The Lake City Army Ammunition Plant was built in Independence, Missouri, during World War II, and has made nearly all of the rifle cartridges used by the U.S. military since it pulled out of Vietnam. In recent years, The New York Times reports, the plant, now operated by a private contractor with Army oversight, has produced billions of rounds of military-grade ammunition for the commercial market, making it one of the country’s biggest manufacturers of rounds for the AR-15. Today, its casings, marked with its “LC” signature, are found at crime scenes nationwide, including at the sites of some of the deadliest mass shootings in recent U.S. history.

The Times’s investigation found that the plant’s ammunition has been tied to at least a dozen mass shootings involving AR-15-style weapons, including at Marjory Stoneman Douglas High School in Parkland, Florida; an Aurora, Colorado, movie theater; the Tree of Life synagogue in Pittsburgh; a Tops Friendly Market in Buffalo, New York; and Robb Elementary School in Uvalde, Texas.

In Philadelphia neighborhoods where shootings are frequent, residents have long shouldered the hazardous and traumatic work of cleaning up blood from the scene of a crime — and oftentimes, loved ones of victims undertake the task while they grieve their loss.
