The mother of a sniper involved in a fatal shooting at a Dallas ICE facility was an advocate for anti-gun laws, often criticizing members of the GOP for their stance on gun rights.

Sharon Jahn, whose son Joshua Jahn was the sniper, maintained a Facebook profile where she engaged with content from figures such as Kamala Harris and Rachel Maddow, along with the U.S. Democratic Socialists.

In the wake of the tragic Uvalde, Texas mass shooting in 2022, she posted an extensive critique on Facebook, addressing Senators Ted Cruz and John Cornyn, along with Governor Greg Abbott regarding their pro-gun policies.

She challenged: ‘Governor Abbott, Senator Cornyn, and Senator Cruz, how do you feel knowing your actions to loosen gun laws contributed to the deaths of 21 people? Do you secretly watch the news with a sinister smile? You must take pride in the gun lobby money filling your coffers. Was it worth it, Governor Abbott? What about you, Senators?’

‘When you prioritize money over people this is what you get,’ Jahn added, noting ‘blood money’ all three had taken from the gun lobby. 

She further criticized Cornyn for lacking the courage to oppose the NRA, labeling him a ‘spineless coward’ for skipping their annual meeting.

‘Why have our leaders let us down? Their greed for wealth and influence. It’s time to vote out these spineless figures and usher in leaders who genuinely care for others.’

She also posted a poem that read: ‘If we only have love, we can melt all the guns, and give the new world to our daughters and sons.’ 

Jahn was confronted by The Independent earlier Tuesday while she was sobbing.

‘I’m sorry, I can’t talk to you right now. I’m sorry, I’m so sorry. But I just can’t talk to you now,’ she said. 

The Daily Mail has reached out to Jahn for further comment.

Her son Joshua Jahn, 29, was named as the gunman who opened fire on the ICE detention center around 7am Wednesday morning, before killing himself as cops descended on him. 

Law enforcement said that the sniper perched on a roof adjacent to the facility and rained bullets on the migrants as they were being transported in an unmarked ICE van. 

Investigators said that they are still establishing a motive, but believe the shooting may have been fueled by anti-law enforcement sentiment. 

FBI Director Kash Patel released images of bullets found at the scene, showing ‘anti-ICE’ scrawled on the shells in blue ink. 

After Jahn was identified as the alleged shooter, his brother Noah told NBC News that he did not believe his brother was especially interested in politics and had not voiced his opinions on immigration before. 

‘He didn’t have strong feelings about ICE as far as I knew,’ his brother said. 

Noah said his brother was unemployed but had previously worked as a coder, and was planning on moving in with their parents in Oklahoma. 

Jahn has been pictured in a mugshot from his arrest in 2015, when he was hit with felony charges for delivering marijuana in an amount greater than 1/4 ounce. 

He was a registered independent in the 2024 election, but last voted in the Democratic primaries in March 2020, records showed.

The alleged shooter’s brother reportedly spoke before he knew that his brother had been identified as the sniper, and described him as ‘unique’ without elaborating. 

‘I didn’t think he was politically interested,’ he continued, saying he had last seen him two weeks before the shooting on Wednesday and nothing seemed unusual. 

‘He wasn’t interested in politics on either side as far as I knew.’ 

The siblings grew up in Allen, Texas, and spent their childhoods attending the Boy Scouts, the brother said. 

He added that his brother knew how to use a rifle that his parents owned, but insisted that ‘he’s not a marksman, that’s for sure.’ 

Asked about the ICE facility shooting, he remarked: ‘He would not be able to make any shots like that.’ 

As investigators descended on the scene in Dallas, images showed a poster taped to the side of a vehicle believed to belong to Jahn. 

A sign with what appears to be black splatter on the car reads: ‘Radioactive fallout from nuclear detonations that’ve passed over these areas more than 2x since 1951.’

Homeland Security spokesperson Tricia McLaughlin told CNN that the death toll stood at two as of Wednesday afternoon. A third victim was in serious condition. 

Investigators said Jahn fired ‘indiscriminately’ at the ICE office, peppering the transport van with bullets and also hitting windows in the building numerous times.  

Witness Arianny Sierra told NBC that she was in her car waiting for her husband to return from an ICE appointment in the facility when she heard shots ring out. 

‘The shots began at around 6:10 a.m. There were like 20 shots in a row,’ she said.

The victims were ICE detainees, and no law enforcement were injured in the shooting. Officials said at a press conference on Wednesday morning that the sniper opened fire ‘from an elevated position’ as migrants were inside the transport van. 

He is believed to have been found on the roof of a nearby immigration attorney’s office, WFAA reported. 

Patel said in an X post: ‘While the investigation is ongoing, an initial review of the evidence shows an ideological motive behind this attack.

‘These despicable, politically motivated attacks against law enforcement are not a one-off.’

Although the sniper appeared to target migrants in ICE custody, Texas Attorney General Ken Paxton wrote on X that the shooting represented an attack on ICE and law enforcement.

‘We will continue to do everything in our power to combat the alarming increase of targeted attacks against ICE and all law enforcement by evil, twisted individuals,’ Paxton wrote.

Vice President JD Vance added: ‘The obsessive attack on law enforcement, particularly ICE, must stop. I’m praying for everyone hurt in this attack and for their families.’

At the press conference on Wednesday, Texas Senator Ted Cruz made an impassioned plea for the end of politically motivated violence that has swept the nation in recent times.

‘We should not be putting language out there that inspires mad men to commit evil crimes,’ Cruz said. ‘Stop it, please.’

Cruz also cited the recent assassination of Charlie Kirk, telling reporters: ‘It was two weeks ago today that we saw a political assassination in Utah that tore the heart out of much of this country.’
