Lubbock has been in the midst of quite a bit of dangerous and odd news lately. With the attempted terrorism and now a man burns his mother to death and tries to sexually assault a teacher in a school.

LUBBOCK - A Lubbock woman died Monday from the burns she sustained two weeks ago when authorities say her son doused her with flammable liquid and set her on fire before trying to sexually assault a teacher at knifepoint at a school, her husband said.

Bertha Bradley, 69, died at University Medical Center in Lubbock late Monday morning, Shirley Ray Bradley said. She sustained third-degree burns to more than half of her body on May 9.

Police say her son, George James Bradley, set her on fire in a Lubbock apartment before going to a nearby school where he tried to assault a teacher. The school superintendent helped free the teacher.

George Bradley remained jailed Monday on charges of attempted murder, aggravated assault and attempted sexual assault. Mark Snodgrass, his attorney, didn't immediately return phone call seeking comment.

Scott Morris, a Lubbock County assistant district attorney, said he could not comment when asked if the attempted murder charge against George Bradley would be upgraded to a murder charge. Family members said after the incident that they long feared George Bradley's violent temper but didn't know what sparked his alleged outburst, which happened on his daughter's 11th birthday.
