BELIZE CITY, Belize (AP) — An autopsy on the body of a northwest Missouri native who was found dead in western Belize has determined that she was strangled to death.

The post-mortem report prepared by Dr. Keyden Ken says Anne Swaney was killed by “asphyxia due to compression of the neck area, throttling and blunt force traumatic injuries to the head and neck.”

According to the Kansas City Star, Swaney grew up in Platte City before attending Northwestern University and working for ABC-Channel 7 in Chicago.

The 39-year-old woman’s body was discovered floating face-down in the Mopan River, which flows from Belize into Guatemala.

Police Superintendent Daniel Arzu told local television Friday night that an unidentified Guatemalan national who was fishing in the area was being questioned but denies any involvement in her death.

Swaney was a guest at the Nabitunich resort in the Cayo district when she was reported missing Thursday.
