Wal-Mart Shut After Chemical Is Sprayed

Authorities searched for suspects in the release of an irritating chemical inside a Wal-Mart store that sent 32 people to hospitals and shoppers fleeing for fresh air. Authorities sought at least four people believed to have sprayed the chemical from cans in six locations around the 24-hour store late Saturday. The store was closed for about eight hours. The 32 people who were taken to two hospitals in Huntington, W. Va., complained of burning eyes, nausea, throat irritation and respiratory problems. All were treated and released.
