Unsurprisingly, two of the three suspects have criminal records:
Officers are searching for 20-year-old Daniel Jermaine Anderson, 16-year-old Michael Mayberry and 17-year-old Anton Nelson. Anderson served a short sentence in the Oklahoma Department of Corrections for possession of a controlled substance in 2008-09. Muskogee police issued a warrant for Mayberry's arrest earlier in the week on an unrelated case.
Perhaps it's time to make the "gun free zone" a less target rich environment.
