A jailhouse neighbor of Nikolas Cruz said the Florida school shooter spent his days pacing and staring vacantly in his cell.

“He was just lost in his mind,” the inmate, Andrew Bryant, told local station WFTS Tampa Bay.

“I don’t think he was looking at anyone, just laying down looking at the roof,” Bryant claimed.

Still, Cruz, who at the time was kept in the infirmary at the Broward County Jail, didn’t strike him as nuts.

“I just hope he doesn’t plead insanity or he gets off or anything, because, in my opinion, I don’t think he’s crazy and [he] deserves everything coming to him.”

A deputy at the jail is required to check on Cruz every 15 minutes, and record observations.

Logs of these observations, released by the Broward County Sheriff’s Office, indicate that Cruz makes little eye contact and often sits with a blank stare, as if in thought.

Cruz is cooperative and coherent — and one night, asked for a Bible to read, the deputies observing him wrote.

He has met with his attorney, psychologists, investigators, his brother, and a family friend.

With his attorney, he appeared “responsive to interview, shaking his head, nodding and agreeing, forward and engaging in the conversation,” the notes say.

Cruz is currently housed on another floor of the jail, and is being kept away from other inmates.
