A Killeen woman is recovering after a stranger crawled into her bedroom window early Saturday morning and brutally attacked her.

Warning: Some of the images in the video below are graphic.

Marco Revuelta with our news partner, KWTX, spoke with Tawnie Lee about the ordeal. Lee said she was asleep in her bed when the man began beating her with a two-by-four. She struggled to fight back, and was saved when her 14-year-old son ran into the room with a knife, scaring the attacker away.

Police responded to a call about the attack around 5:50 AM Saturday, and the case remained under investigation Monday.

Lee is warning people, especially women, to keep their doors and windows locked, and to be sure their windows are completely covered.
