HOUSTON --A Texas school district says a teacher won't return to work after being accused of mocking an American-born Muslim student by asking if she was grieving because her "uncle" had died, a reference to Osama bin Laden. The teacher was put on leave after making the alleged remark May 2, hours after bin Laden was killed in a U.S. military raid. The incident involved a female student in a ninth-grade algebra class at Clear Brook High School in Friendswood, located 23 miles southeast of Houston. District spokeswoman Elaina Polsen on Monday declined to say if the teacher was fired or resigned. Polsen said the comment did not reflect school or district staff attitudes. Houston-area Muslim leaders said last week they were pleased with the district's response.
