A Deadly Dose

When Susan, a wife and mother of two, dies from ingesting antifreeze and oxycodone, it's ruled a suicide; her parents suspect that Susan's husband, Brent, is behind it.

When Brent's drug use is exposed, witnesses defend him, including his assistant and his daughter, who both claim Susan had a dark side others didn't know about; phone records reveal more of Brent's lies; the team decides to put him under oath.

In the wake of Brent's fiery deposition, new witnesses emerge that paint Susan as suicidal; Tony's team soon believes that the missing family computer holds the key to the case.
