A Florida woman is accused stabbing her piano teacher moments before she was scheduled to have a lesson.
Police say Sharon Clahar, 41, attacked the music instructor with a knife outside of her North Miami Beach studio on Tuesday, NBC Miami reports.
Employees who work in the dentist's office next door to the studio, where Clahar was reportedly waiting, witnessed the ambush.
"You could see she was struggling... [The victim] was screaming and telling us to help and she was bleeding and call 911 and I was yelling," she told CBS Miami.
Police said Clahar stabbed the instructor several times in the upper arm.
The day after the incident, the injured piano teacher spoke out.
"I was crying out for her," Melinda Ferrari told WSVN. "First, I started fighting her off in silence. We were both silent, and I started calling for help, and then I remembered Jesus, and I said, 'Jesus. Jesus.' By the time I was stabbed once right here, at least a big one, she ran away."
Ferrari said that she had taught Clahar for several months and knew that the student had a history of mental illness. She said it was her understanding the Clahar recently had her medication changed. No motive has been released.
Clahar is charged with aggravated assault with a deadly weapon.
