A Chicago man faces a federal weapons charge after he essentially handed investigators their entire case by posting a series of Snapchat videos of himself handling firearms, roaming rival gang territory while armed, and even firing a handgun into the air while identifying himself as a gang member, according to court records.
The case against Alexander Martinez-Quiroz reads less like a high-stakes federal investigation and more like an unwitting confession that investigators stumbled across online.
An FBI agent who wrote the complaint supporting the charges said investigators obtained a search warrant for Martinez-Quiroz’s Snapchat account in March and found a trove of videos he had saved or sent to others.
In a clip dated December 18, 2025, Martinez-Quiroz, purportedly a Two Six gang member, is allegedly shown driving a Ford F-150 along a stretch of 46th Street known to be Latin Saint gang territory, holding a firearm.
“I don’t give a f***, I’ll die today, I don’t give a f***. Somebody’s dying today, though. I promise you that. Rest in peace my n****, Lechuga. Saint killer. If I don’t drop a Saint, I’ll drop a donut for real, I promise you that,” he allegedly said in the Snap.
The agent’s filing said a “donut” is a street term used to refer to members of the Satan Disciples, another rival gang. The agent alleges Martinez-Quiroz was seeking to shoot a Latin Saints member or a Satan Disciple in retaliation for the killing of someone he called “Lechuga.”
Chicago police told federal investigators that a man named Lewis Lechuga was shot and killed on January 30, 2023, in the parking lot of a Taco Bell at 4614 South Damen Street, and that Lechuga was a suspected Two Six gang member, according to the complaint.
That same Taco Bell parking lot appears in another Snap the feds allegedly found in Martinez-Quiroz’s account. That video allegedly showed him getting out of a vehicle in the parking lot and holding a firearm to his chest. He again invoked Lechuga’s name before saying, “47th street. I’m gonna pack you n***** up,” according to the complaint.
About ten minutes after that, Martinez-Quiroz allegedly made a third video walking down a street in Latin Saints territory, holding a firearm in one hand and recording with the other, asking aloud, “Where the Saints today, though?”
Roughly half an hour later, things escalated further in a fourth video as Martinez-Quiroz allegedly recorded himself inside a vehicle.
“Hold on, this s*** is gonna be funny,” he said, getting out of the vehicle and standing in front of a brick building. “What am I? Yeah, I’m a gangster Two-Six. What’s up?”
He then raised his left hand and fired a handgun three times into the air, the complaint states.
“Exactly. Y’all n****s ain’t on s***.”
Investigators found an earlier clip from December 14 that allegedly showed a table covered in firearms, including a rifle, a Glock-style handgun with a drum magazine, a handgun with an extended magazine, and various loose ammunition, with someone handling the weapons and saying, “Gotta reload these b****es, f***.”
The rifle’s serial number is partially visible in the video, and ATF records identified it as a weapon stolen from a shipment traveling from a Michigan manufacturer to a company in Iowa, the complaint said.
Investigators linked the earlier footage to Martinez-Quiroz’s residence through geolocation data embedded in the video.
On Thursday, federal agents executed search warrants at Martinez-Quiroz’s home, on his vehicle, and on his person.
When they searched his home, they say they found the stolen GL-15 rifle, loaded, along with a loaded Glock Model 19 with a drum-style magazine, multiple rounds of ammunition, a Springfield XD firearm case containing a loaded magazine, and an extended magazine, all items similar to those seen in the December 14 video.
Martinez-Quiroz is charged with one count of being a felon in possession of a firearm.
