c. the zone method dividing the crime scene into indoor and outdoor zones
d. the strip method starting in the front yard

Explanation:

1. Witness names and numbers are typically collected during interviews, not during the initial search of the crime scene. Investigators focus on physical evidence like altered items, narcotics, and potential murder weapons.
2. The spiral search method is best for a large area with a specific point (like where the perpetrator might have started discarding the tool) from which to search outward.
3. In the wheel search method, as one moves further from the origin point, the area an individual has to search increases (since it's like the spokes of a wheel - the further out, the more area per'spoke').
4. In the strip method, each search lane for individuals is no wider than each person’s wingspan to ensure thorough coverage without missing evidence.
5. Since there is a specific starting - point (the victim's best estimate of where the tool was thrown from - which can be the origin for the spiral search), the spiral method starting from that point is appropriate.
