In the month following the Old Tucson fire, several other fires were started in the area of Tucson Estates, down the road from Old Tucson; this subject was identified as the primary suspect in those fires. He was located and questioned by detectives, and faced with the evidence from the Tucson Estates fires, at which point he confessed to having started those fires. However, before he could be questioned about the Old Tucson fire, he invoked his Miranda Rights, effectively stopping any further questioning. Not enough evidence could be collected to positively identify this suspect as the arsonist in the Old Tucson fire. No other information pointing to any other individual was ever found, and the case remains open to this day.
