Sgt. Kunovich collapsed moments after the subject was disarmed and “relentless lifesaving measures” were initiated by St. Johns County Fire Rescue and Flagler Health+ personnel, SJSO said. He was ultimately pronounced dead shortly after being taken to Flagler Hospital.

A medical examiner ruled that Sgt. Kunovich died of natural causes and was dealing with respiratory issues.

An order for a mental examination was ordered by the judge late last year. That examination of the defendant was necessary to determine if Aguilar-Mendez met certain criteria to stand trial. This included:

  • Does the defendant understand the charges?
  • Does the defendant understand the possible penalties?
  • Does the defendant understand the legal process?
  • Can the defendant testify?
  • Can the defendant communicate facts to his attorney?

The judge also ordered a mental examination to determine to what extent of mental illness does Aguilar-Mendez suffer from.
