DNA sketch leads to suspect confession in Texas slaying

After her oldest daughter was killed in May 2016, Michelle McDaniel and the rest of her family isolated themselves in their small Texas town out of fear that the unknown killer could be standing in line with them at the grocery store or passing them on the street. Then early last month, Brown County sheriff's investigators sent McDaniel a sketch of the man they suspected in her daughter's death, despite having no witnesses. The sketch was created using DNA found at the crime scene; a private lab used the sample to predict the shape of the killer's face, his skin tone, eye color and hair color.
