A suspect is alleged to have hit a victim using a 2x4" wood board. The victim is bleeding and is suffering from this type of wounding pattern:

• Blunt force trauma

• Dermal tag

• Contusion

• Laceration

A victim has a 2" wide wound that is bleeding and it has smooth edges. The weapon that was likely used is:

• A baseball bat

• A knife

• A firearm

• A hammer

The order in which multiple skull fractures occurred can be determined based on where the fractures meet.
