Summary
The Nebraska Supreme Court affirmed Billy R. Aguilar's convictions for first degree assault, burglary, attempted first degree murder, and two counts of using a weapon to commit a felony. The court held that a trial court may conduct a Daubert hearing during trial and that replacing an improperly seated juror with an alternate juror did not require a mistrial. The court also upheld the admission of expert gunshot-residue testimony, handwriting identification testimony, and other challenged evidence.

Questions Presented
- Whether the district court abused its discretion by conducting a Daubert hearing during trial rather than before trial.
- Whether Aguilar was entitled to a mistrial after a juror who had been stricken was inadvertently seated for part of the trial and then replaced by an alternate juror.
- Whether the district court erred in admitting gunshot-residue expert testimony when the expert was not personally familiar with the manufacturer of the calibration standards.
- Whether the district court erred in admitting nonexpert handwriting-identification testimony based on familiarity acquired before litigation.
- Whether the remaining challenged evidentiary rulings required reversal.
Holdings
- A trial court has discretion to conduct a Daubert hearing during trial when the need for such a hearing arises; a separate pretrial hearing is not mandatory.
- For purposes of Neb. Rev. Stat. § 29-2004, a regular juror is a juror who took the oath and was seated, even if seated erroneously; the district court therefore could replace the juror with an alternate, and Aguilar was not entitled to a mistrial.
- The district court did not err in allowing Morris to testify as an expert because personal familiarity with the manufacture or supply of calibration standards was not required when the expert was qualified to operate the testing devices and interpret their results.
- The district court properly admitted Mario's testimony identifying Aguilar's handwriting because Mario's familiarity was acquired through prior personal observation and not for purposes of litigation.
Key quotations
“We also agree that the trial court has the discretion to hold a Daubert hearing during trial when the need for one arises.” (at 354)
“Thus, we conclude that a "regular juror" for purposes of §29-2004 is a juror who took an oath and was seated, whether erroneously or not.” (at 355)
Factual background
Aguilar's cousin Mario testified that Aguilar had made statements indicating he heard Mario's voice and had repeatedly appeared near Mario's workplace and home. Mario identified Aguilar as the masked person who attacked him with a knife and later as the masked intruder who shot him three times after breaking into his home. The State presented gunshot-residue evidence from Aguilar's sweatshirt through expert Joseph Morris and handwriting testimony identifying Aguilar's writing on a page containing information about guns.
Procedural history
A jury convicted Aguilar of the charged offenses identified in the opinion and acquitted him of stalking. The district court imposed varying concurrent and consecutive prison terms. Aguilar appealed, challenging the timing of a Daubert hearing, the denial of a mistrial after a juror-composition error, the admission and foundation of expert and handwriting testimony, and numerous other evidentiary rulings.
