They say she told a friend that her marriage was in trouble and that she was thinking about moving the kids to Washington, D.C.,

They also say that Brian's mother hired a private investigator to follow her around to see if she was having an affair.

Another theory is that prosecutors say Brian was the beneficiary of her $2.7 million life insurance policy, and he owed hundreds of thousands of dollars in his federal art fraud case.

So was money a motive?

His defense says he was already paying back the money that he owed in that case.

And as far as the alleged infidelity, they say Brian didn't know anything about that.

That's right.

So Brian Walsh was stabbed in jail this past September, and he recovered.

But following that attack, his attorneys were concerned that he may not be mentally or emotionally capable of participating in his own defense.

So they stopped everything, and he spent about 40 days undergoing psych evaluation and was only just last week declared competent to stand trial.

And so that led us to this week.

Tell me what happened there.

It felt like it was all steam ahead.

There was a hearing on Monday.

The attorneys were sparring over opening statements and about what the jury could hear.

Reporters noticed that Brian's mom was in the courtroom.

She even blew a kiss to her son.

The very next day, though, that Tuesday, everything changed.

Right.

Jury selection was supposed to start.
