How could someone possibly do this to a sweet little old lady?! According to police, it was two teens that murdered this Pocatello grandma.

18-year-old Dustin Alfaro and his 17-year-old unnamed accomplice stand accused of killing 87-year-old Arlyne Koehler of Pocatello.

According to this CBS article, Koehler was stabbed to death and there is evidence that she fought for her life so hard that she injured her attacker.

The pair are from Marysville in Yuba County, California and it is unknown what their relation was to this poor old woman or what they were doing in Idaho.

Both Alfaro and his accomplice are expected to be extradited back to Idaho in the coming days.

I will never understand someone being this heartless. Hurting an innocent old woman is almost as bad as hurting a child. How you could stab an old woman to death is beyond my comprehension.

So far, if found guilty, it is unknown what this pair will face. I'm assuming it is quite possible that they could spend the rest of their lives in prison.

When things like this happen, I am always left questioning "why?" What did they want from this sweet old lady? Why were they willing to kill her?

Nobody should ever have to face the last moments of their life the way that Arlyne did. Our thoughts and prayers are with her family and everyone who loved her.
