A manhunt ended in Texas when a Houston man accused of shooting and killing a deputy serving a warrant on him in the parking lot of a Dollar Tree, was fatally shot by police.

A man fatally shot a Texas sheriff's deputy Wednesday at a shopping plaza in Houston and then evaded officers for hours before shooting a K-9 that helped find him hiding under trash in a dumpster, authorities said.

An officer was hospitalized and police were searching for one person after a shooting Thursday morning in southwest Houston, officials said. Officials with the Houston Police Department provided limited details about the shooting on Twitter, saying preliminary information was that someone had shot an officer from another agency and fled on foot.
