Which type of contact information is important to collect from interview subjects?

Collecting an email address from interview subjects is important for a variety of reasons in a criminal investigation. It serves as a critical means of communication, allowing investigators to follow up for additional information or clarification after the initial interview. An email address can also be invaluable for sending important documents, updates on the case, or further instructions to the subject.

Additionally, digital communication through email can facilitate a quicker response, especially if the subject may not be easily reachable through traditional methods like phone calls or in-person interviews. Email records can also be relevant in investigations if there is any need to establish timelines or interactions between individuals involved in the case.

While social media accounts, relationship to the victim, and employment records can provide useful context and insight into a case, the email address is a direct tool for communication and information gathering, making it particularly vital to collect during interviews.
