Bryan Roche confesses during police interview

CEDAR RAPIDS - Bryan Roche said during a police interview that he thought the 20-year-old woman he sexually assaulted and stabbed in the neck and stomach was going to die April 21, 2013. 

Cedar Rapids police Investigator Douglas Larison asked him when, during the chain of events, did he stab the woman and why.

Roche, crying, said he stabbed her after 'I raped her.” He stabbed her because she was screaming and he "wanted her to be quiet."

'I don't know what I was thinking at the time,” Roche told Larison.

The videotape was the last piece of evidence played by the prosecution Wednesday before it rested. Roche, 22, of Marion, didn't take the stand and the defense didn't put on any witnesses.

Roche is charged with first-degree kidnapping, first-degree sexual abuse, attempted murder and willful injury causing serious injury. He is accused of holding the 20-year-old woman against her will and repeatedly sexually assaulting her and stabbing her twice in her home April 21, 2013. Doctors testified Tuesday the victim's wounds were life-threatening.

Roche's version of what happened that day is similar to the victim's testimony Tuesday.

Larison testified Wednesday that Roche for the first five hours of the interview denied he harmed the victim. Roche initially said he went over to see the woman that day but she was with another man. He only saw the woman for 15 minutes and then left and bought some pop at Wal-Mart.

Larison said they checked out his story about going to Wal-Mart and buying pop but it was an hour or so later than he claimed. Police had his debit card transaction of the purchase.

In that last hour of the interview played for the jurors, Roche at first said he didn't want to remember and didn't want to tell them. He said it wasn't going to happen again because he will be locked up.

Larison keeps coaxing him to do 'something right” and tell them what happened.

Roche said the woman didn't do anything to provoke his actions. He admits to tying her up with red tape, sexually assaulting her and stabbing her in the neck and 'in front,” but not sure where. He also admits to telling her he had to kill her so she couldn't send him to jail.

Roche said more than once he finally left the victim's apartment because he thought she was going to die. Aaron Hamrock, one of Roche's attorneys, on cross examination asked Larison if Roche appeared to be emotional and remorseful.

'Yes, he was emotional,” Larison said. 'I couldn't say if he was remorseful.”

Hamrock, in an attempt to show Roche's intent, asked if Roche said he stabbed her because he wanted her to be quiet.

Larison agreed.

Linn County Attorney Jerry Vander Sanden on redirect asked if Roche admitted to stabbing the victim twice.

Larison said yes.

Vander Sanden asked if he remembered what Roche said about the stabbing.

Roche said he didn't think she would survive, Larison said.

In other testimony Wednesday, Cedar Rapids police crime scene investigators identified evidence collected at the scene.

Investigator Ron Johnson said there were two latent fingerprints found on a gray plastic bag and red tape that matched Roche. The plastic bag contained a used condom, knives and red tape, which Roche told police he tossed in a dumpster after the crime. The red tape was used to tie up the victim, according to previous testimony.
