Federal Rule of Evidence 803(2) provides an exception to the rule against hearsay for
A statement relating to a startling event or condition, made while the declarant was under the stress of excitement that it caused.
So, should this excited utterance exception apply to a 911 call about a stolen gun. That was the question addressed by the First Circuit in its recen opinion in United States v. Estes, 2021 WL 128707 (1st Cir. 2021)..
