Read the autopsy carefully.

Evelyn was strangled and had red fibers under her fingernails (which suggests she was tugging at whatever was strangling her).

The spell in the pink bag lists the birthstone of the person casting the spell as an ingredient. There is a purple stone in the bag. We can infer that the person who owns the pink bag has a purple birthstone.

On the digital extraction of Luna's computer, there is a diagram that depicts the birthstones for each astrological sign. The birthstone that looks most like the purple stone is the Aquarius' birthstone (an amethyst). Aquariuses are born between January 20th and February 18th. Based on the birth dates listed on the witness statements, Luna is the only Aquarius (born February 10th, 1986). The pink bag is Luna's.

The 4 relevant pieces of evidence are: Purple Stone, Spell, Digital Extraction of Luna Brooks' Computer, and Suspect's Witness Statement or Police Interview (Luna's witness statement).
