Ernesto was a writer with neat graying black hair and goatee, and had gray eyes. He wore a blue polka dot-patterned maroon neckerchief, white shirt, and a tan suit with a pen and a pencil in its pockets around the time of his death. He usually carried a green journal.
Ernesto was found at the library with at least 23 stab wounds in his chest. According to Grace, he was first hit in the head with a blunt object, then was tied up. The killer then proceeded to torture him and stab him; the hypothesis is supported by the cigarette burns on the body. This meant that Ernesto's killer smoked.
After investigating the mountains, the player and Michelle found a bloody knife in a chest. It was sent off to Lars, who despite being drunk because of his wife's arrest, confirmed the knife, or facón, was indeed the murder weapon. Jack, who was with him, reminded Lars to inform them of the mate traces found on the handle, local tea that the killer had left traces of. This meant the killer drank mate.
Killer and motives
The killer turned out to be a librarian named Lorena Pratx.
Lorena tried denying involvement, but eventually gave in and admitted to the murder. Dropping her façade as a harmless librarian, Lorena revealed that she tortured Ernesto in order to gain information on the SOMBRA document cache he had accidentally found in the mountains, before proceeding to stab him with a facón 23 times and hiding the documents. In court, Judge Adaku sentenced her to 40 years in prison for the torture and murder of Ernesto Cárpena for SOMBRA.
