An accused killer was burned to death Friday by a mob in a suburb of the Guatemalan capital, the municipal fire department said.

Residents of Mixco beat Edin Estuardo Canon before dousing him with gasoline and setting him ablaze, department spokesman Raul Hernandez told reporters.

The mob captured Canon after he allegedly shot Fernando and Erick Mendez, a father and son working together in the jewelry business.

Fernando, 53, died later at a hospital, while 23-year-old Erick was badly wounded.

Guatemala has seen 178 lynchings in 2012, resulting in 11 deaths, according to figures kept by the national ombud's office.

Vigilante justice as a widespread phenomenon in Guatemala dates from the 1996 signing of peace accords that ended the country's 36-year civil war.

The absence of police in isolated communities and pervasive distrust of the judicial system are the main reasons for the rising number of lynchings in the Central American nation, analysts say.
