September 2016 it came to light that the letter that Murrieta claimed was sent to the daycare center in 2005 had been falsified by state government officials in an attempt to divert attention and shift blame away from the government, since the fire had actually begun in an adjacent warehouse used by the state secretariat of finance to store documents. A hypothesis that was investigated was that the fire was intentionally started in the warehouse with the purpose of destroying potential evidence of excessive debts incurred by the Bours government. A federal judge ordered the Sonora Attorney General's office to launch an investigation into both Murrieta and Bours for document falsification as well as altering the scene of the crime. The entire scandal has since become emblematic of the impunity, corruption and nepotism exhibited by public officials in the country. Murder of Nepomuceno Moreno Nuñez In November 2011, peace activist Nepomuceno Moreno Núñez was gunned down in broad daylight while driving in Hermosillo; he had risen to prominence after tirelessly speaking out against organized crime and corruption and directly blaming state police for working with criminal organizations in his son's kidnapping the year prior. At a press conference less than 24 hours after his death, Murrieta emphasized Moreno's criminal past while omitting the fact he was absolved of his charges, implying that the shooting was unrelated to his recent activism. The almost-immediate criminalization of the victim garnered significant criticism from both journalists and activists. Prominent poet and activist Javier Sicilia called on the governor to fire Murrieta, saying that Moreno had sought protection from the government after receiving multiple death threats and he had failed to take action. Congress of Sonora Following his resignation from the state Attorney General's office, he registered as a candidate for the PRI nomination to the Congress of Sonora in 2012. He won a seat representing the 16th district of Ciudad Obregón southeast, and served his full term as a deputy of the LX Legislature from 2012 to 2015. He was a member of committees on audit/fiscal review, labor/public works, economic development/tourism, energy/environment, health, rules/legislative precedence, and water. In 2013 he fought for misallocated funds to be rightfully distributed to the Sonora Institute of Technology, a school he taught business law at from 1985 to 1990, noting that they had received less than half of its promised budget from the state government.
