AURORA, Colo. - The DNA evidence that led police to arrest a suspected serial rapist was two hairs found on a fitted sheet from a victim's bed, according to an arrest affidavit obtained by 7NEWS on Wednesday.
Two women who told police they were raped said they feared for their lives and the safety of their family members who were in the home at the time of the attacks, according the document.
Cameron Washington, 30, admitted to breaking into three apartments, but denied sexually assaulting anyone, police said.
Washington is accused of two sexual assaults and a third attempted sexual assault between Nov. 22 and Nov. 30. The cases occurred in two apartment complexes that are separated by a wooden fence, located in the 900 block of South Ivory Circle and the 800 block of South Chambers Road.
The 31-year-old woman who lives on South Ivy Circle told police on Nov. 22, she woke up around 4:30 a.m. and saw a man unplugging her red Dell laptop from her nightstand. He apparently entered by removing a screen through the sliding glass window. She said the man held up a knife that was about 8 inches long and demanded money.
The woman told police the man told her to sit on her bed and pull his pants down. Then he forced her to get on her hands and knees and raped her, she said.
During the alleged sexual assault, the woman said the suspect told her, "Your daughter is pretty." The woman said her 9-year-old daughter was asleep in another room in the apartment and she was afraid that he would assault her next and pleaded, "No, please not my daughter."
But she said he did not mention her daughter again.
After the man was done, he told her to open the door for him. After she did, he walked calmly out her front door carrying her laptop and the $60 in cash he grabbed from her house.
On Nov. 28, another woman reported being raped by an unknown intruder. That 35-year-old woman says her mother was in the bedroom across the hall. She told police she woke up and heard a man say, "Shut up, I have a gun." She said she did not call for help because she was afraid he would hurt her mother.
During the assault, she asked him what she wanted, and he replied, "money and sex."
The third incident happened on South Chambers Road on Nov. 30. The 23-year-old woman in that case said she screamed and yelled when she woke up and found an unknown man standing over her bed. She said he climbed out through a window.
Washington faces charges of first-degree sexual assault, first-degree burglary, felony menacing and theft. He is being held in the Arapahoe County Jail.
Two hairs were collected from a fitted sheet from one of the women's bedrooms. DNA from that hair led police to arrest Washington late Monday night at his Denver home, said Aurora police spokesman Frank Fania.
Aurora police credit the break in the case to Colorado Bureau of Investigation lab specialists, who worked over the weekend to find a DNA match linking Washington to one of the rape cases. Washington's DNA was already in a state criminal database because he was required to provide a sample after a 2008 felony conviction for attempted burglary.
Aurora police learned of the DNA match after 5 p.m. Monday and mobilized its fugitive apprehension and gang intervention teams to track down the suspect.
"I think it goes without saying that if we didn't have his DNA on file, he'd still be running around the streets, probably doing the same thing again," Fania said.
