BUTLER (KDKA) – A man charged with the rape and murder of his girlfriend’s 4-year-old son was trying to plan his escape from jail, authorities say.

Keith Jordan Lambing was charged last month in the death of Bentley Miller.

Lambing was locked up on March 22.

Assistant District Attorney Terri Schultz is prosecuting what many say is the worst case in decades for Butler County. She says Lambing allegedly tried to enlist his grandmother to help bust him out.

“The jail guards found a note in his pocket that basically explained that he was going to attempt to escape,” Schultz said. “He wanted someone to bring something to cut off his cuffs.”

The allegedly escape plan reportedly surfaced about two weeks ago.

The note allegedly said, in part, “…get Tyler to get a crew to open an[d] snip cuffs.”

Prior to the note, officials say the jail monitored a phone call to Lambing’s grandmother that said, “I gotta note I’m gonna show you, when you come in and stuff, alright?”

Authorities say they are concerned for Lambing’s safety.

“We’re concerned about Mr. Lambing’s safety. I know there have been, I’m sure threats. And we’re concerned about the public at large. We wanted to make sure that we have everyone safe,” Schultz said.

Lambing is now charged with attempted escape.

He was previously charged with criminal homicide, rape of a child, involuntary deviate sexual intercourse, aggravated assault and endangering the welfare of children.

There has been heightened security around him since he was arrested. He’s in protective custody.
