A Woman Beats Foster Son To Death For Stealing N50 To Buy Gala

A woman known as Iya Anu, was alleged to have  beaten her foster son, Seubow, (her husband's nephew) to death for allegedly stealing N50.(Fifty Naira)
 Iya Anu, was alleged to have previously physically and mentally abused/tortured  Seubow  whenever he misbehaved like other of her four children. 
On Saturday the 16-year-old Seubow misplaced a N1, 000 note given to him for an errand, as a result, Iya Anu starved the teenager throughout Saturday. When Seubow could no longer bear the hunger, he sneaked out of the house at night to buy Gala.
When  Iya Anu knew about it, she was so irked that he accused him of stealing her N50 and beat the teenager with suspected hot object from Saturday night till 9 am following day .

“She battered him till he gave up the ghost about noon.  When she realized that the boy had lost consciousness, she cried for help but it was already late.  At a point, she wanted to run away but she was promptly rounded up.”  a co resident said
 It was said that sometimes in the month of June this year, Isheri-Oshun Police Division   had questioned  Iya Anu, for battery the boy

“Also, she has in the name of discipline used a knife to injure her first daughter, Anu, on her shoulders over issues bordering on misdemeanor.
Alexander Akinnurun, the Proprietor of Alex Group of Schools, Ijegun, the school Seubow attended before his death, described her as a violent woman
Iya Anu is a serial divorcee and is at present with her third husband.
 She has been arrested by the police at Isheri Oshun.
It is of a bit wonder that her husband could not do anything to avert this ugly situation.
Iya Anu probably needs medical attention.
What do you think should be done to her?
