On April 19, 1995, a truck bomb expoded at the Alfred P. Murrah Federal Building in Oklahoma City, killing at least 168 people and injuring nearly 700 others. There were 19 children among the victims. Standing now on the grounds of the Murrah Building is the Oklahoma City National Memorial. The memorial contains 168 bronze and stone chairs, honoring each of the victims lost. Here’s a look at some images of the memorial park and museum, as we remember those lost on April 19, 1995.
