"It's a very relevant question... did you have sex with her, yes or no?" the investigator continues, but Mitchell again goes off on a tangent.
"You say you want to know the truth but the truth will set you free, it will set all men free," he says.
When Parks presses Mitchell for details of what happened that night Smart disappeared from her bedroom, Mitchell refuses to answer.
"Did you take this girl out of her house at knife-point, yes or no?" Parks asks.
"I'm not going to answer that question," Mitchell says.
"And why not?" Parks asks.
When the detectives try again to get Mitchell to open up, he responds with a Biblical reference, comparing himself to Peter.
"I don't expect that you are going to get out of custody until the day you die ... OK," Parks says. "Your future depends on this interview ... right here, right now. You're not taking this seriously."
"Do you remember that Peter was in prison and an angel came and the guards opened the doors and let him out," Mitchell says.
"Isaiah, no angel is going to let you out of this room," the detective said. "There's nobody coming for you."
