They are blaming their own daughter and her boyfriend for the death of Keyontae Holzendorf. Keyontae was found dead inside a west Houston motel on Tuesday night. His mother Kayla Holzendorf and her boyfriend, Dominique Lewis, called to report that the boy had drowned in the bathtub while they were asleep. Kayla’s mother, Sheryl Holzendorf, agrees that her daughter’s story doesn’t add up. “You could not find a sweeter, more lovable, little boy,” Timothy said.
