Detectives Briscoe and Curtis investigate the murder of Maureen Rankin who is found on a deserted tract of land. She died from a blow to the head though death was not instantaneous. The police believe she was the victim of a carjacking. They track the car and arrest the carjacker but a key piece of evidence is ruled inadmissible and his new assistant, Jamie Ross, is all for transferring the case to Federal jurisdiction when the death penalty will apply. The DA's office is batting zero after the judge in the case rules a second key piece of evidence inadmissible. It's left to McCoy to start playing hardball with the carjacker's fiancée if they want to have any hope of getting a conviction.

"Causa Mortis" is Latin for "Cause of Death." See more
The tape that was found is central to the plot, but it was not found in the tape recorder in the victim's purse. It was found days later, mashed into the mud at the crime scene. The recording goes right up until the time the victim is killed. When was it taken out of the tape recorder? The victim couldn't have done it. If the killer knew about it, he'd have taken the whole thing, not taken out the tape and thrown it away. See more

You know, before it happened... she wanted to quit. I talked her out of it.

Yeah, well... I could have kept walking past that bar.
