The victims were Lucero Espinoza, 8; her brother, Ricardo Espinoza, 9; and their cousin, Alexis Espejo Quezada, 10. The defendants were questioned several hours after the discovery of the bodies and gave inconsistent statements as to their whereabouts at the time of the children's deaths. In the home the two men shared, police found a pair of blue jeans with what looked like bloodstains. Officers found gloves and another pair of jeans in Policarpio Espinoza's car, all with signs of blood. DNA analysis later linked the items to the murders, for which no motive was ever ascertained.
