S5E3 Blood Trail / 50G Murder

Title: Blood Trail / 50G Murder Plot: In Memphis, Tennessee, a woman is viciously attacked and abandoned in the street. A witness steps up with the van's license plate that sped away from the scene, prompting the homicide team to devise clever strategies to draw the suspect out. Meanwhile, in Dallas, Texas, Detective Rick Duggan delves into the shooting of an elderly man, discovered dead in his dental office. With minimal leads, the case takes a turn when a woman arrives at the precinct, offering information that appears almost too incredible to believe.
