CHICAGO - Two men charged with first-degree murder in the death of a 15-year-old Chicago honor student were ordered held without bail on Tuesday at a hearing where prosecutors contended the shooting happened while they were hunting for members of a rival gang.

Hadiya Pendleton died after being shot in a park about a mile from the Chicago home of President Obama on Jan. 29, just days after she performed during Obama's inauguration festivities in Washington.

Prosecutors said Michael Ward, 18, and Kenneth Williams, 20, were in a vehicle circling the park when they spotted Pendleton's group and thought they were rival gang members. Williams handed Ward a gun, and Ward went after the group, shooting at least six times, prosecutors said. "Ward admitted he snuck up on the group and they didn't see him coming," prosecutor Jennifer Sexton said.
