Miami-Dade County Deputy Mayor Genaro "Chip" Iglesias and Miami-Dade Police Deputy Director Juan Perez will visit Thursday with the detective and his family while assisting in the search Morales.
Pardinas, 54, and another Miami-Dade detective had stopped at a Dallas-area Walmart Monday night with Morales. While one detective was inside, Morales used a sharp piece broken from his eyeglasses to stab Pardinas and flee. Morales was being transported from Florida to Nevada.
Dark-colored video showed Morales outside the store as he walked away from a grey sport-utility vehicle.
