J. Warner Wallace is a cold-case homicide detective, popular national speaker and best-selling author. He continues to consult on cold-case investigations while serving as an adjunct professor of apologetics at Biola University and as a faculty member at Summit Ministries. J. Warner was a conscientious and vocal atheist until the age of thirty-five, when he took a serious and expansive look at the evidence for the Christian Worldview and determined that Christianity was demonstrably true. After becoming a Christ follower in 1996, Jim continued to take an evidential approach to truth as he examined the Christian worldview.

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.   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.
