The 28-year-old woman accused of pointing a loaded gun at a private girls’ school official has a history of harassing school children, Charleston police say.

Officers on Monday recognized Alice Boland, of Francis Marion Circle in Beaufort, from an incident that occurred two years ago at Ashley Hall in Charleston.

In that incident, police said Boland was harassing school children and acting suspicious.

She returned to the school Monday afternoon, this time armed with a loaded .22-caliber pistol with eight bullets in its magazine, police said.

As parents were picking up their children about 3:20 p.m., a woman approached the school “exhibiting erratic behavior,” said Jill Muti, head of the school.

A police report said Boland was pacing back and forth and mumbling to herself in the area where students gather for car pool pick-up.

The school was placed on lockdown and a faculty member approached the woman. The woman drew a gun from her bag. Faculty members tried to lead her away from the school. She stayed on the sidewalk and never entered the campus. The faculty members went back inside to call police.

Officers told the woman to drop the gun and get on the ground, according to a report. Boland responded by asking police if they wanted her to do some push-ups, the report states.

At a bond hearing today, Boland said she was making a political statement against racist feminism. She also said she didn’t understand the attempted murder charge because the gun didn’t fire when she pulled trigger because it was defective. Boland’s bail was set at $900,000.

Boland sought treatment from a psychologist’s office near the school in the past, according to police. Officers said they found her vehicle parked near that office on Monday.

Officials searched the school’s records, but could not find any connection between Boland and Ashley Hall, Muti said today in a statement to parents and faculty.

“To the best of our knowledge, she was not targeting any specific person. All of our current information points towards this being a random incident,” Muti said in the statement.

The incident was not Boland’s first arrest.

In August of 2010, the Beaufort County Sheriff’s Office charged Boland with third-degree assault and battery, State Law Enforcement Division records show.

Charleston police on Monday charged her with attempted murder, two counts of pointing a firearm, unlawful carrying of a firearm and possession of a firearm during the commission of a violent crime, Charleston police spokesman Charles Francis said.

Ashley Hall will support prosecution on all charges, according to a statement from school officials.
