On the evening of October 12, 2017, 53-year-old Nicholas Encalade was visiting Iron Horse Park near Tucson’s Rattlesnake Bridge with an adult woman when two young men approached and demanded their belongings. The victims handed over about five dollars and some jewelry, but one assailant produced a gun and shot Encalade shortly after 7:30 p.m. First responders found him with gunshot wounds and he was taken to Banner University Medical Center, where he was pronounced dead.

Police quickly linked a second shooting a short distance away to the park attack and found a wounded man there who was later identified as one of the two suspects. Early descriptions said the other suspect fled on foot; investigators focused on Daren Encinas-Pablo and Joseph Anthony Santos. Encinas-Pablo was later convicted of first-degree murder and sentenced to life with parole eligibility after 25 years; Santos pleaded guilty to felony robbery and received four years’ probation.

Did anyone in the Iron Horse Park area that night see the two men approaching the victims or notice suspicious activity near Rattlesnake Bridge?
