Since 2006, the FBI has been able to recognize the voice of Elton Simpson, one of the men suspected in the Texas shootings outside a contest featuring cartoons of the Muslim Prophet Muhammad.
Agents recorded the young man from Phoenix talking about fighting nonbelievers for Allah. About plans to travel to South Africa and link up with “brothers” in Somalia. About using school as a cover story for traveling overseas.
Simpson was arrested in 2010, one day before authorities say he planned to leave for South Africa. But despite more than 1,500 hours of recorded conversations, the government prosecuted him on only one minor charge, lying to a federal agent. Years spent investigating Simpson for terrorism ties resulted in three years of probation and $600 in fines and court fees.

Then, on Sunday, two men whom authorities identified as Simpson and Nadir Soofi opened fire in a Dallas suburb on an unarmed security officer stationed outside the contest. The officials spoke only on condition of anonymity because they were not authorized to discuss the investigation by name.
The deliberately provocative contest had been expected to draw outrage from the Muslim community. According to mainstream Islamic tradition, any physical depiction of the Prophet Muhammad, even a respectful one, is considered blasphemous, and drawings similar to those featured at the Texas event have sparked violence around the world.
Simpson and Soofi were wearing body armor, and one shot the security officer in the leg. Garland police spokesman Joe Harn said Monday that a single Garland police officer subdued the two gunmen but that after his initial shots, SWAT officers nearby also fired at the two men. Harn said police don’t know who fired the lethal shots.
The security officer was treated for his injury at a hospital and released.
Homeland Security Secretary Jeh Johnson said in a statement Monday that law enforcement authorities are investigating the men’s motives and all circumstances surrounding the attack.
“While all the facts are not in yet, last night’s attack serves as a reminder that free and protected speech, no matter how offensive to some, never justifies violence of any sort,” Johnson said.
Simpson, described as quiet and devout, had been on the radar of law enforcement because of his social media presence, but authorities did not have an indication that he was plotting an attack, said one federal official familiar with the investigation. Less was known about Soofi who appeared to have never been prosecuted in federal court, according to a search of court records.
Simpson had worshiped at the Islamic Community Center of Phoenix for about a decade, but he quit showing up over the past two or three months, the president of the mosque told The Associated Press.
A convert to Islam, Simpson first attracted the FBI’s attention in 2006 because of his ties to Hassan Abu Jihaad, a former US Navy sailor who had been arrested in Phoenix and was ultimately convicted of terrorism-related charges, according to court records. Jihaad was accused of leaking details about his ship’s movements to operators of a website in London that openly espoused violent jihad against the US.
In the fall of that year, the FBI asked one of its informants, Dabla Deng, a Sudanese immigrant, to befriend Simpson and ask for advice about Islam. Deng had been working as an FBI informant since 2005 and was instructed to tell Simpson he was a recent convert to the religion.
Over the next few years, Deng would tape his conversations with Simpson with a hidden recording device accumulating more than 1,500 hours of conversations, according to court records.
“I’m telling you, man, we can make it to the battlefield,” Simpson is recorded saying on May 29, 2009. “It’s time to roll.”
In court, prosecutors presented only 17 minutes and 31 seconds during Simpson’s trial, according to court documents.
“I have to say that I felt like these charges were completely trumped up, that they were just trying to cover up what had been a very long and expensive investigation and they just couldn’t leave without some sort of charges,” Simpson’s attorney, Kristina Sitton, said.
Sitton described Simpson as so devout that he would not even shake her hand and would sometimes interrupt their legal meetings so he could pray. She said she had no indication that he was capable of violence and assumed he just “snapped.”
On Monday, federal agents spent hours at a Phoenix apartment complex where the men apparently lived.
Simpson was quiet, never angry and a regular on the basketball court playing with young members of the mosque, said Usama Shami, president of the Islamic Community Center of Phoenix where Simpson worshipped for years.
