Cold Case (2003)

Thrill Kill - S5-E1

Factual error: When Dylan gets out of jail, a palm tree can be seen in the background behind him. This reveals that the scene was filmed in Los Angeles, not Philadelphia.

Devil Music - S5-E4

Character mistake: When they pulled the bullet out of the wall of the Five and Dime, Danny says that it was either a .40 or .45 caliber. The .40 caliber was not produced until 1990, 37 years after the date the crime took place. (00:30:00 - 00:35:00)

Thick as Thieves - S5-E5

Factual error: Look at the area by the door when we see Margot and Spencer in the hotel room in 1989. The light switch is a flat "Decora" switch, and above the door handle is a black box that houses electronics for a "card key" system. The light switch was not introduced until the 1990s, and while the card key system was introduced in 1985, only very expensive hotels afforded the conversion costs - and the hotel they're at isn't exactly the Hilton.

Sabotage - S5-E12

Factual error: When Rush and Miller pull up to the vacant lot, the Los Angeles skyline is visible in the background. The series is set in Philadelphia. (00:21:54)

Glory Days - S6-E1

Factual error: The episode opens in a locker room with the players singing "Taking Care of Business". However, it is supposed to be October 1973 and that song was released in December 1973.
