A two-month joint investigation by federal and local law enforcement resulted in the arrest of 41 people and the recovery of 171 firearms and 64 machine gun conversion devices in the Chicago area, officials stated Tuesday.
According to the ATF and the Chicago Police Department, the individuals face various federal and state offenses.
Authorities linked several of the seized firearms to violent crimes, such as murder and aggravated assault, that took place in Chicago and other locations between 2017 and 2025.
What we know: The operation focused on those suspected of illegally possessing, using, or trafficking firearms and machine gun conversion devices, also known as “switches,” which may convert semi-automatic weapons into fully automatic ones.
Among those arrested was Alec Chisolm-Blockton, who was on parole for aggravated battery in connection with a shooting that killed a 14-year-old, according to authorities.
Eddie Arguelles, another suspect, allegedly opened fire at a crowded park with a firearm fitted with a conversion device that turns it into a machine gun.
Torrence Lindsey-Bynum, who had previously been convicted of threatening a mass shooting, was also detained with a pistol and a conversion device, according to the ATF.
What they’re saying: “Machine gun conversion devices are increasingly being used by criminals, putting both innocent civilians and law enforcement in danger,” said ATF Special Agent in Charge Christopher Amon. “This operation aggressively targeted offenders suspected of trafficking illegal machine gun conversion devices into our communities…”
“Combating gun violence is my office’s highest priority, and there is no doubt the recent proliferation of MCD’s is a threat to our progress,” said Cook County State’s Attorney Eileen O’Neill Burke. “A firearm equipped with one of these devices and an extended magazine can fire off 30 rounds in less than two seconds, terrorizing our neighborhoods and too often catching innocent bystanders in the crossfire…”
