Hear the 9-1-1 Calls Two College Students Made When a Convicted Rapist Allegedly Held Their Roommates at Knife Point

Authorities in Washington have released the 911 recordings two female University of Washington students made when a convicted rapist allegedly held their six female roommates hostage with a knife during a home invasion -- two months after he got out of prison.

Robert Hitt allegedly broke into the women's home around 3:30 a.m. March 5. That's when police say he held the six women at knife point, not knowing there were two other women in the home, hiding and calling 911.

According to Seattle ABC affiliate KOMO-TV, the first call came from a downstairs bedroom, with the caller whispering there was someone in her home and that she'd heard her roommate scream.

"I can hear her still. It sounds like she's alright, but it sounds like he's harassing her so I'm scared for her," the caller said.

Another call came in moments later, this time from upstairs. Neither woman said they knew who the man was.

While on the phone with the 911 dispatcher, one of the women said she heard him threatening the roommates downstairs, and heard the sound of ripping duct tape.

"[He said] I'll stab you," she said. "He's taping her. He's taping her somewhere. I'm worried he's going to come find me."

Police arrived within minutes and arrested Hitt, KOMO reported. None of the women were physically injured, though one woman was allegedly forced to remove her clothes.

Hitt was charged with nine felonies, including kidnapping and robbery, and faces a life sentence if convicted.

According to ABC News, Hitt had just been released from prison in January after serving a 10-year sentence for first-degree rape.
