Daniel Melbourne Weiner, 30, was one of six employees killed in a mass shooting at Windy City Core Supply, an auto parts warehouse on Chicago’s South Side, on August 27, 2003. Weiner worked as a manager at the warehouse and is remembered by his family as a son, brother, uncle, and friend.

The shooter was identified as Salvador Tapia, a 36-year-old former employee who had been fired in March 2003 for repeated tardiness and absenteeism. Tapia returned to the workplace armed with a Walther PP .380-caliber semiautomatic pistol, tied up one employee, Eduardo Sanchez, and then shot employees as they arrived. Tapia engaged officers in a shootout and was killed by police after refusing to drop his weapon. The firearm was likely obtained illegally or stolen; its sale was recorded in 1966 and its last legal registration was in 1983.

Those who knew Daniel or worked at Windy City Core Supply are asked to share any memories or information that could add context to his life and the events that day.
