AURORA, Colo. -- Home is often a place of safety, but home recently became a crime scene for three women at two Aurora apartment complexes.
Aurora police are warning the public about what may be a serial rapist.
Within eight days, an unidentified man sexually assaulted two women and tried sexually assaulting a third.
It happened at Hearthstone at City Center and next door, at The Colonnade, in the 800 and 900 blocks of S. Chambers Rd.
On Friday night, Aurora Police went door-to-door -- armed with information -- warning neighbors about a man whose broken into three apartments, all within one block of each other, in eight days.
He sexually assaulted the first woman early Thanksgiving morning. Then, attacked a second woman six days later on Nov. 28. The man struck again Friday morning on Nov. 30.
"Early this morning, we had a third incident. Thank goodness the victim in this one, the third one, was awakened by the suspect. She start screaming. He took off running," said Aurora Police Sgt. Frank Fania.
Each attack happens as the women slept, which makes it more difficult for police to identify a suspect.
"These happened in dark bedrooms. We haven't been able to compose a sketch because we don't have an accurate enough description," said Fania.
But they do know he broke into ground-floor apartments with locked windows and sliding glass doors. He also had a weapon in, at least, one assault.
"So you're looking at three? That's a lot. I would definitely say it's someone watching this area, or watching the women, or definitely knows the area to feel he's safe enough to do this," says Hearthstone resident Carla Vaughn.
Neighbors say the string of attacks is scary.
But they also question why they're just learning about them now.
"I think they were trying to hide it." says one young man, whom didn't want to be identified.
His unidentified girlfriend says, "The apartment complex, the police could have done something sooner. Somebody could have said something at least so we can be on the lookout."
And that they are--heightening their awareness and security.
"We keep a metal rack right next to our headboard. And I have mace. And my husband is a Marine," says another Hearthstone resident, who didn't want to give her name.
Police ask people to make sure they lock their windows and doors--and put a dowel or stick inside the window and doors tracks.
Keep your porch light and any other extra lights on.
And report suspicious activity or people.
The suspect is described as either a Hispanic or light-skinned black man.
He's tall and thin--about 6'3", 180 lbs., 30- to 35-years-old.
One victim says he had shoulder-length corn-row hair, a mustache and goatee.
