Álvarez was allegedly suicidal long before the incident occurred. According to some reports, he had attempted suicide previously. In addition, he was a known methamphetamine addict, prone to delusional behavior. At the time of the train crash, Alvarez, the father of two young children, was experiencing marital difficulties. His wife, Carmelita Ochoa, filed a restraining order against him months before the incident, claiming he had become erratic and threatening to her and the children, and extremely controlling.

Police initially believed that Álvarez decided to kill himself that day, but that he changed his mind immediately before the train hit his vehicle, jumping out of the car and observing as the collision took place. He was charged with, and subsequently convicted of, 11 counts of murder with "special circumstances". Police say following investigations indicate Álvarez may have intended to cause the crash without committing suicide
