Mexican investigators say two European cyclists did not die in an accident as first claimed - they were murdered.
The bodies of Holger Hagenbusch, from Germany, and Krzysztof Chmielewski, from Poland, were found at the bottom of a cliff in Chiapas state.
Local authorities had said the pair appeared to have fallen after losing control.
"The Polish cyclist was decapitated and had a foot missing," he wrote on Facebook.
Chmielewski sustained a head injury that may be a gunshot wound, said Mr Sánchez.
I'm surprised the mexican authorities didn't call it a murder-suicide
