Who needs a defense lawyer when the media makes it for you

I couldn't believe that I read this:

Woman who lost son, 5, on murder charge over death of man

The reasons I'm surprised:

• her son died six years ago
• the man who died after being allegedly stabbed apparently had nothing to do with the death of her son
• no other person gets this sort of defense in the media

How is the fact that she lost her son relevant in any way to her arrest???
