A white supremacist allegedly stabbed an inmate at the federal courthouse holding cell in Salt Lake City, Utah, after being sentenced for a similar incident. 

On July 12, Lance Vanderstappen, 25, attacked a Hispanic male with a three inch sharpened metal object shortly after being sentenced to 63 months in federal prison for a 2001 stabbing of another man inside the Utah State Prison.

Vanderstappen, a member of the white supremacist prison gang Soldiers of the Aryan Culture (SAC), and the victim were in the holding cell with other prisoners when the alleged attack took place.

The victim suffered puncture wounds and several cuts, according to the U.S. Marshal’s Service, which provides security at the building.  Authorities said Vanderstappen smuggled the object into the federal courthouse from the state prison in Draper.

Federal prosecutors will likely file new charges against Vanderstappen following an investigation.

SAC formed in the Utah State Prison in 1997.  According to prosecutors, SAC has carried out various crimes, including conspiracy to commit murder, attempted murder, extortion and conspiracy to distribute narcotics.  Vanderstappen, one of 12 SAC members indicted last year under the Racketeer Influence and Corrupt Organizations (RICO) Act, was also involved in a courtroom brawl in December.
