Assessment: MODERATE SUSPICION

Coral Lorenzen co-founded APRO (Aerial Phenomena Research Organization) in 1952, making it one of the earliest and most respected civilian UFO research organizations in the world. Both she and her husband Jim died within two years of each other — Jim in 1986 of cancer, Coral in 1988 of health complications. Both are listed on G. Cope Schellhorn's compilation of UFO researchers who died from "unusual cancers, heart attacks, and all manner of strange happenings." APRO dissolved after their deaths, removing one of the most important civilian UFO research organizations from the landscape.

Circumstances of Death

Coral Lorenzen died on April 12, 1988 — her 63rd birthday — in Tucson, Arizona. Her health had been declining, and she suffered from a fungal lung infection among other complications. Her husband Jim had died of cancer just two years earlier in 1986.

The deaths of both founders of APRO within a two-year window effectively ended the organization, which had been one of the most active and respected civilian UFO research groups for over three decades.

Background

APRO — Aerial Phenomena Research Organization

Coral and Jim Lorenzen founded APRO in January 1952 in Sturgeon Bay, Wisconsin — making it one of the first civilian UFO research organizations in the world. APRO:

• Operated for over 36 years (1952-1988)
• Maintained a global network of investigators and scientific consultants
• Published the APRO Bulletin newsletter continuously for decades
• Investigated thousands of UFO sighting reports with scientific methodology
• Had representatives and field investigators in over 50 countries
• Maintained a scientific advisory board that included PhDs and other credentialed researchers
• Was considered more scientifically rigorous than NICAP (National Investigations Committee on Aerial Phenomena)

Published Works

Coral Lorenzen authored and co-authored several books:

• The Great Flying Saucer Hoax (1962)
• Flying Saucers: The Startling Evidence of the Invasion from Outer Space (1966)
• UFOs Over the Americas (1968, with Jim Lorenzen)
• Encounters with UFO Occupants (1976, with Jim Lorenzen)
• Abducted! (1977, with Jim Lorenzen)

Significance to UFO Research

APRO's dissolution after the Lorenzens' deaths left a significant gap in civilian UFO research infrastructure. The organization's files — decades of investigations, witness reports, and scientific analysis — were partially preserved but much was lost.

Why This Death Possibly Raises Questions

• Both co-founders of APRO died within two years of each other, effectively destroying the organization
• APRO was one of the most scientifically rigorous civilian UFO research organizations in the world
• Their deaths are listed on multiple compilations of suspicious UFO researcher deaths
• The loss of APRO removed a critical independent check on government UFO narratives
• Unusual cancers and health complications are a recurring pattern in UFO researcher deaths documented by Otto Binder and G. Cope Schellhorn
• Coral died on her exact birthday — April 12 — which some researchers note as unusual

The Counterargument

• Both Lorenzens were in their 60s when they died, and cancer and health complications at that age are not unusual
• No specific evidence of foul play has been presented for either death
• Fungal lung infections can be caused by natural exposure, particularly in the Arizona desert where coccidioidomycosis (Valley Fever) is endemic
• Organizations frequently dissolve when their founders die, especially when no succession plan exists
• Correlation between their research focus and their deaths does not establish causation

Key Quotes from Media Coverage

"The Lorenzens gave their lives to UFO research — literally. They ran APRO for over 35 years, and when they died within two years of each other, the organization died with them." — UFO research community tribute
