San Antonio Express-News military reporter Sig Christenson highlights the Day 2 keynote address by Dr. Craig Bryan of Ohio State University as part of his coverage of the San Antonio Combat PTSD Conference. Dr. Bryan's presentation focused on preventing suicide by firearm as the "third rail" of suicide prevention. He explained that the right message from the right person could go a long way in encouraging secure firearm storage, which in turn could go a long way in preventing death by suicide, especially among service members and veterans.
