Mountain View man charged with assaulting two Keaʻau police officers

Sep 22, 2026

A Hawaii Island man faces charges after allegedly attacking two officers during an arrest, a bad outcome for him and a reminder of the risks patrol officers face on routine calls.

  • Prosecutors charged 44-year-old Justin Santagani of Mountain View over an incident last Friday.
  • Officers were called to a Keaʻau shopping center for a disturbance and say he approached them and turned aggressive.
  • During the arrest he allegedly headbutted one officer and kicked the other in the chest several times.
  • Both officers were assaulted during what began as a routine disturbance call.

Outlook: The case moves forward in Hawaii Island courts, where assault-on-an-officer charges carry serious penalties.
