Cold Case

We find out that Ray and Lilly have known each other since childhood.

This is one of the few episodes in which the victim's 'ghost' doesn't appear at the end, probably because of her infant age.

Goof: When Iris died in April 1982, they said she was six months old. However, in the end of the episode when Lilly visits her grave, the headstone reads 1982-1982. If Iris was 6 months old when she died, she should have been born in (late) 1981.

Iris Felice died on April 19, 1982.

Nitpick: There are some discrepancies with the timing of John Donovan's death. The detectives state that he disappeared on a Sunday. Yet later they find out that Donovan disappeared and died on April 28, 1948. However, this date falls on a Wednesday.

Dana Taylor disappeared and died on October 13, 2004.

From Dana's missing persons file, we can see that she was born on April 16, 1976. Yet when Det. Jeffries pulls her file from the case box, he states Dana was thirty. She would have turned 30 in 2006, but when she went missing, she was 28.

We learn the exact age Lilly was when her father left: six.

We find out that, like Lt. Stillman, Jeffries is a Vietnam War veteran.

Pay attention to Scotty's choice of words when his brother teases him about not visiting them more often: "I can't visit my own brother without being abused?"

Nitpick: The medal shown is given a vague name (Ribbon of Valor). However, it isn't any medal currently issued in the US military, although it somewhat resembles a Distinguished Service Medal.

Nitpick: When the principal is introducing Dana Taylor to the audience, she calls her Corporal Taylor. However, the insignia on her class A dress uniform is that of a Specialist. Technically, they are the same grade (E-4 versus SP-4), however, a corporal (E-4) is usually a command rank, whereas a specialist (SP-4) is a non-command rank.

Nitpick: This episode features a major lapse in military knowledge. United States Marines would never refer to themselves as "soldiers" as the characters do here, but instead as marines. Soldiers are members of the US Army (infantry). They might refer to themselves as "warriors" or "fighting men" (women) in general terms, but they are always marines.

Some of the names in the boys' yearbook – in addition to Cameron Coulter and Neil Hanlon – are Michael Washington, Alan White, Steve Carter, Debbie Harris, Jennifer Johnson, and Mary Jones.

Jennifer Johnson is also the name of one of the supervising producers on the show, who joins the production staff in Season 4.

Some of the names of the mall massacre victims are:
- Wieland, R., case no. H95-248
- Fehervari, K., case no. H95-258
- Hall, C., case no. H95-251
- Hopper, G., case no. H95-247

Cameron Coulter, Neal Hanlon, and their 15 victims died on September 23, 1995.

Highlight for a spoiler:
Orlando was killed on March 9, 2005. Wilder Dautry died two months later in May 2005.

Highlight for a spoiler:
Det. Jeffries is relieved of his desk duty when Lt. Stillman strikes a deal with the new ADA to solve Grant Bowen's case.

Goof: The show begins in a hospital in 1984 with Grant Bowen attending a heart attack victim, identifying him as a "55-year-old that needs a stent". However, the first coronary stent was not implanted in a human until two years later in 1986 in France. The first coronary stent in the US was not implanted until 1987 and was not approved for general medical use until 1993.

Grant Bowen died in August 1984.
