Given the evidence lost in this case in the early days, the only way the actual killers are going to be found is likely with DNA. And guess what, there are three DNA profiles that have yet to be run through any database, state or federal.
Three DNA profiles-1 female, 2 male- were lifted off items recovered from the McStay graves, identified through a verified process, and all work done by accredited labs. Yet, the San Bernardino County District Attorney’s office has not run the DNA through CODIS or the California State Database.
People v. Merritt True Allele Analysis
The final analysis performed by True Allele is CODIS ready. Riverside County just solved a cold case using a DNA profile generated by True Allele analysis. Riverside County ran that profile through the database and found their suspect. He was convicted March 2019. People v. Torres. (Norma Lopez’s murder). And from what I gather, reading the media on this case, but for that DNA profile the suspect would never have been found.
This advancement in DNA analysis is being utilized across the country. People are being convicted and exonerated by way of it.
The major expense has been taken care of. What possible harm could there be in entering the profiles into the state and national databases? Why would we risk letting anyone involved in this crime get away?

General History and Overview of Probabilistic Genotyping
In early search warrants SBC investigators theorized that there had to be more than one person involved. And there is lots of evidence to suggest they were right.
Indicators that more than one person was involved in the McStay murders:
- Signs of life in the McStay home on the 4th, after the vehicle thought to be the killer’s is captured leaving on a neighbor’s surveillance.
- Two sets of tire tracks at the graves of different widths.
- Three DNA profiles extracted from items in the graves
- The overall complexity and many moving parts of the murders.
- Evidence pointing to the McStays abducted and taken from their home alive
