Summary

In October 2011, a Colorado Mesa University instructor and a group of students discovered a skull near the Umcompaghre Plateau wilderness area in rural Mesa County. The students were environmental science majors performing a fire management field project on the plateau just a few hundred yards off Divide Road near the town of Whitewater, Colorado. The Mesa County Sheriff’s Office was able to determine that the skull belonged to an adult male, but there few other insights that could be gained from the partial remains. No determinations could be made about the unknown man’s height, weight, or outward appearance. It is also unclear how and when the unknown man died.

For the past decade, investigators have diligently pursued various leads in an attempt to identify the man. Initially, the skeletal remains were transferred to forensic anthropologists who determined that the skull was not related to any missing person cases in the county. In December 2011, the Colorado Bureau of Investigation conducted DNA testing and were able to produce an STR profile but a search in law enforcement databases did not return a match. In 2020, the unsolved case was entered into the National Missing and Unidentified Persons System (NamUs). The case was entered as UP64014. Despite exhaustive investigative efforts, law enforcement was not able to identify the man and the case eventually went cold.

In September 2022, the Mesa County Coroner's Office partnered with Othram to determine if advanced forensic DNA testing could help establish an identity for the man or a close relative. Skeletal remains were sent to Othram, located in The Woodlands, Texas. Othram's costs for processing the casework were provided by a DNASolves crowdfund. The Othram team is grateful to everyone that helped fund and share this case.

With evidence in hand, Othram scientists developed a DNA extract from the forensic evidence and then developed a comprehensive DNA profile for the man, using Forensic-Grade Genome Sequencing®. Once the profile was succesfully built, Othram’s in-house forensic genetic genealogy team produced new investigative leads that were provided to law enforcement.

Using the leads, Mesa County Coroner's Office investigators reached out to a potential family and eventually confirmed that the unknown man was in fact Michael John Alonzi, born December 10, 1961. The circumstances surrounding Alonzi's death are unclear and an investigation continues.
