalade rear-ended on a segment of the Pacific Coast Highway in Malibu, California, on February 7. Scroll down for video .

Crash: Mr Jenner is said to have 'rear-ended' her white Lexus, which was pushed into oncoming traffic . The car was pushed into oncoming traffic, and collided with a black Hummer, leaving the vehicle a crumpled wreck. According to TMZ, the two step-children are said to have 'lawyered up', because they are the only people who could launch a wrongful death suit. Mrs Howe's husband Robert died in 2003, and it is understood she has no other close living blood relatives. Attorneys have previously warned 'the sky's the limit' if it came to a court case, with juries able to award huge amounts. However, sources close to the investigation have said Mr Jenner - who was not hurt in the incident  -  is only insured up to $250,000, meaning he may have to pay out from his personal finances. It is believed he shares an $125million fortune with his ex-wife, Kris Jenner. No charges?: Sources close to the investigation believe Mr Jenner won't be prosecuted for manslaughter .

Police sources say he is unlikely to be prosecuted by the Sheriff because he wasn't drinking, speeding or texting at the time of the fatal crash. However, that still leaves the possibility of a wrongful death suit. Close friends of Mrs Howe have told the celebrity website she had 'virtually no relationship' with either of her late husband's children, neither of whom live in California. Sources went on to tell TMZ that one of the step-children had been asked to find pictures of the pair together, to prove their relationship - and therefore the amount its loss has cost them.

New York-born Mrs Howe, who was childless, was  'very socially active', according to one member of the exclusive community in Calabsas, where she lives alongside the likes of Jenner's Kardashian stepdaughters. Jim Pascucci, a realtor who lived in the neighborhood, and also sold the Howes their $2.5million house, told the New York Daily News she was 'sweet' and 'charitable'. According to the newspaper, she had put aside an amount of money to go towards animal charities -an sum which could be in the millions.
