Marc O’Leary: the true story

Marc Patrick O’Leary (whom we know in the series as ‘Chris McCarthy’) was born in 1978 in Colorado, United States.

Although there is not much information about his parents, according to the Dreshare portal, O’Leary attended high school and college in his hometown. Likewise there is no evidence that he had a brother as shown in Ubelievable.

After completing his studies Marc Patrick O’Leary spent a few years in the army. Upon leaving him, he returned to Colorado where he began a relationship with Amy Wozny in 2008, who never suspected that her boyfriend was a serial rapist.

However, there were behaviors that seemed strange to her, especially in the sexual aspect of their relationship, since Amy claimed that to get excited Marc needed to feel that the other person was scared.

When Amy Wozny found out what her partner had done, she was “running and throwing up. It was too hard for me.” she told 48 Hours.

The victims of Marc Patrick O’Leary

The first victim was Marie, an 18-year-old girl whom he abused one morning in 2008 without leaving any trace that would allow him to be identified, so the police accused the girl of lying and closed the case.

And Marc O’Leary was very methodical in ‘cleaning’ the scenes of his rapes, in addition to having a very precise knowledge of how the police system worked.

O’Leary knew that the departments did not share information, so he attacked only once in each district, ensuring that the victims were different in age and appearance, and attacking at times when they were alone to avoid witnesses.

Similarly, Marc O’Leary tried to leave the rooms in which he raped them impeccable: he forced them to bathe, took their bedding and everything he had used to tie and gag them.

This modus operandi allowed him to commit 28 cases of rape in the Colorado and Washington area between 2008 and 2011, in addition to other crimes such as kidnappings and robbery.

How was Marc O’Leary captured?

In 2011, almost by chance, Sergeant Edna Hendershot and Detective Stacy Galbraith detected similarities in two rape cases from their respective districts, and realized that it could be a serial rapist.

Both officers joined forces and began to investigate all similar reports in nearby districts.

After 40 days of exhaustive work, they found Marc O’Leary’s truck, which had been seen hanging around the victims’ homes hours before the attacks.

Once they had the search warrant, they entered his house and found evidence of all his crimes: photos of his victims and some tennis shoes whose print matched one left at the crime scene in Golden.

Thus, Marc Patrick O’Leary was arrested and put on trial accused of 28 counts of rape.

Upon interrogation, it came to light that Marc O’Leary belonged to a secret society that divided people into “alphas” and “bravos.” The alphas had the right to have sex with whoever they wanted, while the brave ones had to be subdued.

At the end of the judicial process, a Colorado judge sentenced Marc O’Leary to the maximum sentence in the state: 327 and a half years in Sterling Correctional Facility and 68 years in a Washington prison.
