Swaney disappeared on Jan. 14, 2016, and her body was found the following day, according to WLS-TV. The FBI said her body was found in the Mopan River in the Cayo district of Belize. An autopsy revealed that she had been strangled to death.
Over a year later, local authorities in the Central American country and the FBI are still trying to solve her death.
Earlier this week, the FBI announced on its website that it was offering a reward of up to $10,000 for "information leading to the arrest and conviction of the person or persons responsible for the murder of Anne Swaney."
Swaney's friend, Ji Suk Yi, told WLS-TV that they are desperate for a break in the case.
"I want to know specifically why she didn't end up going on that horse ride, why were they a horse short," Yi said. "We feel like it had to have been someone, we believe, someone there that knew her."
Swaney's colleague, John Idler, the ABC7 Chicago president and general manager, called her death a "tragic loss" for the "city of Chicago," in a statement on Jan. 15, 2016.
"I'm really without words because it is a tragic loss for our newsroom, and really for the entire station and for the city of Chicago. She was terrific at what she did," Idler said.
