Today's story is both heartbreaking and deeply troubling.

And after we go over everything you need to know,

we're going to have Dr. John Matthias,

a criminal psychologist, come on to help us understand.

So this story is about a woman who had already survived

one of history's greatest atrocities, the Holocaust,

We're talking about the murder of 89-year-old Nina Krastoff, a Holocaust survivor, originally

from Ukraine, who was brutally beaten to death inside a Brooklyn

nursing home this past September.

Police say her roommate, a 95-year-old woman who had only just been admitted to the facility,

is responsible.

There is now newly released information about Nina's life, the night of the attack,

the charges now facing the suspect, and many questions being raised about nursing home oversight

and the care of dementia patients. And before this tragedy, Nina Krafstoff had already lived

through more than most of us can imagine. Born in Ukraine, she was just five

years old when she and her family were forced into a ghetto during World War II. Most of her

large family didn't survive. Nina did in part because her 16-year-old sister caught the eye of the

ghetto manager and was able to keep moving their names to the bottom of the deportation list.

And every time new Jewish people arrived, her family's names were pushed down.

Those at the top were sent to concentration camps.
