Police sources tell KDKA television in Pittsburgh that 20-year-old John McCain campaign volunteer Ashley Todd has admitted to lying to them about being mugged and attacked by a man who carved a "B" into her cheek after seeing a McCain bumper sticker on her car. Todd is expected to face charges for the false report, according to KDKA.
Below is FOXNews.com's earlier reporting on police questions about the attack:
PITTSBURGH -- Police are questioning several "inconsistencies" in statements made by a woman who claims to be a John McCain volunteer and says she was robbed at knifepoint by an attacker who cut a "B" into her face after noticing a McCain bumper sticker on her car.
Pittsburgh police spokeswoman Diane Richard would not say whether police doubt the story alleged by Ashley Todd, 20, but told FOX News that no evidence yet indicates Todd was at the Citizens Bank ATM in Bloomfield, where she claims the assault took place. Richard said Todd is staying with a male friend who lives down the street from the ATM.
A woman named Liz who answered the door at the residence where Todd arrived after her alleged attack told FOXNews.com that her roommate is friend's with Todd, and he told Liz not to discuss any details about the incident. A Ford Taurus with a Texas license plate and a McCain-Palin sticker was parked outside.
Todd, who reportedly hails from College Station, Texas, told police that on Wednesday night at 9 p.m. ET, a 6'4" black male in dark jeans and a black tank top held her up at the ATM. According to a police report, Todd said the robber put a knife to her neck and demanded money. She said she gave him $60.
Todd also told police that the robber then noticed the McCain bumper sticker on her car, punched her in the back of the head, knocked her down, and continued to punch and kick her while threatening to teach her a lesson.
"You are going to be a Barack supporter," she recalled the robber saying before he sat on her chest, pinning both her hands down with his knees and scratched the letter "B" on the right side of her face using what she believed to be a very dull knife. Then the robber fled, she said in the police report.
Richard said Todd later added to her tale, saying she was groped by the robber and lost consciousness during the assault. Neither of those details was in the original report.
Richard said after a second interview, Todd also was not as definitive about the assault or the motives behind it, nor could she say for certain whether the robber took $60 from her as she initially reported but maintains is missing.
Todd took a polygraph test late Thursday or early Friday after police heard the inconsistencies, Richard said.
'There were major changes in her story" before and after the polygraph test, Richard said. As for the wound on her cheek, "it's very shallow, it's more of a scratch."
Richard said the police department continues to investigate the report and takes it "very seriously." Police are reviewing surveillance footage and searching for witnesses. She said Todd is still considered a "victim" of an assault, and she noted that victims often tend to forget details of situations that happen to them under duress.
The area at Liberty Avenue and Pearl Street where the attack allegedly took place is heavily traveled in the daytime, full of traffic, pedestrians, restaurants and stores. On Friday, Pittsburgh detectives were canvassing the area looking for witnesses. One detective told FOXNews.com that they had talked to a few people but have "nothing solid."
Doug Graham, a neighbor of the residence where Todd's friend lives, told FOXNews.com it's unlikely an assault at the bank would go unnoticed.
"There ain't no way nobody saw that," Graham, whose home -- where he has lived for a decade -- sports a Barack Obama sign. "It's always hopping up there. Something fishy, I knew the first second I saw (her story. Something fishy."
Ethan Eilon, executive director of the College Republicans National Committee, told FOX News Todd was volunteering as a field representative through his organization and that she had taken a year off from her studies at Blinn College to work on the campaign.
Eilon, who spoke with Todd following the attack, said that after she worked at the phone bank at the University of Pittsburgh, she went in search of a hotel and stopped by the ATM in the Bloomfield neighborhood. He said she was walking up to the ATM when she was attacked from behind and the mugger asked for her money. She gave him about $60 and he let her go.
According to Eilon, Todd tried to run for her car and he chased her down, once they got towards the car, he saw the McCain bumper sticker and became enraged yelling epithets and said, "You are one of those McCain people." He then began to beat her and stood over her and carved the "B" into her cheek.
Todd received a call from the Republican presidential nominee and has spoken with her family. Barack Obama's local campaign team also issued well-wishes to the Texas resident.
Police say Todd initially refused medical attention, though FOX News was later told she went to the hospital Thursday.
Several blogs and message boards, including on one of Todd's own Web pages, are skeptical at best about Todd's story, arguing the details are fishy.
"There's just a lot of unanswered questions," one source familiar with the investigation told FOXNews.com. "The story just sounds very bizarre."
