Truly bizarre:

A painter working at David Letterman’s Montana ranch was charged Thursday with plotting to kidnap the talk-show host’s toddler son and nanny and hold them for $5 million ransom.

Kelly A. Frank, 43, was being held on a felony charge of solicitation, among others.

Montana Department of Corrections spokeswoman Sally Hilander said the plot was uncovered when someone Frank had approached about the plan informed local police.

They’re throwing the book at this guy:

In addition to the solicitation charge, Frank also is charged with felony theft for allegedly overcharging Letterman for painting, and a misdemeanor charge of obstruction for lying to an investigator who first contacted him about the alleged plot. [emphasis mine]

Mind you, this isn’t the first time nutjobs have gone after Dave:

For years, Letterman was targeted by a stalker who called herself “Mrs. David Letterman” and broke into his Connecticut house at least seven times.

Margaret Ray eventually pleaded guilty to breaking and entering. Diagnosed with schizophrenia, she served 10 months in prison and 14 months in a mental institution. In 1998, she committed suicide at age 46 by kneeling in front of a train.

As Steven Taylor says, this is insane.
