Police in the southern province of Binh Phuoc Thursday arrested a woman for allegedly killing her two young sons and throwing them into a well in her garden the day before.

They said they are waiting for the results of a mental evaluation of Dieu Thi Chanh, 26, of Dang District who neighbors claimed was mentally ill. She has no documents claiming she has mental problems.

Chanh told the police she slit the throat of her elder son, aged four, and strangled the younger one, who was two.

She threw both their bodies into a deep well.

Her husband discovered them after coming back home from work hours later.

The investigation continues.
