Sometimes crimes go un-solved by the police. Sometimes, for example, a murderer is never found and the family's longing for justice is never satisfied. The trail of evidence may be meager to start with, and then it grows cold over the years.
J. Warner Wallace was a detective in Los Angeles. He took a closer look at old evidence and old statements by people who may not even be alive anymore.
Sometimes, though, he was able to interview the same people who gave testimony to investigators originally. Time may have dulled their memory, but he looked for more than memories.
A witness or suspect would write an account of his observations or activities. Using a technique called Forensic Statement Analysis, Wallace would look for signs of deception to give him clues regarding the truth or falsehood of the testimony.
