Cops have filed new charges against an accused serial sex predator who they say terrorized dozens of women in Florida the 1980s.
Robert Koehler is currently being held in Broward County on the charges, which cops say fit the modus operandi of the so-called ‘Pillowcase Rapist’.
Thanks to DNA technology and samples taken from the 62-year-old suspect’s son detectives were able to link him to six cold cases.
For decades, police were unable to identify the so-called ‘Pillowcase Rapist’ who would shroud the heads of his victims – and in some cases, his own – in a pillowcase during his attacks.
But on Tuesday, the sheriff of Broward county, Gregory Tony, announced that Koehler had become their primary suspect.
‘Broward County Cold Case Unit detectives worked with Broward State Attorney’s Office prosecutors to bring charges against Koehler in a total of six sexual assault cases,’ the Broward County Sheriff’s office said, not specifying the charges he faces.
A release from the department added that ‘On at least eight occasions in 1984 and 1985, detectives believe Koehler snuck into homes in Broward County late at night or in the wee hours of the morning through unlocked doors and attacked his victims.’
One of Koehler’s alleged victims, who identified herself only as Carolyn, said in a clip aired by the department: ‘This guy is a horrible, evil, dangerous predator.’
The woman, visibly emotional, added: ‘You deserve to be put away and never come out.’

‘It makes me feel like it was worth it – like my life could make a difference,’ another emotional alleged victim, named only as Catherine, told the court of the arrest.
A third victim, whose face was blurred by the court, told court-goers Tuesday, ‘It gives me closure, a little piece of mind, knowing that he finally got caught.’
Koehler, a resident of Palm Bay, had already been in the custody prior to the news conference on Tuesday, after being arrested in 2020 for a rape of a woman in Northwest Miami-Dade in 1983.
Police revealed that DNA taken from that scene matched samples from a number of cases between 1981 to 1986 left by the ‘Pillowcase Rapist,’ Miami-Dade State Attorney Katherine Fernandez Rundle said during the event.
Investigators were able to identify Koehler by analyzing familial DNA taken from Koehler’s son, who provided police with a DNA sample after his own arrest for a 2020 domestic-violence case.
His DNA was similar enough to the suspect’s that investigators believed the unknown assailant was his father.
Cops now say 62-year-old Koehler may be responsible for as many as 45 rapes in the Sunshine State.
For years, cops struggled to discern the identity of the attacker, who would break into unsuspecting women’s apartments and homes to rape them at knifepoint.
The suspect left investigators with little to go off of, leaving little evidence behind at each crime scene.
In 1985, police formed a specialized task force tasked with catching the serial predator.
After investigating hundreds of leads, interviewing dozens of suspects, and engaging in hours of stakeouts, cops still came up empty, going off vague clues provided by the traumatized victims – and the task force was disbanded.
Koehler, however, police said Tuesday, did not stop his attacks, and was eventually arrested in 1990 after breaking into a woman’s apartment in Palm Beach County and raping her.
At the time, detectives did not link the case to the still-at-large Pillowcase Rapist, despite the similarities to the then years-old attacks that had transpired in nearby cities.
Cops revealed Tuesday that after being found guilty and convicted in the 1990 case, Koehler’s DNA was not put into a police database – further hampering their investigation.
However, nearly 30 year later, shortly after Koehler’s 2020 arrest for the Miami attack, cops began to zero in on the suspect, thanks to the hunch of one eagle-eyed cold case detective who noticed similarities between the case and previous attacks by the Pillowcase Rapist.

The presser saw cops air video of the suspect’s now elderly alleged victims speaking out against Koehler, including one who identified herself only as Carolyn (above).

Cold Case Unit Sergeant Kami Floyd began to investigate the case in 2019, and stumbled across the case of the woman who was brutally assaulted at knifepoint in her Pompano Beach apartment in June 1984.
The victim’s account of the attack said that the assailant had used a pillowcase to cover his face during the break-in, spurring Floyd to connect the dots and classify the attack as the likely work of the Pillowcase Rapist.
Police had believed for years that the same suspect was responsible for each of the attacks due to DNA samples taken from the crime scenes, but due to a lack of technology at the time time, they did not know who that suspect was.
‘At the time (of the assaults), all we had was blood typing,’ Floyd said in a video aired at Tuesday’s presser. ‘With this new technology that we have, we were able to retest the specimens and get a full DNA profile of our suspect.’
After Koehler was arrested in Miami-Dade County, Broward County investigators obtained a new DNA swab that matched original specimens taken from several suspected Pillowcase Rapist cases, Floyd said.
The Miami-Dade State Attorney’s Office soon announced that the DNA linked Koehler to at least 25 attacks, but only dished out one charge – likely a strategy from police to garner a conviction considering the time table for the crimes.
‘From the DNA that we were able to pull from our evidence, with 100 percent certainty Robert Koehler’s DNA matches the DNA from every one of our victims,’ Floyd said, after hearing from three women whose cases have since been confirmed to be the work of Koehler.
Koehler, pictured here in court in January 2020 had already been in the custody prior to the presser Tuesday, cops said, after being arrested in 2020 for a rape of a woman in Northwest Miami-Dade in 1983. He has since been linked to several other attacks in the state
Following Koehler’s arrest two years, detectives discovered what they called a ‘dungeon in progress’ in his Palm Bay home, excavated in the basement. Cops are pictured crowding around the residence during the January 2020 arrest
The Palm Bay residence cops said Koehler had excavated to build a ‘dungeon.’ Inside the residence, cops found trinkets and jewelry likeley taken from Koehler’s victims – which police said Tuesday likely could be nearly 50
‘Every single one of these women, I can’t imagine what they went through in the initial instance. But having to relive it this many years later, I’m amazed at their ability to recall, their ability to speak freely about it and so detailed.’
Following Koehler’s arrest, detectives discovered what they called a ‘dungeon in progress’ in his Palm Bay home, excavated in the basement.
Safes containing jewelry and trinkets authorities believe were souvenirs from his victims were uncovered from the subterranean lair, as well as a metal nail file wrapped in protective covering that police said could have been used as a weapon in many of the Pillowcase Rapist cases.
‘It was a hunch,’ Floyd said of linking the first case she found to Koehler.
‘It was a hunch based specifically on this case, that he used a pillowcase to cover his face, and at no point was she able to identify who he was because she didn’t know what he looked like.’
Koehler’s trial for the charges stemming from the Miami-Dade incident is scheduled for June 21 – though police say the date could get pushed back. Cops said Tuesday that he will stand trial in Broward County for the remaining six charges when that case concludes.
