Police in Jamaica say two U.S. missionaries have been found slain in a rural area of the Caribbean island that has long struggled with high rates of violent crime.

In a Sunday statement, the Jamaica Constabulary Force identified the two men as 48-year-old Randy Hentzel and 53-year-old Harold Nichols. Their battered bodies were found in bushes in separate areas of St. Mary parish.

There have been no arrests. Investigators have not issued a possible motive.

Police did not provide hometowns for the victims. Hentzel's Facebook page says he was from Donnellson, Iowa. Nichols' hometown was not immediately clear.

Both missionaries lived and worked in Jamaica for a Pennsylvania-based religious organization called Teams for Medical Missions. The two men and their families did evangelism and Bible ministry and built homes.
