Harley was sentenced to 15 to 30 years in state prison.
Ashley Hackett was attacked as she was walking to her home on South 9th Street last November.
"It's definitely a weight off my back, now," Hackett said.
Authorities say Harley approached Hackett from behind and struck her in the face with a knife, causing a large cut.
Harley then grabbed Hackett's purse and fled.
The purse was later found in a small alley at 800 Kenilworth Street.
Hackett needed more than 100 stitches to close the wound.
"I look over my shoulder more than anybody should. It's unfortunate that those values were taken from you in such an inhuman way," Hackett said.
Hackett says her trust has been violated: her trust in community and her trust in humanity.
She was not in court Tuesday, but an impact statement was read before Harley was sentenced.
"He showed no remorse, didn't want to apologize, didn't say he was sorry. It was made note on his record," Hackett said.
Her scar is now barely noticeable.
Investigators and those who know her say she is a strong young woman and today is yet another step in her healing process.
"It's been a rollercoaster, ups and downs and it changes. You heal every day. The scar heals every day. The pain changes every day. Emotionally, it changes every day with the circumstances that I'm in," Hackett said.
Hackett says she was prepared to go to trial, but this guilty plea was the best possible outcome.
