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.

The officer who died was identified as Jesus Vargas, a 17-year veteran of the Brazoria County Sheriff's Office. Police later killed the suspected shooter, 56-year-old Robert Davis III, after an hours-long manhunt.

A manhunt ensued and during the search, a U.S. Marshals Service K-9 officer named Rocky alerted to a dumpster behind a shopping center causing Davis to emerge from his hiding spot and shoot the K-9 twice, police said during a news conference. Davis was fatally shot when U.S. Marshals Service deputies returned fire.

A DPS helicopter rushed federal K-9 officer Rocky to the Westbury Animal Hospital after he led authorities to a murder suspect who was hiding in a dumpster. Investigators say the dog's action saved many lives.

A Brazoria County deputy was shot and killed in the line of duty on Wednesday. A K-9 officer is also being treated for gunshot wounds.
