Law enforcement officers came on their day off Saturday to power wash the walls of a new memorial, a day before the dedication and memorial service for the more than 60 officers who died while in the line of duty.

Beforehand, the walls were covered with what appeared to be bicycle or skateboard tire marks.

The Hawaii Law Enforcement Memorial on the Civic Service grounds has been in the works since 2010 to honor officers from city, county, state, military and federal agencies.

Veteran HPD Major Kurt Kendro, along with other volunteers, wiped down plaques of friends and colleagues he once knew.

“I was outraged and mad and angry and just sad,” said Kendro. “Behind every name on this wall is a story, and it’s not how they died that they were heroes, it’s how they lived.

“I worked with many of them, so it’s real hard in that respect. It’s sad to see it, but if it happens again tomorrow, I’ll come back tomorrow.”

State sheriff deputies will keep watch over the memorial until the dedication on Sunday at 6 p.m. Security options are being looked at to monitor the area.
