Chile accuses volunteer firefighter, ex-forestry official with causing blaze that killed 137
The court in Valparaiso ruled the two men, who were arrested Friday, could be held for 180 days while they are investigated.
The chief prosecutor in the case, Osvaldo Ossandón, told journalists that the main suspect is Francisco Mondaca, a 22-year-old volunteer firefighter in Valparaiso who is accused of physically starting the fire. He said flares and fireworks were found in Mondaca's vehicle.
The other suspect was identified as Franco Pinto, a former employee of the National Forest Corporation. He is accused of planning the crime.
The regional prosecutor for Valparaiso, Claudia Perivancich, said investigators have evidence the two men agreed "in advance to carry out conduct of this type when the weather conditions were adequate."
Prosecutors said there was an economic motive behind the plot, that is providing more work in fighting fires. They said they had not ruled out the possibility of more people being involved.
The commander of the Valparaiso Fire Department, Vicente Maggiolo, said, "We are very dismayed by the situation."
Maggiolo called it an isolated incident and said it should not tarnish the work of the fire department. "We have been saving lives for more than 170 years," he told TVN.
Christian Little, executive director of the forestry department, described the detention of a former official as "a pain" for the agency.
Both the fire department and forestry agency said they would tighten hiring procedures.
The megafire began February 2 in the Lago Peñuelas nature reserve, in the central region of Chile, and for several days burned several communes, including destroying more than 10,000 homes. It is considered Chile's worst tragedy since a magnitude 8.8 earthquake killed more than 500 people on February 27, 2010.
