One of the highest-ranking officers in the Chicago Police Department barred city cops from responding to calls for help from federal agents who reported being surrounded by a large crowd in Brighton Park on Saturday, according to CPD radio transmissions.
CPD Chief of Patrol Jon Hein ordered city officers to leave the area as tensions escalated following the shooting of a woman by Border Patrol agents, supervisors said in recorded radio traffic.
Around 10:30 a.m., a woman called 911 and reported that an Immigration and Customs Enforcement agent had shot her in the 3900 block of South Kedzie, according to CPD dispatch records. Chicago officers initially responded to the scene, where federal agents claimed the woman was armed and part of a caravan of vehicles attempting to obstruct ICE operations. She was transported to Mount Sinai Hospital with gunshot wounds to her legs, arm, and chest, according to preliminary information.
On Saturday night, the Department of Homeland Security identified the woman as Marimar Martinez, saying she “was armed with a semi-automatic weapon and has a history of doxxing federal agents. She took defensive fire from CBP agents and has been discharged from the hospital and is currently in the custody of the FBI.”
“The driver of another vehicle, Anthony Ian Santos Ruiz, involved in the ramming has been apprehended by law enforcement,” DHS said in a statement.
Protests erupted in the area shortly after the shooting.
“As our ICE law enforcement was responding to the shooting, a domestic terrorist followed them and rammed their vehicle in an attempt to run them off the road. This individual has also been arrested and is in HSI custody,” DHS added.
Video circulating on social media shows a separate incident in which an SUV repeatedly rammed an unmarked Border Patrol pickup truck as the vehicles traveled south on Kedzie Avenue near 36th Place. The truck’s emergency lights were activated as the black SUV struck its bumper multiple times. Both vehicles then sped south in the opposite lane of traffic.

After passing under a viaduct, the SUV forced the Border Patrol truck into a curb at 3700 South Kedzie, kicking up dust from road construction. Even after the crash, the SUV’s driver continued accelerating into the pickup as an agent emerged from the truck and appeared to aim a firearm at him.
A second federal vehicle arrived and rammed the SUV from behind as more agents jumped out. The SUV then suddenly accelerated forward, bouncing into the air several times before coming to rest in a construction zone.
At about 11:30 a.m., a CPD supervisor in the Deering (9th) District instructed dispatchers to “clear up” all of the city’s police units from the shooting investigation and turn the scene over to federal authorities.
“That’s per the chief,” the supervisor said.
“That’s per the chief of what? ICE?” a dispatcher asked.
“Chief of patrol, squad,” the supervisor replied, referring to CPD Chief of Patrol Jon Hein.
The supervisor noted that one CPD unit would remain on scene to document a traffic crash connected to the incident. A firearm was recovered inside that vehicle.
“And if she needs help, we absolutely help our own, alright?” the supervisor added. “If you need resources, we’ll send you whatever you need.”
Shortly before noon, the supervisor updated dispatch: “Yeah, per the Chief of Patrol, we have all pulled out. All CPD resources are clear from the scene on California as well as Kedzie.”
Just 30 minutes later, federal agents asked CPD for help near 39th Place and Kedzie.
A dispatcher relayed that an agent said “he’s one of about 30 armed Border Patrol agents, ICE. They’re being surrounded by a large crowd of people [and he is] requesting CPD. They don’t see any weapons in the crowd.”
“If you guys can immediately head down to 39th Place and Kedzie, please, and go assist them,” the dispatcher urged units leaving the station. “I’m looking on the [cameras], and there are lots of cars.”
Those CPD units responded but, per supervisory orders, stopped a couple of blocks short of where the agents said they were being surrounded. About five minutes later, they were told to leave.
“Just to confirm,” a dispatcher asked, “they were saying that they were being surrounded by that large crowd and they were requesting the police and we’re not sending?”
“Again, those are the orders we’re being given,” the supervisor replied.
Saturday’s shooting marked at least the second time this week that CPD supervisors directed officers to avoid federal enforcement actions involving ICE. On Wednesday, after Border Patrol agents detained a man at the scene of a West Side traffic crash, CPD officers initially responded but were later told to steer clear.
“The [crashed] car can sit in the middle of the street,” one supervisor said. “As long as we’re not over there, it’s all that matters.”
