On May 22, 2024, two brothers were killed in a workplace shooting at Delaware County Linen in Chester, Pennsylvania. Giguenson Peña-Peña, 26, and his brother Leovanny Peña-Peña, 29, both from Moca, Dominican Republic, were fatally shot after a coworker, 61-year-old Wilbert Rosado-Ruiz, returned to the facility armed following a verbal dispute with a female employee. Surveillance footage reportedly shows Rosado-Ruiz walking through the building and opening fire on coworkers; three other employees were also wounded, including the woman involved in the earlier argument.

Outside the building he tried to shoot that woman again but his gun either jammed or was out of ammunition, and he fled before being arrested by Trainer, Pennsylvania police officers. Rosado-Ruiz has been charged with first-degree murder, aggravated assault, and recklessly endangering another person; investigators say he had legally purchased the handgun in 2018 but did not have a license to carry it concealed.

Coworkers had reportedly raised concerns about his behavior, and a meeting about those concerns had been held the day before the shooting.
