The former mistress of Chris Watts reportedly applied for a name change this month, shortly after Netflix released a documentary focusing on events leading up to his arrest for the murders of his wife and two young daughters. The Daily Mail reported that Nichol Kessinger, 32, applied for the change in Jefferson County, Colo. She was featured briefly on "American Murder: The Family Next Door," where she is seen in recordings telling police that she and Watts had an affair.
