Maybe Jennifer McCabe should have worn her little cross again to court.

Perhaps, though, she knew going in that she’d be embarrassed that her ostentatious show of faux religiosity was about to be undercut by the breathtaking years-long string of lies she was about to get called out upon on cross-examination.

For instance, when FBI agents arrived at her house to interview her about the murder of John O’Keefe, they asked her if she was Jennifer McCabe.

“I’m not Jennifer McCabe,” answered Jennifer McCabe.

An auspicious beginning indeed to a relationship with the G-men!

Finally, inside her house, the feds called her and Jen McCabe finally admitted she was Jen McCabe. The G-men came in and mentioned something to her, as defense attorney Alan Jackson reminded her.

“They mentioned to you that it is a crime to lie to them on a material issue during an interview.”

“Yes.”

So then Jen McCabe said she’d need 10 minutes before she could speak to them. She took the time and when she returned they asked her if she’d called anyone in those 10 minutes.

She lied again. She told them she’d only called her husband. But she had an excuse for her lying.

“I’d just dropped my kids off to school,” she stammered. “I hadn’t brushed my teeth.”

Her teeth? Surely she meant to say, her tooth.

Doesn’t she understand, despite her dental issues, that when under oath or speaking to law enforcement, she is compelled to tell the tooth, the whole tooth and nothing but the tooth.

Er, truth.

On the cross, Alan Jackson drilled down on her second lie to the FBI, when asked if she’d spoken to anyone besides her husband.

“Your answer was no?”

“Correct,” said Jennifer McCabe.

“And that was a lie?”

“It wasn’t a lie, no.”

But in fact, after the feds arrived, Jen McCabe panicked.
