Next day. Ryan walks into Delko's office. They both wear white coats and white latex gloves.

-Still, we can't visit her-Ryan says.-Why did you called me?

-I figured out something. Marks on top of roof ledge do match to Melissa's rifle. But they are scratches on back side of front roof ledge, wich also match to rifle's handle. This could only happen if rifle slipped to front, then down. It couldn't be enough to cause rifle to fire itself, but it could definetly change point of shooting. Rifle would be pointed about ten inches down. Here is 3D reconstruction.

They both walk to Delko's computer. Delco shows Ryan 3D reconstruction. It shows black figure standing on roof with rifle pointed like Delco described (killer) and green figure siting on the floor of prison toilet (Valera). Delco clicks and black figure fires. Bulliet shoots through glass on window of prison's toilet and shoots Valera in backs. She falls on the floor, face down. Ryan can barely look at it.

Delko looks at him.

-Are you OK?-he asks, woried.

-Yes-Ryan knods.

Delko looks at him for next few seconds, then gets back on work.

-So... If rifle would be pointed in straight direction...

He clicks few times and rifle changes in that position, then bulliet is fired. It shoots through glass on window of prison toilet, but doesn't shoots Valera. It comes through opened toilet doors, in hallway.

-Shooter never meant to shoot Valera-Ryan realises.

-No-Delko agrees.-He was targething someone or something in hallway. He must've slipped on oil stain on the roof. It was smudged, with yelow fibers were found inside. However, I checked and found out inmates from cell block E were going on lunch somewhen around the time of a shooting.

-Shooter was targeting inmate?

-Yes. Unfortunately, security camera in hallway was broken. But I get writen way as they stand in order during walk. Valera was wounded at about 2:34 pm. Target must have been from right. By that account, that would be...-he looks in file on desk near his computer-inmate number 5234, Carl Johnson, 34. He is on death row for murder of his wife, 27 year old Ling, Asian journalist, in 2009. He stabed her 20 times. He will be excecuted next week.

Horatio and Frank are in house of Ling's parents. It is big suburbian house. Her father, Lou, is siting on coutch in living room. He is Asian, in early 50's, with short black hair and black eyes, about 5'9 tall, average weight, wearing blue shirt, black pants and black shoes. Her mother, Wendy, is siting in armchair near coutch. She is Asian, in early 50's, about 5'4 tall, average weight, with long black hair and black eyes, wearing white shirt, blue jeans and white woolen slippers.

-Where were you todey about 2 pm?

-We were together, here. Only two of us-Lou answers.

-We have nothing to do with this-Wendy says.

-Why would we try to shoot him?-Lou asks.-He will be excecuted next week.

-But he had parole hearing today-Frank says.

-Wich was denied-Lou says.

-But you couldn't know that-Horatio says.

-I'm afraid I need to ask you to leave-Lou says.

-That's last thing you should be afraid of in this moment-Horatio says, before he and Frank walk off.
