CHATTANOOGA, Tenn. – As neighbors and friends tried to understand why a lone gunman launched two brazen attacks on military sites that left four Marines dead, investigators searched for terrorist ties but so far had found none, authorities said.
Knoxville FBI Special Agent in Charge Ed Reinhold told a late-night news conference that authorities had no leads linking the gunman to international terrorist organizations.
"There is no indication at this point that anyone else was involved," he said late Thursday.
Although federal officials identified the gunman as Mohammod Youssuf Abdulazeez, there were several other spellings in his school and other records. The 24-year-old engineer, described by friends as hard-working and deeply religious, died during the attacks that also injured at least three people, including a city police officer.
Abdulazeez lived in Hixson, an upscale neighborhood in the northern section of the city. Many homes in the quiet cul-de-sac where he lived flew U.S. flags at half-staff as a memorial to those who died in the attack that began Thursday morning and lasted about half an hour.
"They were long-standing, good neighbors - just great people," Mary Winter, 32, head of the Colonial Shores Neighborhood Assn., said of the Abdulazeez family. They attended Fourth of July cookouts and other regular festivities, she said.
"He just seemed like a very nice, very polite boy," she said. "We don't know what happened. Everybody is very shocked."
So was Chattanooga's Muslim community.
