Jan. 3, 2007:

A student was shot to death at his high school in Tacoma, Wash., as classes about to start Jan. 3, 2006, and police were searching for the gunman, officials said.

The student's age and details of the 7:30 a.m. shooting at Foss High School were not immediately released, but police spokesman Mark Fulghum said no one else was believed to be injured. He said police were trying to determine what prompted the attack.

The suspect was believed to be another student, and school district spokeswoman Peggy Holmgren said there were witnesses to the attack.

The school was locked down after the shooting. By about 8:30, police had secured the building and students were being sent home, Tacoma School District spokeswoman Pam Thompson said. Classes were canceled for the rest of the day.
