From the Chronicle:
" The sheriff said the Trinity River Authority slowed down the outflow from the reservoir to lower the water levels in the river so search teams could locate the missing girl's body.
Don Steven McDougal, 42, will be charged with capital murder in connection with her death, the Polk County District Attorney said. He is already in jail on an unrelated aggravated assault charge. He has an extensive criminal history with multiple violent convictions.
Sheriff Byron Lyons said information from witnesses, cellphone data and social media sent in by citizens led them to the body off Highway 59."
