(At least three sentences)  DNA analysis on the light and dark hair samples.  Fingerprint comparison on the note, the flowers, the broken glass, the bloody fingerprints on the water fountain and near the back door on the door frame, the dead body.  Toxicology analysis/drug testing  Glass analysis broken glass near the victim’s left leg.  Soil analysis thin trail of dirt leading from the back door, the footprint in the garden.  Hair analysis Short, brown hairs stuck to the victim’s pants, the medium length blonde hair caught between the wooden planks.  Fiber analysis the victim’s pants, the pink rug.  Ballistic/firearm analysis  Blood spatter analysis bloodstain on the sharp corner of the table, pool of blood on the pink rug.  Impression evidence analysis the bloody fingerprints on the water fountain and near the back door on the door frame, the footprint in the garden, the dead body.

(At least one sentence) There’s no evidence that requires to determine chemical properties.  Could any of the evidence have class characteristics or individual characteristics that would help the investigation? Which items? What are their possible class and individual characteristics, and how could you use those in the investigation?
