Authorities say Henderson claimed he did not know about the images on his devices.

BEXAR COUNTY, Texas — A man now faces child pornography charges after allegedly threatening to commit mass violence on specific groups of people back in July, according to the Bexar County Sheriff’s Office. 

On July 12, BCSO says they arrested 39-year-old Nathan James Henderson after they received a “credible tip” in regards to threats of mass violence and possession of illegal explosive components.

An affidavit states, when Henderson’s cousin paid him visit on July 4, Henderson allegedly made “alarming and extremist” threats to kill Jewish and Black people, along with unnamed government officials with weapons and homemade explosive devices.

Henderson also allegedly voiced his admiration for Luigi Mangione and wished to emulate his actions.

Based on photos and information provided by Henderson’s cousin following his visit on July 4, a search warrant was executed on his home north of San Antonio. As the investigation progressed, investigators found more “alarming material” on Henderson’s devices that had been seized. 

Authorities said they found 548 media files including explicit images of children under 10 in sexually explicit conduct. 

According to BCSO, Henderson claimed he did not know about the images on his devices. 

An arrest warrant was issued and Henderson was taken to the Bexar County jail for the added charge of Possession of Child Pornography with over 10 visual depictions.
