Sergio Sebastian Gonzalez v. State of Mississippi, 243 So. 3d 244

Sergio Sebastian Gonzalez entered his estranged wife Gina’s home in violation of a protective order, found Andres Gonzalez there, and a physical altercation occurred in which Andres was stabbed and airlifted to the hospital.
Gonzalez later turned himself in and was charged with aggravated assault; he testified at trial claiming self-defense and that he had sustained bites and bruises during the struggle.
On rebuttal the State called two jailers who handled Gonzalez’s booking; they testified they observed no cuts, bruises, or bite marks when he arrived.
The State introduced an unsigned, undated, mostly-blank medical screening form (S-16) prepared at booking, which the jailer said reflected Gonzalez’s negative answers and lack of observable injuries.
Gonzalez objected at trial that the medical form had not been produced in discovery and later raised related objections on appeal (improper surprise, improper rebuttal, and that the blank form should not be substantive proof).
The trial court admitted the form as rebuttal evidence; on appeal the Court of Appeals affirmed, finding no reversible error and that any error was waived or harmless.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Discovery violation (untimely production of medical form)	The State failed to disclose the form in discovery so it should have been excluded.	The form was rebuttal evidence; defense did not request continuance or mistrial after being given opportunity.	Overruled; failure to request continuance waived the claim, and any error was harmless.
Improper use as rebuttal evidence	Admission on rebuttal ambushed Gonzalez; should have been in State’s case-in-chief.	The form rebutted Gonzalez’s testimony that he suffered bite marks and bruises.	Overruled; trial court reasonably admitted it as rebuttal.
Sufficiency/substantive weight of an unsigned/blank form	A blank/unsigned medical form cannot be used as substantive proof Gonzalez had no injuries.	Issue not raised at trial; no authority cited on appeal; thus not preserved.	Not addressed on merits; forfeited for appeal and unpreserved.
Harmless error	Admission was prejudicial and warrants reversal.	Witness testimony (victim and wife) and jailers corroborated that Gonzalez attacked and arrived without injuries; error, if any, harmless.	Held harmless; conviction affirmed.
