Updated | Investigators on Friday began reviewing a months-long trip the suspected Chattanooga shooter took to the Middle East in 2014, including a visit to Jordan and possibly a trip to Yemen, according to Reuters.

They are reviewing information to determine if he had contact with any extremists.

The FBI identified 24-year-old Muhammad Youssef Abdulazeez as the shooting suspect who allegedly killed four Marines and critically injured a Navy sailor Thursday morning at two separate Naval Reserve facilities in Chattanooga, Tennessee. It has been reported that he blogged about Islamic subjects and his father was once investigated for terrorist ties.

Local, state and federal officials are involved in the investigation, which is being led by the FBI.

FBI Special Agent Ed Reinhold on Thursday night told reporters that officials didn't have information that directly tied him to an international terrorist organization.

This is a developing story and will be updated as more information becomes available.
