The chief suspect in the killing of five U.S. service members in Chattanooga, Tenn., on Thursday had traveled to Qatar at least once during a trip to the Middle East in 2014.
The reasons for Mohammad Youssef Abdulazeez’s stopover in the Qatari capital Doha or the duration of his stay are still unknown, reports Reuters. Qatar has both native jihadist supporters as well as a U.S. air base.
Counterterrorism officials are also investigating a seven-month trip Abdulazeez took to Jordan in 2014 with his family. Officials are examining whether he became radicalized during this trip, but there is currently no evidence to suggest the 24-year-old had any contact with militant groups or individuals.
Abdulazeez, a Kuwaiti-born naturalized U.S. citizen of Jordanian descent, opened fire at a military recruiting center in Chattanooga on Thursday, before driving to a naval-reserve facility where he shot and killed four Marines. Three people were injured including a sailor who died the following Saturday. Abdulazeez was killed in a subsequent gunfight with law-enforcement officers.
On Monday, an official close to the investigation told Reuters that there was evidence that the suspect could have had access to jihadist propaganda online.
