CHICAGO -- A Belize police spokesman says nothing was found on a person of interest to tie him to last week's killing of Chicago online executive producer Anne Swaney, reports CBS Chicago.
The spokesman said at this point police are looking at other angles, reports the station.
An autopsy on the body of Swaney, 39, a U.S. tourist found dead in western Belize has determined that she was strangled to death. She died from "asphyxia due to compression of the neck area, throttling and blunt force traumatic injuries to the head and neck," according to the post-mortem report prepared by Dr. Leyden Ken on Friday night. Swaney worked for ABC-channel 7 in Chicago.
Her body was discovered Friday morning floating face-down in the Mopan River, which flows into Belize from Guatemala.
A Guatemalan man was initially taken into custody after he was seen near the Mopan river where Swaney was found dead in the water. He told authorities he was fishing.
Belize police charged him with illegal entry into the country and he's been sentenced to six months in prison.
Swaney was vacationing at the Nabitunich resort in the Cayo district when she was reported missing Thursday.
Police say members of a tour group she should have been part of returned to the resort and couldn't find her.
Her belongings were later found on a deck by the riverside where she had gone to do yoga exercises.
Swaney's funeral is set for Saturday, in her hometown in Missouri.
