He hunted for his daughter’s killer for 40 years. Then he got a phone call

Tim Miller's teen daughter disappeared in 1984, tied to a series of deaths in the Texas killing fields'. After decades, he received a tip that unlocked everything

Tim Miller is good at finding missing people - or rather, their bodies. Four years ago, a stranger called him and left a rambling message claiming that he had important information about an unsolved murder case.

Miller, who lives in Texas and runs a non-profit search-and-recovery organization called EquuSearch, did not treat the message as a high priority. The caller sounded as if he might have been drunk or on drugs. Although tips are vital to EquuSearch's work, the tip line brings a certain number of hoaxes, cranks and innuendo. Some of the people who leave messages, Miller told me, probably ought to get their medication checked".
