A Texas mother was arrested this week on allegations she purchased ammunition and tactical gear for her son, who authorities said was planning "mass targeted violence" at a San Antonio school, according to an affidavit obtained by CBS News.

Ashley Pardo, 33, was arrested Monday on one count of aiding in the commission of terrorism after tactical gear and ammunition were found at her home, which authorities said she purchased for her son in exchange for babysitting his younger siblings, according to the arrest affidavit issued by Bexar County Magistrate Court. 

Pardo "intentionally and knowingly aided" her son, San Antonio police wrote in the affidavit.
