Jose Alberto Ruiz, a 44-year-old Hispanic man, was found shot to death inside a car on Indianapolis’ east side on May 15, 2016. His killing was one of three apparently random homicides in mid-May that also claimed Billy Boyd and Jay Higginbotham, and investigators tied the cases together because of their similar, senseless nature.

Court documents and witness testimony later showed the same attacker was responsible for the three slayings. The accused, identified in those documents as 19-year-old Johnathan Cruz, reportedly said he was inspired by the film The Purge and carried out a spree of killings and robberies. Cruz was arrested shortly after Ruiz’s body was discovered; he pleaded guilty to three counts of murder and received three consecutive life sentences without the possibility of parole.

Ruiz’s family and the neighborhoods affected were left grieving and shaken by the randomness of the violence. If anyone knew Jose Alberto Ruiz or has information that might shed more light on his last movements, please share what is known.
