On May 21, 2014, 10-year-old Sierra Guyton was on the playground at Clarke Street Elementary School in Milwaukee, Wisconsin, creating a dance routine with her older sister when gunfire broke out. The shots came during a dispute between two men over stolen baby clothes; Sierra was struck in the head by a stray bullet and later died after being taken off life support in July.

The shootout involved Sylvester Lewis, 19, and Jamey Jackson. Police say Lewis was confronted by a friend of Jackson’s, and Lewis reported that Jackson fired the first shot. Lewis then returned fire; investigators say a total of 16 shots were fired and as many as 50 children were on the playground. Lewis was charged with first-degree reckless homicide in Sierra’s death, first-degree recklessly endangering safety for her sister, and being a felon in possession of a firearm. Jackson was charged with being a felon in possession of a firearm.

Does anyone have more information about the scene that evening or knew Sierra and her family?
