Today at 11:15 a.m., someone opened fire inside the Mall in Columbia, in Columbia, Maryland, leaving three people dead including the person believed to be the shooter.

One of the three bodies was found beside a gun and ammunition, which is what has lead the Howard County Police Department to assume that person was the shooter. They have not yet said if the shooter took his own life or was shot by someone else, or if the two victims were targeted.

Already this week, one person was killed on the campus of South Carolina State University and another at Purdue University. Shots were reportedly fired at the University of Oklahoma on Wednesday, and earlier in the week a BART officer in San Francisco accidentally shot one of his colleagues dead.
