KANNAPOLIS, N.C. (WNCN) — A man who was arrested in Kannapolis with child pornography, guns and explosives in a van had plans to carry out an act of terrorism, including trying to assassinate Joe Biden, according to court documents.

According to court documents, the man, identified as Alexander Hillel Treisman, used the alias Alexander S. Theiss.

Court documents allege that Treisman searched Biden’s home address several times and also researched state gun laws, rifle parts, and night vision goggles.

Federal agents say he posted a meme on social media, asking “should I kill joe biden?”

Before his arrest, Treisman was facing child pornography charges.

In the order, a federal magistrate judge outlined the reasons why Treisman should continue to be held in jail on the child pornography charges.

A total of 1,248 videos and 6,721 images of child pornography were found on Treisman’s devices, in addition to 637 videos and images of child pornography containing sadism and/or masochism content, according to documents.

An FBI agent testified in May, saying an abandoned white Ford van was seen by employees of a nearby bank.

Kannapolis police were called to the scene.

Through the windows, officers saw an AR-15 style rifle, a box for a Taurus .380 handgun, a cannister of the explosive material Tannerite and a box of 5.56 caliber ammunition.

The bank manager requested that the van be towed by police before an inventory search was conducted on the vehicle, court documents say.

According to court documents referencing the agent’s testimony, the search revealed, in addition to the items seen through the windows, around $509,000 of U.S. currency (which is believed to be defendant’s inheritance), books about survival, bomb-making, improvised weapons and Islam, drawings of swastikas and planes crashing into buildings and the following firearms:

  • Sig Sauer AR rifle
  • Intratec 9mm Luger
  • Lower AR receiver
  • Kel-Tec Sub-2000,
  • .22 caliber rifle marked ArchAngel
  • Russian Mosin Nagant M91/30 bolt action rifle

When Treisman was arrested, officers found drivers licenses from three different states, the order said.

According to the order, agents also discovered he had bought the weapons in states across the country, including Kansas, New Hampshire, Washignton and West Virginia.

The order said agents found child pornography on eight different electronic devices along with other pictures and posts related to plans and ideas for potential acts of terrorism, including the following:

  • A note created on October 15, 2019, found in Defendant’s Samsung S9 cell phone describing a plan to perform a mass shooting at a mall food court on Christmas or Black Friday;

In court, Theisman’s lawyer asked a testifying officer if he was aware that he had been diagnosed with Asperger syndrome at age twelve.

The officer says he asked Theisman about any mental health issues, to which he allegedly denied having any.

Treisman has not been charged with any crime related to his possession of the guns or other evidence the agents found.
