Grandma charged in bomb threat

A 51-year-old woman who was barred from visiting her grandchildren at their school is facing a third-degree felony charge after a bomb threat was called in to the NortGrheast Side campus.

Velma Gladys Brewster was charged with making terroristic threats to Windcrest Elementary School at 465 Faircrest. She was arrested Thursday and released from jail after posting bail. Bond for the third-degree felony charge was set at $10,000.

When staff arrived at school on Thursday, they heard a voicemail message warning of a bomb threat, according to an affidavit for arrest warrant.

Administrators recognized the female voice that left the message – which had been left Wednesday night – as Brewster's, according to an affidavit for arrest warrant.

The trouble with Brewster began the day before, when the school's principal issued a trespass warning after the woman attempted to visit her granddaughters without permission from her daughter, police said. According to the warrant, Brewster was asked to leave the campus after causing a disturbance about 11 a.m. Wednesday.

The threatening message was left at 6:44 p.m. Wednesday, police said, but school employees did not check the voicemail system until about 7 a.m. Thursday.

The threat prompted the school to evacuate up to 678 students and 85 faculty employees, while the Windcrest and North East Independent School District police departments investigated.

The San Antonio Police Department's bomb squad also assisted in a search for explosives, but no suspicious devices were found at the scene.
