Liar, liar pants on fire. Miranda Barbour might claim to be the most prolific serial killer in American history, but there is hardly any evidence to prove she murdered countless people -- at least in Alaska. Authorities in The Last Frontier found the 19-year-old Pennsylvania woman seems to be lying about killing in their state.

Barbour told the Daily Item of Sunbury, Pa., from behind bars in a Pennsylvania prison that she was responsible for anywhere from 22 to 100 deaths over the past six years, from Alaska to North Carolina, but Alaska state troopers aren't buying it.

"At this time the Alaska state troopers are not aware of any information -- beyond Barbour's comments quoted in the press -- or evidence that would implicate Barbour with a homicide committed in Alaska," a statement from the agency said, as per CNN.

The agency has been in communication with Pennsylvania authorities regarding the so-called “Craigslist killer’s” "confession."

TMZ got in touch with officials in Palmer, Nome, Wasilla and Anchorage, all places in Alaska that Barbour named in her interview with Frank Scarcella from the Daily Item.

Here’s what each police department told the news site about the 19-year-old’s claim:

--Palmer: "We have no indication of any unsolved murders or missing persons cases involving her. We are a small town of 7,000 and have no unsolved crimes [during her lifetime]."

-- Nome: "At this point, I have no information to correlate to any claims that have been published in the media. If information is obtained during debrief by the agencies that are in contact with her that indicates there is something I should look at, then we will take the appropriate action."

-- Wasilla: "There is nothing unresolved or open that we are aware of that ties to her."

-- Anchorage: "There is nothing to connect her with any missing people or open cases. We are not aware of any cults or satanic groups within the area and at this time there is nothing to legitimize her claims."

It’s interesting Barbour claims to be responsible for so many murders, considering in the 2013 killing where she allegedly strangled and stabbed 42-year-old Troy LaFerrara, she said she and her husband Elytte (who is believed to have also participated in the murder) had trouble cleaning up his blood in her car. Also, police were led straight to Barbour since her number was the last one LaFerrara dialed on his phone.

Even the prosecutor who wants to convict Barbour, Northumberland County District Attorney Tony Rosini, doesn’t believe her other claims. "As of this date, there has been no verification of any of the information that has been subject of media coverage regarding prior acts of the defendant, Miranda Barbour," Rosini said in a statement, as per CNN.

"Any information regarding crimes committed in other jurisdictions has been or will be forwarded to the appropriate law enforcement agencies and the FBI for further investigation," he said.
