Daniel Nieto, 49, was shot and killed in the late hours of Saturday, August 22, 2015, in the parking lot of a Village Inn on Lomas Boulevard in Albuquerque. Police say he had arranged to meet people he knew and that the encounter was allegedly a targeted attack that escalated into a robbery and ended with gunfire.

Within weeks investigators identified two main suspects, a man and a woman. A woman was arrested in early October 2015 in Albuquerque and charged with involvement in the killing. By the end of October the male suspect, described as the primary shooter, had been located and arrested and also charged in connection with Nieto’s death.

What details about the meetup or the people involved might still help explain why Nieto agreed to that meeting?
