The 26-year-old Philadelphia man who created Facebook pages titled "Kill Mitt Romney" and "Kill Seth Williams" was being sought Monday for criminal solicitation to commit murder and other offenses, authorities said.

Joshua Scott Albert first stirred anger last month with a Facebook page titled "I Support Chancier McFarland & Rafael Jones," referring to the men charged with the murder of Officer Moses Walker Jr.

Albert, who won brief notoriety as the man behind an anonymous blog about Philadelphia's restaurant industry, gained the attention of the Secret Service, who investigated him for his "Kill Mitt Romney" page.

Tasha Jamerson, spokeswoman for District Attorney Seth Williams, said Monday that prosecutors had approved three counts of criminal solicitation to commit murder, three counts of terroristic threats, and three counts of harassment against Albert.

An arrest warrant for Albert has been approved, but his whereabouts were not known Monday night.

Last week on his blog, Staph Meal, Albert addressed the controversy in a post titled "I'd Say Being Investigated By The Secret Service Is A Pretty Good Time To Retire."

He marveled at how much trouble he had caused. "With that being said I am finished. For real this time," Albert wrote.

After the criminal charges hit the news Monday, Albert took to his Twitter account and posted: "This is a sad day for American Civil liberties."
