EMERSON HILL — A woman threatened to blow up a high school after she found out her daughter failed a Regents exam, a law enforcement source said.

On Tuesday, a guidance counselor who works at Susan Wagner High School on Staten Island called Karen Shearon, 48, around 9 a.m. and said her daughter had failed a Regents exam, the source said.

When Shearon heard the news, she told the counselor "I am going to blow up the school," according to court papers.

Shearon was arrested on Wednesday and charged with aggravated harassment, according to the Staten Island District Attorney's office.

She was expected to be arraigned on Friday.

UPDATE: On March 29, 2016, Shearon's lawyer, Todd Spodek, said that his client has rejected all plea offers from the district attorney and the case will go to trial on May 2016.

"This is a case in which every piece of evidence goes against the charges," Spodek said.

"The complainant was not scared and not one precaution was taken by the school, let alone an evacuation, after a so called bomb threat. I have every confidence that Ms. Shearon will prevail at trial."

Other notable crimes in Staten Island include:
