A Puerto Rico police official says a brother and sister from Florida have died in an apparent murder-suicide at a tourist hotel on the island.

Police Capt. Diana Crispin identifies the pair as 28-year-old Kimberly Katherine Radcliffe and her brother 32-year-old Thomas Brian Radcliffe. Both are from Bonita Springs, Florida.

The two were found Sunday in the upscale San Juan Water Beach Club Hotel in the Isla Verde tourist district. Crispin said Monday that the incident was still under investigation but that authorities believe Thomas Radcliffe shot his sister before turning a gun on himself. They had apparently been on vacation in the U.S. island territory for about a week.
