Best practice
When using "were not identified", ensure the context clearly indicates who or what was not identified and why that information is relevant. For instance, in crime reporting, it's crucial to state that "the suspects "were not identified"" to manage public expectations and avoid speculation.
Common error
Avoid using "was not identified" when referring to multiple subjects. Always use the plural form "were not identified" when the subject is plural. For example, it should be "The victims "were not identified"", not "The victims was not identified".
