On April 4, 2003, 25-year-old Kristi Mills awoke to the unimaginable: a masked intruder standing in her doorway.
"I was in shock," Mills said. "Absolute shock. I looked at the door and saw the light there, and something just didn't seem right. And that's when I saw him.
"The next thing I remember is he was on top of me in the bed," she said. Mills said the intruder told her he was there to burglarize her, and that he didn't want to hurt her, but if she made noise, he would shoot.
Wearing a ski mask and gloves, he seemed oddly calm and methodical as he bound her with zip ties and duct tape, she said.
"He actually taped all the way around my head so that I wouldn't be able to open my mouth at all. Put tape over my eyes."
Then he slipped a pillowcase over her head. "He seemed very assertive when he talked and not like somebody who's, you know, panicking. He seemed like he knew what he was doing," Mills said.
The man sexually assaulted Mills for 45 minutes.
Then, still blindfolded, he forced her into the bathroom where she heard water running. "I started to panic and I thought he was going to shoot me in the bathtub," she said. "Just over a month from my 26th birthday, and I was going to die."
Mills was forced to take a long bath and told to wash carefully, while her rapist calmly walked about her apartment cleaning up after himself.
As quickly as he had arrived, he was gone, taking with him all the evidence, including the bed sheets.
She was so upset and scared that when she got out of the bathtub, removed the pillowcase, and ripped the tape from off her eyes, she "actually ripped hunks of hair out." She then called 911.
Two years later, the rapist found his fourth victim, 28-year-old restaurant manager Sarah Kalmes-Gliege, who also awoke to someone coming into her room in the middle of the night. She was just six weeks away from her wedding.
"It was gun to my head, knife to my throat," said Kalmes-Gliege.
He made it clear he had been stalking her, and he threatened her loved ones. "He knew everything about me," she said. "What my sister looks like to what car my husband drove, my work schedule. He knew where I worked out. Pretty much everything."
Kalmes-Gliege had brushed off an attempted break-in a couple of months earlier. "I didn't take that seriously," she said.
The intruder sexually assaulted and attacked Sarah for almost three hours. As with Mills, he was careful. He bound her hands and covered her head with a pillowcase.
"The majority of the assault was spent just humiliating and demeaning and terrorizing me. I mean, it wasn't at all about anything to do with sex. Just devastation is what, how I felt."
Before leaving, as he had with Mills and his other victims, the attacker forced Kalmes-Gliege into the bathroom for a long soak to wash away the evidence.
"All I could think about was, 'I can't have someone call my family, my fiancé, my parents, my siblings and tell them that I have been killed six weeks before I get married,'" she said.
He left her alone, shaking in her tub and waiting hours until sunrise to flee.
Although she considered telling no one, she thought, "If I don't tell the police, this person is going to rape yet another person." So she called the cops.
