The hosts examine several theories about what happened to the women, from witness accounts of them boarding a boat with an unidentified man to possible connections with criminal activity.

On July 2, 1966, three young women from suburban Chicago—Patricia Blau (21), Ann Miller (19), and Renee Bruhl (20)—mysteriously vanished during a beach day at Indiana Dunes State Park. The women were last seen around noon when they entered the water. Later, witnesses reported seeing them board a boat with a man. Their belongings, including purses and a transistor radio, were found unattended on the beach, and Patricia's Buick remained in the parking lot.
Despite an extensive search operation involving the Indiana State Police, soldiers, Civil Air Patrol, Coast Guard, dive teams, and mounted sheriffs, no traces of the women were found. The search faced criticism for starting two days after the disappearance. While boat wreckage was later discovered washed ashore, police confirmed it was unrelated to the case.
Several theories emerged to explain the women's disappearance. A couple from Indianapolis reported seeing the women board a white tri-hull runabout with turquoise interior, operated by a dark-haired man in his early 20s. Home movies appeared to support this account, but neither the boat nor its owner was ever identified.
Another theory, discussed by Josh Clark, suggests a connection to criminal Silas Jane through the women's association with a horse stable. Chuck Bryant and Josh Clark mention speculation about the women being eliminated after witnessing a crime, possibly a car bombing, but no evidence supports this theory.
Family members proposed various scenarios, including the possibility that the women staged their disappearances. Patty Blau's brother suggested they might have tried to escape after witnessing a crime but were murdered instead. Others speculated that Renee Bruhl may have run away to start a new life. However, none of these theories have been substantiated with evidence, leaving the case unsolved.
1-Page Summary
The mid-1960s saw the perplexing disappearance of three young women from suburban Chicago at Indiana Dunes State Park on Lake Michigan.
On a bright Saturday morning, Patricia Blau, a 21-year-old, picked up her friends Ann Miller, 19, and Renee Bruhl, 20, to make the 60-80 miles journey from Chicago to Indiana Dunes State Park. Equipped for a day of leisure on the beach during the bustling July 4th weekend, the friends arrived by 10 a.m. and were among the estimated 9,000 people crowding the shoreline.
By noon, having spent a couple of hours sunbathing, the three women ventured into the water and were observed wading in by beachgoers nearby. This turned out to be the last confirmed sighting of the trio. Later, a couple from Indianapolis claimed they saw the women boarding a boat with a man. Witnesses also noted that the women had returned to shore for a brief period, potentially to grab a bite to eat, before presumably venturing out on another boat around three o'clock.
Concern grew when the teenage couple noticed the women's unattended personal belongings, including purses and a transistor radio. A ranger, initially dismissing their absence as partying, collected the items to prevent theft. However, the gravity of the situation became apparent when Patricia’s father reported them missing, 18 ...
The Disappearance and Timeline of Events
The search for missing women faced criticism for its delayed start and ended with no evidence found, leaving the case unsolved.
Critics have highlighted a significant delay in launching the search for the missing women.
Despite the delay, extensive searching employing various groups and methods took place. However, no trace of the women was found after the search operations. The women seemed to have vanished without a trace, and their disappearance remained a mystery, with the case unsolved despite the efforts.
Adding another layer to the case, boat wreckage that included styrofoam, seats, and an oil can was found washed ashore. But, police confirmed that no ...
The Search Efforts and Lack of Evidence
A perplexing case leaves authorities and families searching for answers regarding the fate of three missing women. Theories abound, but evidence remains elusive.
A couple from Indianapolis on the beach that day reported seeing the three women enter the water and interact with a dark-haired man in his early 20s, who arrived in a white tri-hull runabout with a turquoise interior. They were seen getting onto the boat. Home movies appear to support these eyewitness accounts, showing the women on a small runabout. Despite these leads, the boat and its owner were never identified, causing the case to go cold.
The authorities released a description of the boat with a turquoise interior and pursued the sighting of a tri-hull runabout, but neither the boat nor the owner was found. The case subsequently went cold, with the man named Ralph, who lived with the Largo couple that operated an underground abortion clinic and matched the description of the man with the boat, verified to have been there that day.
Patty and Anne had associations with a horse stable linked to known criminal Silas Jane. Josh Clark references their connection to the criminal ring run by Cy, Silas's brother. They perhaps even witnessed a car bombing by this organization. Chuck Bryant and Josh Clark mention an associate of Silas filing an insurance claim for a boat that sank around the disappearance, speculating that the women could have been eliminated to prevent them from talking about a crime they witnessed. However, this link to Silas Jane and the crime remains speculative without direct evidence.
The theory that the women were removed to ensure their silence about a crime they may have seen is purely speculative. One version of this theory includes their possible eyewitness accounts to the rigging of a firebomb on a car related to the stables, but no evidence substant ...
