Williams-Major was first arrested last April along with six other people who were inmates, prosecutors said. Investigators discovered the seven suspects had conducted an EDD fraud scheme that gained them more that $250,000.

However, in the following investigation, it was discovered through contents on Williams-Major’s cell phone that the alleged unemployment fraud scheme was more than 10 times larger that previously thought, prosecutors said.
