"I'm desperate," she said. "I need to find my little girl. It's been too many days and I'm dying alive."
The Katy teen was last seen Saturday. Investigators say her father, Ceasar Coronado, was found murdered and burned in a rural part of Walker County. A pickup truck they believe is connected to his murder was found in Conroe.
Investigators believe Adriana Coronado witnessed her father's murder and is in "grave danger."
Cavazos is in Mexico recovering from surgery. She says one of the last conversations she had with her daughter and husband of 20 years was about a sleepover she was planning to have at their apartment.
She says her husband was just a carpenter who wasn't involved with any dangerous dealings. She made a frantic plea to the people who have her daughter.
"We never have enemies. And I ask myself why do this to my husband. But if my husband has enemies, I didn't know anything. But I assure you guys that my daughter is innocent. Please do not hurt my daughter," she said. "Please be merciful to my daughter. And please return my daughter alive."
She says she knows people all over Houston are praying for her family and for Adriana's safe return.
"Thank you for all the support you're giving me, and your prayers," Cavazos said. "And please do not get tired of praying. She's the only reason for me to be alive."
