Final answer:
DA Peters may have had various reasons for not wanting to reopen the case, such as the time and resources it would require and the statute of limitations. It is also possible that there was a lack of new evidence or major developments to justify reopening the case.
Step-by-step explanation:
DA Peters may have had several reasons for not wanting to reopen the case. One possible reason is that reopening the case would require a significant amount of time and resources. The case may have been considered resolved or closed due to the statute of limitations, which sets a time limit for bringing a legal action. Another reason could be that there may not have been enough new evidence or significant developments to warrant reopening the case.
