She said she saw Brady push her mother, causing her to fall, and as she fell, Brady was said to have stood over her in an attempt to hit her.The victim said she was scared, saying whenever Brady drinks alcohol, he blacks out and begins to act irrational and violent. Despite being told she could apply for a restraining order, the victim said she didn’t wish to get one against her grandson.Police say it took three officers to help Brady walk since he was so intoxicated and that a prisoner van had to be called to the scene to bring him back to the station because they couldn’t get him into a cruiser.
