J. Warner Wallace is a Dateline featured cold-case homicide detective, popular national speaker, and best-selling author. He continues to consult on cold-case investigations while serving as a Senior Fellow at the Colson Center for Christian Worldview. He is also an adjunct professor of apologetics at Talbot School of Theology (Biola University) and Southern Evangelical Seminary, and a faculty member at Summit Ministries. J. Warner became a Christ-follower at the age of thirty-five after investigating the claims of the New Testament gospels using his skill set as a detective. He eventually earned a Master’s Degree in Theological Studies from Gateway Seminary.

J. Warner has appeared on television and radio, explaining the role that evidence plays in the Christian definition of “faith” and defending the historicity of Jesus, the reliability of the Bible and the truth of the Christian worldview. Jim also speaks at churches, retreats, and camps as he seeks to help people become confident Christian case makers. J. Warner’s book, Cold-Case Christianity, provides readers with ten principles of cold case investigations and utilizes these principles to examine the reliability of the gospel eyewitness accounts. In God’s Crime Scene, he investigates eight pieces of evidence in the universe to make the case for God’s existence. In Forensic Faith, J. Warner makes the case for a more reasonable, evidential Christian faith.
