Which of the following is NOT considered a role for the evidence custodian regarding a mobile tracking device?

The role of an evidence custodian primarily revolves around the management and safeguarding of evidence, ensuring its integrity throughout the investigative process. The responsibilities include maintaining the condition of the device, documenting its use to keep a thorough record of its application in investigations, and transferring it when necessary to other authorized personnel.

Activating the mobile tracking device falls outside the traditional scope of the evidence custodian's responsibilities. The activation of such devices typically involves technical expertise and operational decision-making often performed by law enforcement or technical staff. Therefore, the evidence custodian's focus is on overseeing the chain of custody, proper documentation, and ensuring that the device is available and intact without engaging in its operational use.
