(INSIDE EDITION) - A Prophet Muhammad cartoon contest in Texas was not the only target of an alleged ISIS supporter from Arizona, authorities have revealed.
Abdul Malik Abdul Kareem was already accused in the spring of helping plan an attack in Texas when a document released Wednesday charged him with conspiracy to provide material support to a foreign terrorist organization.
More specifically, prosecutors allege Kareem researched traveling to the Middle East to fight alongside the group and inquired about the types of explosives that would be needed to blow up a mall and the stadium near Phoenix where the 2015 Super Bowl was held, the Associated Press reports.
Authorities allege that Kareem researched the trip and sought out information on pipe bombs with accomplices Elton Simpson and Nadir Soofi.
Simpson and Soofi were killed May 3 in a police shootout outside a Garland, Texas Prophet Muhammad cartoon contest.
Kareem is accused of encouraging the two men to launch that attack.
According to the latest documents, the men allegedly practiced shooting in the desert near Phoenix early in 2015, CNN reports.
The court documents say Kareem provided the other two men, and others, with firearms at his home where they discussed the Garland attack.
The indictment claims the men watched footage from the Middle East that authorities say depicts jihadist acts of violence, war and torture.
"While watching the videos, Kareem exhorted and encouraged Simpson and Soofi to engage in violent activity in the United States to support [ISIS] and impose retribution for United States military actions in the Middle East," the indictment read.
Kareem was charged Wednesday with conspiracy to provide material support to a foreign terrorist organization, interstate transportation of firearms with intent to commit a felony, making false statements and other crimes.
Those charges came in addition to an indictment earlier this year that charged him with conspiracy and weapons charges.
Maynard previously said the case was trumped up and based largely on an unreliable confidential informant.
Kareem's attorney, Daniel Maynard, did not return an off-hours messageleft Saturday afternoon.
Maynard has previously claimed the charges against his client are trumped up and based largely upon information from a confidential informant, the AP notes.
