Ph.D. candidate Frank Wendt runs a test to detect pieces of DNA that are important for metabolizing drugs at the University of North Texas Center for Human Identification research and development lab on Monday, July 31, 2017, in Fort Worth, Texas. The university's case lab, which tests DNA for missing people and unidentified dead, has temporarily stopped accepting out-of-state samples after the National Institute of Justice opted not to offer millions of dollars in grants for DNA technology to identify missing people.
