APD: Detectives investigating Aurora link to accused serial rapist

Marc Patrick O'Leary

AURORA | Police said Monday they continue to investigate an accused serial rapist who may have attacked a woman in Aurora in 2009. 

Marc Patrick O’Leary, 32, has not been charged in connection with the Aurora case, a police spokesman said, but investigators with the department’s sex crimes unit continue to investigate him. 

O’Leary was arrested in February at his Lakewood home and charged with attacking two women in separate attacks, one in Golden and one in Westminster. 

Police said at the time of O’Leary’s arrest the attacks were both committed by strangers and had many similarities. As the investigation expanded, authorities say they discovered a similar attempted sexual assault in Lakewood in July.

Aurora police said at the time investigators from Aurora believe O’Leary could be connected to an October 2009 sex assault on a woman in southeast Aurora.

In the Aurora case and the others O’Leary is accused of, the attacker was a stranger to the victim and attacked them in their home, police said.

O’Leary appeared in court Monday for a preliminary hearing where a judge ruled there was ample evidence for him to stand trial on 32 charges against him, a spokeswoman for the Jefferson County district attorney’s office said. 

He is set for arraignment in May. 

According to a 9News report on the hearing, O’Leary took pictures of his victims during the assaults and told them he had been stalking them before the attacks. The report also said DNA evidence tied O'leary to the Aurora case.
