Louisiana police officer shot dead; victim stabbed to death

SUNSET, La. -- A police officer was shot and killed Wednesday when he responded to a call from a house where three women had been stabbed, one fatally, said the sheriff of St. Landry Parish.

The man accused in the attacks drove from the house in Sunset and into a convenience store about three blocks away, barricading himself in an office, St. Landry Parish Sheriff Bobby Guidroz said.

He said SWAT team members lobbed tear gas and "C-gas" into the building, then broke in using hammers and fire axes to arrest Harrison Lee Riley Jr., 35, of Arnaudville, about 8 miles from Sunset.

Guidroz identified the dead as Officer Henry Nelson, 51, and Shameka Johnson, 40.
