An adult son is accused of sexually assaulting his own a mother last month in their home in South Memphis.

The suspect was arrested over the weekend.

We can't show the 37-year-old suspect's face or even give you his name because we would also be identifying the alleged victim his 57-year-old mother.

According to court papers, last month the suspect asked his mother to come into his bedroom and hold a table while he changed a light bulb in the ceiling, but instead police say he grabbed his mother from behind and raped her.

"It's awful," said Annette Griffin.

Annette Grffin, who lives in the neighborhood, didn't know the woman and hadn't heard about the crime.

She's is glad the son is now behind bars, but not completely surprised by the violence.

"They do it all the time," said Griffin.
