			 U.S. investigators are trying to piece together Mohammod Youssuf 
			Abdulazeez's travels to the region to see if he was radicalized by a 
			militant group such as Islamic State. But they have no evidence he 
			was in contact with militant groups or individuals. 
			 
			On a seven-month trip to visit family in Jordan, it is uncertain how 
			long he may have spent in the Qatari capital, a political crossroads 
			in the region. Qatar is home to jihadist supporters as well as a 
			U.S. air base. 
			 
			Abdulazeez, a Kuwaiti-born naturalized U.S. citizen, was killed in a 
			gunfight with police on Thursday after he sprayed gunfire at a 
			military recruiting center in Chattanooga, then drove to a nearby 
			Naval Reserve Center where he shot and killed four Marines. Three 
			people were wounded, including a sailor who died on Saturday. 
			 
			The shooting follows a series of attacks, or thwarted attacks, in 
			the United States and other countries by Muslims claiming to be 
			inspired by Islamic State or other militant groups. Such "lone wolf" 
			attacks by militant, radicalized U.S. Muslims acting on their own 
			pose a greater risk to the country than a large-scale operation, 
			President Barack Obama has said. 
			  
			
			  
			 
			Earlier on Monday, another source close to the probe said 
			investigators had evidence that the suspected gunman had online 
			exposure to general jihadist propaganda that may have inspired the 
			rampage. 
			 
			But they have not turned up any specific directive or exhortation 
			from a militant group such as Islamic State, according to the 
			source, who asked for anonymity when discussing sensitive 
			information. Even so, the Federal Bureau of Investigation has said 
			it is investigating the attack as an act of terrorism. 
			 
			Abdulazeez apparently did not use a laptop but could have read 
			jihadist propaganda on his smart phone, the sources close to the 
			investigation and a second source told Reuters. 
			 
			More details emerged on Monday about Abdulazeez's possible frame of 
			mind leading up to the attacks. He had drug abuse problems and was 
			worried about debt, according to his family and a diary he left 
			behind, ABC News reported, citing a family representative. 
			 
			Close friends told Reuters previously that the suspected shooter 
			drank alcohol and smoked marijuana, had received treatment for drug 
			problems, and struggled to reconcile those habits with his Islamic 
			beliefs. His family said in a statement at the weekend that he 
			suffered from depression. 
			 
			U.S. lawmakers said on Sunday they will examine possible 
			shortcomings in law enforcement or intelligence in the case, which 
			highlighted growing concern about possible Internet-based directives 
			from Islamic State leaders in Syria. 
			 
			Abdulazeez, an engineer, wrote about having suicidal thoughts and 
			"becoming a martyr" as far back as 2013 after losing his job due to 
			drug use, both prescription and non-prescription, the family 
			representative told ABC News. 
			 
			ABC did not name the family contact, who said Abdulazeez abused 
			sleeping pills, opioids, painkillers, marijuana and alcohol.

			ABC said that Abdulazeez was taking sleeping pills to deal with an 
			overnight shift at work, and was considering filing for bankruptcy 
			because he was thousands of dollars in debt. 
			 
			In April, Abdulazeez was charged with driving under the influence. 
			He had faced a July 30 court date. 
			 
			There is also evidence of family strife. Abdulazeez's mother filed 
			for divorce in 2009, alleging physical, verbal and sexual abuse by 
			his father, but the two eventually reconciled and the suit was 
			dismissed, according to court records. In her petition Rasmia 
			Abdulazeez also alleged that her husband Youssuf Abdulazeez had 
			beaten his children on occasion. 
			 
			INVESTIGATION FOCUSED ON TRAVEL 
			 
			Abdulazeez graduated from Red Bank High School near Chattanooga and 
			earned a bachelor's degree in electrical engineering from the 
			University of Tennessee at Chattanooga. On a resume posted on 
			Indeed.com, he listed three jobs since 2010, all internships. 
			 
			Abdulazeez returned from a trip to Jordan in 2014 concerned about 
			conflicts in the Middle East and the reluctance of the United States 
			and other countries to intervene, according to two friends who had 
			known him since elementary school. 
			 
			Abdulazeez went to the Middle East in 2010 and visited several 
			countries, one of his friends told Reuters. He then went to Jordan 
			in 2014 to work for his uncle, and lived with his uncle and his 
			grandparents there, he said. Both friends spoke with Reuters on 
			condition they not be named because they feared a backlash. 
			 
			According to Abdulazeez's friends, he owned handguns and purchased 
			three assault rifles on an online site, Armslist.com, after 
			returning from Jordan, using them for target practice. 
			
			
			  
			
			 
			 
			Friends said he had always liked shooting, starting with BB guns and 
			paintball, and that he enjoyed driving fast cars.
