An American woman killed on a remote beach in Grenada on Sunday suffered an "extensive" skull fracture and was asphyxiated, authorities said Tuesday.
The Royal Grenada Police Force told NBC News that Jessica Colker, 39, was found dead on a beach in the island's town of Saint David's.
Police spokesman Sylvan McIntyre told NBC News that Colker was walking with her husband along a "secluded beach" around midday. The husband told police that a man with a cutlass, a type of sword, attacked them. The husband escaped and Colker's body was found an hour later.
McIntyre said a suspect has been been taken into custody but has not been charged and is assisting with the investigation.
Colker was originally from Georgia and was vacationing in the Caribbean at the time of her death, according the State Department.
