HOUSTON, TX (KTRK) -- The Walker County Sheriff's Office released video Thursday they say shows a man they want to speak with in connection with the murder of Caesar Coronado and the disappearance of his daughter, 14-year-old Adriana Coronado.

The first scene is from near Enterprise Row and I-45 in Conroe. It shows a Ford F-150 crew cab driving through what appears to be a parking lot. A fire starts, and a man is seen running away.

As desperation grows in the search for Adriana Coronado, her friends recall happier times.

The video then shows a tighter shot of the man running away. Investigators say he was possibly picked up by a dark-colored SUV.

Even though you can't see the person's face, investigators are hopeful people can identify him by his posture, his gait and his clothing.

Sheriff Clint McRae of Walker County said, "We at this point in time don't have any reason to believe that she's not alive."
