Yes. Group chats, texts, direct messages, photos and videos can be evidence in a hazing case. They can show what was planned before an event, what happened during it and what people said afterward. What any single message proves depends on who sent it, whether it can be shown to be genuine, and the law that applies.
You may be a student who was in a pledge chat that went too far. You may be a parent who was shown screenshots after your child was hurt, or a family that learned of the group chat only after a death. In each case the question is the same: what do these messages mean legally, and could they disappear? This page explains how messages fit into a hazing case, why originals matter, how chats get lost and how the legal process can reach messages no one in the family has seen.
