Is nothing sacred? The question is being raised in wake of a disturbing discovery in a Pennsylvania cemetery: The gravestone of Hillary Rodham Clinton's father has been found toppled over, NBC News is reporting.

According to NBC, police say vandals may be responsible for upending the gravestone of Hugh Rodham in the Washburn Street Cemetery in Scranton.

Scranton police Chief Carl Graziano tells The Times-Tribune someone at the cemetery reported the stone was tipped over Tuesday. This comes two days after Clinton announced she's running for president.

The chief tells the newspaper that it's unknown how it tipped over but, added that he's "not sure how else it would have fallen over."

Background: Rodham grew up in Scranton. He owned a small textiles business in Chicago. He died in Little Rock, Arkansas, in 1993 at age 82.
