A slain soldier with Houston ties returned to Houston on Wednesday.
U.S. Army Staff Sgt. Kashif M. Memon's body arrived at George Bush Intercontinental Airport about 11 a.m.
Memon, 31, was one of two soldiers who died Thursday when their unit was attacked by small arms fire in Afghanistan, Army officials said. Someone in an Afghan National Police uniform turned his weapon against the soliders, Army officials said.
Authorities were trying to determine whether the attacker was an Afghan security forces member or an insurgent disguised in a government uniform.
Taliban leaders have claimed responsibility for the shooting, saying in an emailed statement that a member of the Afghan security forces shot the two men and then escaped to join the insurgents.
It was the second suspected insider attack in two days.
Memon leaves behind a pregnant wife and two sons.
