The Arizona Department of Public Safety (DPS) and the Maricopa County Office of the Medical Examiner (MCOME) have positively identified a pedestrian as Antonio Rodriquez-Noyola, 48-years-old at the time of his death, who was struck and killed by a motor vehicle on May 3, 1986. Rodriquez-Noyola was struck in the eastbound lanes of I-10 near Warner Road at 1:50 a.m. that day and his identity had remained unknown until the recent identification. The motorist who struck Rodriquez-Noyola stopped at the scene and was not charged criminally.

Rodriquez-Noyola was identified as part of an ongoing investigation funded by a federal grant through the Arizona Criminal Justice Commission and National Institute of Justice. A DPS detective and two criminalists worked together with a MCOME Medicolegal Death Investigator and Forensic Anthropologist on this case. Through their combined efforts, DPS investigators were able to locate fingerprints taken from the decedent at the time of his death and compare them to a new national database operated by the FBI and obtain a positive match. DNA confirmation and next of kin notification are pending.

The body of Rodriquez-Noyola was originally interred in Twin Buttes Cemetery and will be reinterred back at Twin Butes Cemetery, and will be available for family members to relocate. DPS is continuing to work with the MCOME to positively identify remains from cold cases with the support of federal grant funding.


This project was supported by a grant awarded by the National Institute of Justice, Office of Justice Programs, which also includes the Bureau of Justice Statistics, the National Institute of Justice, and the U.S. Department of Justice.
