Williams said the brick that shattered her window was about twice the size of a regular brick.
About an hour later, Morrow police told Channel 2 the woman went inside the UEI vocational school on Southlake Parkway and threw more bricks before punching a staff member in the face.
Marks is accused in similar incidents in neighboring jurisdictions, Clayton County police said. Investigators suspect she has a mental illness, the news station reported.
She is still facing a host of criminal charges if caught. Clayton County police have obtained warrants for Marks’ arrest on charges of criminal trespass and battery of school personnel.
“Marks is not in custody, however the Clayton County Police Department and the Clayton County Sheriff’s Office are working diligently to capture Ms. Marks and prevent further property damage,” a police spokesman said.
Anyone with information about her whereabouts should contact police.
