Police arrested 22-year-old 43-year-old Johnny Shane Barker and the 16-year-old brother of Garcia-Boettler, who police say is the suspected shooter. Their mother, Crystal Rachelle Boettler, 40, has also been charged with accessory after the fact.” According to court records, “on April 14, Garcia-Boettler drove his brother to meet the two victims because he believed his brother was going to purchase a gun from Moreland. The sale was arranged through Craigslist and the two parties agreed to meet in a nearby grocery store parking lot. Garcia-Boettler told police that Moreland got out of a sedan and into the back seat of his van. He claims that he heard a gun “rack” and told police he witnessed his brother open fire killing the two men.”
