One of three federal agents injured during a fiery weekend shootout at a Kansas motel remained hospitalized Monday as investigators sought to identify the body found inside the suspect's charred motel room.

Two deputy marshals were treated and released after sustaining gunshot wounds during the Saturday night confrontation in Topeka, said a spokeswoman for the U.S. Marshals Service's headquarters in Washington. An FBI agent was in good condition Monday at a hospital, said Bridget Patton, a spokeswoman for the FBI's Kansas City, Missouri, regional office.

Members of a fugitive task force were trying to arrest 28-year-old robbery suspect Orlando J. Collins at the Country Club Motel when they came under fire as they approached one of the lodging rooms, the FBI said. A fire then erupted in that room before spreading through the motel, the Associated Press reports.
