J. Warner Wallace

Los Angeles County homicide detective and author of Person of Interest Investigator's Guide: Why Jesus Still Matters in a World that Rejects the Bible

"I'm not a Christian because it ‘works’ for me. I’m a Christian because it’s true." A retired cold case homicide detective, J. Warner Wallace was a vocal atheist for many years - until he applied his investigative training to the Gospels and determined that Christianity is demonstrably true. You may recognize him from NBC's Dateline, where he’s appeared more than any other detective in the country.

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 Unniversity) 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.

J. Warner’s professional investigative work has received national recognition; his cases have been featured more than any other detective on NBC’s Dateline, and his work has also appeared on CourtTV and Fox News. He also appears on television as an investigative consultant (most recently on truTV) and had a role in God’s Not Dead 2, making the case for the historicity of Jesus. J. Warner was awarded the Police and Fire Medal of Valor “Sustained Superiority” Award for his continuing work on cold-case homicides, and the CopsWest Award after solving a 1979 murder. Relying on over two decades of investigative experience, J. Warner provides his readers and audiences with the tools they will need to investigate the claims of Christianity and make a convincing case for the truth of the Christian worldview.

J. Warner is married to Susie (the love of his life since 1979) and has four children. He lives in Southern California where he enjoys running on the beach and the trails and walking his trusty Corgi, Bailey.

Jim wasn’t raised as a Christian. In fact, he was a conscientious and vocal atheist until he was 35 years old and always considered himself to be an “evidentialist”. His experience in law enforcement only served to strengthen his conviction that truth was tied directly to evidence. But J. Warner eventually took a serious and expansive look at the evidence for the Christian Worldview and determined that Christianity was true. J. Warner eventually served as a Youth Pastor for several years and planted a church in 2006. Along the way, he created and built the ColdCaseChristianity.com website as a place to post and talk about what he discovered related to the evidence supporting Christianity.
