 In October 2012 , new details emerged in her murder investigation . Charges were brought against Jorge Antonio Hernández Silva ( alias El Silva ) and José Adrián Hernández Domínguez ( alias El Jarocho ) , two men who were alleged to have murdered Martínez Pérez . Silva , who had already been arrested , confessed to the murder . According to Silva 's confession , the reporter knew Domínguez and therefore allowed both of them into her house on the night of her murder . After some conversation , Domínguez grew angry and started beating Martínez Pérez with the intention of forcing her to reveal where she hid her money and other valuable possessions . Silva then joined his accomplice in the beating until they killed her . Investigators said that the attackers had plunged the journalist 's head into a toilet bowl , hit her on the head several times with brass knuckles , and threw her against a tub , where she cracked her skull . Martínez Pérez unsuccessfully tried to defend herself by grabbing a kitchen knife and stabbing one of the attackers in the forearm , but they managed to outweigh her because she only weighed 108 lbs ( 48 @.@ 9 kg ) . Both men then stole a plasma TV , two cellphones , a laptop computer , a camera and a small box , and the journalist 's wristband from her home before leaving the crime scene .
