District Attorney Vern Pierson called Holt
“a very successful predator”
-
What happened: Two cold murders in South Lake Tahoe — Brynn Rainey, 27, in 1977, and Carol Andersen, 16, in 1979 — have finally been attributed to a suspect. El Dorado County District Attorney Vern Pierson revealed this week that DNA and genealogy evidence point to Joseph Holt, a real-estate worker who died in 2014.
-
How it was solved: The El Dorado County Cold Case Task Force partnered with Parabon NanoLabs, using genetic genealogy — building a “family tree” from crime scene DNA, matching it through public genealogy databases, then confirming the suspect via DNA from a family member and a personal item (a toothbrush).
-
Background of the cases:
• Rainey’s body was found partially buried near Stateline Stables in South Lake Tahoe in August 1977, a month after she was last seen.
• Andersen disappeared in 1979 after attending a party; her battered body was later found off a road, and evidence showed she had been bound and strangled. -
Who is Joseph Holt: Born in 1947, raised in San Jose, educated at UC Berkeley. He moved to South Lake Tahoe in the mid-1970s and worked in real estate there. He died in 2014. He was never previously considered a suspect until the recent DNA work.
Timeline & Key Players
| Year | Event |
|---|---|
| 1977 | Brynn Rainey, 27, disappears and her body is later found near Stateline Stables. |
| 1979 | Carol Andersen, 16, disappears after a party; her body is found on Sundown Trail. |
| 2007 | El Dorado County establishes Cold Case Task Force. |
| 2012-2013 | Initial DNA profiles developed, but no match in national database. |
| 2017 | DNA profiles from both cases are linked as coming from the same person. |
| 2018 | Task force, working with Parabon NanoLabs, zeroes in on Joseph Holt. Family cooperation yields samples (son’s DNA, toothbrush), confirming match. |
| 2019 | Public announcement made. Families express relief. |
Impacts & Next Steps
-
Closure for families: The identification gives long-absent answers to families of Brynn Rainey and Carol Andersen. While no trial can take place since Holt is deceased, confirmation of the killer brings emotional and perhaps legal closure.
-
Use of emerging technology: These cases show how genetic genealogy can revive cold-case investigations, even those decades old. It relies on public DNA databases, forensic analysis, and cooperation from family members. Some privacy issues are debated, but in these instances stakeholders say families supported the use.
-
Further investigations: Authorities are now investigating whether Holt may be responsible for other unsolved crimes in El Dorado County and possibly elsewhere.

Key Facts about Joseph Holt
| Category | Details |
|---|---|
| Full Name | Joseph Stephen Holt |
| Birth | November 8, 1947 |
| Death | April 6, 2014, in South Lake Tahoe, California. Cause of death: heart attack (and other complications) |
| Early Life & Education | Grew up in San Jose (or was born there, depending on source). Graduated from Cupertino High School. Attended the University of California, Berkeley. |
| Residence & Occupation | Moved to South Lake Tahoe in 1974. He was in the real estate business—working, among other things, owning rental properties. He lived in various homes around South Lake Tahoe; at time of the murders, he lived within a couple miles of where the bodies were found. |
| Known Crimes Linked | Convincingly tied by DNA (including genealogy databases) to two murders: • Brynn Ellen Rainey, 27, killed in 1977. Found in a shallow grave near Stateline Stables, South Lake Tahoe. • Carol Ann Andersen, 16, killed in 1979. Found near the side of a road in the Tahoe area. She had been bound and strangled. |
| How Identified | Using genetic genealogy: DNA evidence from the crime scenes (blood stain on Brynn Rainey’s shirt, and body of Carol Andersen), matched via public genealogy-database trees (e.g. GEDmatch) to Holt. Support came through DNA from his son and from a toothbrush belonging to Holt. |
| Status as Suspect | He was never arrested (he died in 2014). Identified formally as suspect in 2018–2019. No known criminal history before these identifications. His family members say they had no knowledge. |
Additional Details & Unresolved Questions
-
A search of Holt’s property (garage) after his death (via warrant) uncovered items that raised suspicion of other criminal conduct: for example, a newspaper clipping about a 1975 Los Gatos shooting (a man burglarizing a vehicle, fleeing, etc.) which had a sketch at the time that “strongly resembles” Holt. Police are investigating whether that crime might also be linked.
-
At time of murders, Holt reportedly lived close enough to the crime locations to make them geographically plausible (within ~2 miles) to both crime scenes.
-
His known victims were both sexually assaulted, bound or shown signs of binding (in Andersen’s case wrists binding marks) and strangled or suffocated. Cause of death in Rainey’s case was hard to determine due to state of decomposition, but pathology favored strangulation or suffocation.
-
Investigators believe it’s highly likely Holt had additional victims / incidents that might be tied to him, given the gaps between known crimes, his mobility (spending time in both Lake Tahoe area and San Jose), and possession of possibly-related evidence (e.g. the Los Gatos case).
Uncertainties & What Is Not Known
-
Motive: There is no publicly available evidence about motive (why he committed these crimes) beyond the sexual assault and the opportunity/location.
-
Exact timeline of movements: While we know some locations and approximate residences, detailed records of where Holt was at every relevant time (other potential crimes) are not fully public.
-
Whether he committed other crimes: Investigations are ongoing; law enforcement is asking the public for tips about other unsolved offenses that may match his pattern.
-
Full criminal history: Holt had no prior criminal record (at least none known or documented in public sources before these cold-case links).
