Authorities say police in northern Mississippi fatally shot a man who was suspected of killing his ex-girlfriend.

Mississippi Bureau of Investigation spokesman Warren Strain says Tupelo police shot 27-year-old Lyndarius Cortez Witherspoon of Tupelo after a chase Saturday evening.

Tupelo Police Capt. Chuck McDougald tells local news outlets police began to chase Witherspoon after an officer recognized his license plate from a law enforcement alert. McDougald says Witherspoon shot at police during the chase and after it ended at an apartment complex where police blocked in his vehicle.

Strain says Witherspoon was shot during a shootout with police.

Baldwyn Police Chief Troy Agnew says the alert was sent after 23-year-old Alexandra Caldwell was shot and killed earlier Saturday in Baldwyn.

Police say Witherspoon was black. The races of the police officers weren't immediately available.
