What critical information can be determined from email headers in an investigation?

Email headers serve as a vital resource during investigations as they provide detailed information about the transmission of an email. This includes accurate time stamps and IP addresses, which are crucial for establishing timelines and tracing the origin of an email.

The time stamps within the email headers can reveal when the email was sent and received, helping investigators understand the sequence of events. The IP addresses listed can indicate the geographical location from which the email was sent, even offering insights into the sender's network, which aids in identifying potential suspects or corroborating alibis.

This level of detail is fundamental in forensic investigations, allowing investigators to build a clearer picture of communications and actions related to a case.
