A police chief says officers shot and killed a man in an exchange of gunfire after they pumped tear gas into his apartment during a standoff. Bell says Smith shot through his door at an officer who responded to a call that Smith was threatening other tenants at the Brookhaven Apartments. Brookhaven police Officer Kenneth Collins was lightly wounded when debris from gunfire hit him, but Bell says he continued work after being bandaged. Warren Strain, spokesman for the Mississippi Department of Public Safety, says the standoff in Brookhaven began after 6 p.m.
