Final answer:
The suspect should be charged with burglary, as they forcefully entered the locked trunk of a vehicle to commit theft, which fulfills the criteria for burglary.
Step-by-step explanation:
The suspect who used a crowbar to pry open the trunk of a vehicle and removed tools worth $500 should be charged with burglary. Burglary involves unlawful entry into a structure to commit a crime, especially theft. In this case, even though the vehicle's doors were not locked, the use of a crowbar to gain entry into a locked trunk constitutes forced entry, fulfilling the criteria for burglary. Additionally, the value of the stolen items being $500 can elevate the severity of the charge depending on the jurisdiction.
