2) Evidence that may have been taken away by Lefty

- Mud from the mansion stuck on the tires (wheels spinning in the muddy shoulder)

- Seeds/pollen grains from jacaranda tree stuck under his shoes (Lewis parked his car under a jacaranda tree, therefore he might have stepped on them)

- Small glass shards stuck in his wound (from glass pane)

- Mud on shoe (walked across the flowerbed)

- Parts of Jacaranda tree stuck on the car (wet weather, might be pollen or some flower)

- Parts of creeper stuck to his shirt (while climbing)

3) Suggestions for the forensic scientist


- Check for fingerprints at the crime scene eg. The Torch that the guy dropped
- Compare the blood sample obtained at the crime scene with the guy's blood
- Check the tyre tracks left behind by the guy's car
- Trace the oil leaks/tyre tracks
- Search the guy's house for the stolen items
