Newly unsealed federal court documents reveal three Phoenix men linked to a plot to commit mass murder at an event in Garland, Texas on May 3 wanted to join ISIS.

Newly unsealed federal court documents reveal three Phoenix men linked to a plot to commit mass murder at an event in Garland, Texas on May 3 wanted to join ISIS.

The 12-page document laid out why the U.S. Attorney's Office in Phoenix felt Abdul Malik Abdul Kareem should be detained while awaiting trial by indicating "he is a grave danger to the community and a flight risk."

12 News went to court along with other media outlets, and late Thursday U.S. District Judge Susan Bolton unsealed the government's brief in support of detention for Abdul Kareem.

The U.S. Attorney's Office did not object to the records being released and it's unclear why the records were sealed to begin with.

Abdul Kareem was indicted on June 10 for allegedly plotting an attempted mass murder with Nadir Soofi and Elton Simpson on attendees of the Muhammed Art Exhibit and Contest at the Curtis Culwell Center in Garland.

Soofi and Simpson were killed after they began shooting with assault rifles at security guards and law enforcement officers. The indictment alleges Abdul Kareem was a co-conspirator in the failed attack. And that he provided firearms to Simpson and Soofi and went practice shooting with them in remote desert areas.

The documents reveal Simpson and Soofi had a cache of weapons including an "Elk River Tool and Die, Inc., ERTD Rifle 5.45 x39 caliber, Keltec Sub-2000 9mm rifle, Hi-Point C9 9mm pistol, Romarm/Cuir Draco 7.62x39 caliber, Taurus 605 5-shot revolver, a Jimenez Arms J.A. nine 9mm pistol and well over a thousand rounds of ammunition."

The document also shows, on May 15, the Federal Bureau of Investigation paid a confidential informant $500. That informant told law enforcement Abdul Kareem wanted to obtain pipe bombs and silencers.

The document shows on May 8 the informant, "engaged in a consensually recorded, coded telephonic conversation" with Abdul Kareem. Here is an excerpt:

Informant: "I found some things you asked me about a while ago."

Abdul Kareem: "I know what you talking about...what was the number?"

Informant: "Like, 350."

Abdul Kareem: "For real?"

Informant: "Yeah, but I mean, there are cheaper ones … I just don't know … that was just for a really nice one … he had some for like a bill-fifty, a hundred bucks."

Abdul Kareem: "Yeah, we'll get together."

According to the document, the confidential informant was interviewed by the FBI around May 14 and told agents Abdul Kareem had previously told him about a plot to use explosive devices during Super Bowl XLIX in Glendale in February. In an earlier interview the informant told FBI agents that Abdul Kareem, Simpson and Soofi all stated that they would like to join ISIS, records show. But says nothing more and provides no physical evidence to corroborate what the informant told the FBI.

What's more, the credibility of the informant was questioned due to a recent arrest for domestic violence, kidnapping and adult sex trafficking.

The document lends some insight into a 2012 search warrant that was executed at the apartment of a man living in Phoenix. The investigation centered around the creation of fraudulent Arizona State University degrees and the man lived with Abdul Kareem and Elton Simpson.

The feds seized a laptop that belonged to Abdul Kareem and a flash drive that was used by him which contained radical Islamic documentation.

Forensic testing was done on both and in the recycle bin of the laptop, investigators found a document used by al-Qaeda affiliates to evade detection by authorities. According to the document, the flash drive contained information about using weapons of mass destruction. One was titled: "Training that makes killing civilians acceptable."

What we still don't know is why after the 2012 search warrant was executed Abdul Kareem was never arrested and seemingly fell off the FBI's radar only to resurface after the Texas shooting.

Friday we put a call into Dan Maynard, Abdul Kareem's attorney but we have not yet heard back from him.
