‘It’s all performative’: why are shooters leaving messages on shell casings?

The use of markings on ammunition is a new trend of shooters trying to ensure their messages are disseminated publicly, experts say

In the past month, the US has had to reckon with three deadly, high-profile shootings, and in each one, investigators have dealt with a seldom-seen piece of evidence in shooting cases, high-profile and otherwise: messages the shooter left on shell casings and firearm magazines.

The suspect in the 27 August shooting at Annunciation Catholic school in Minneapolis allegedly left several firearm magazines with messages like suck on this" written in white marker. Tyler Robinson, the man who's accused of killing Charlie Kirk, allegedly engraved his bullet casings with Hey fascist! Catch!" and Bella ciao." Authorities say the man who's suspected of opening fire at an US Immigration and Customs Enforcement (Ice) facility in Texas this week wrote Anti-Ice" on his bullet casings.
