Greenburgh police and the Westchester District Attorney's Office are working together to find out who vandalized a Black Lives Matter sign in East Irvington on the one-year anniversary of George Floyd's death.

This sign was just put up two days ago, and someone spray-painted white paint over the Black Lives Matter message.

The owners of the sign, Roger Burkhardt and Jane Kankhanel, say they are not surprised.

They say this is their fifth Black Lives Matter sign this year.

The previous four have either been stolen or ruined, they say.

When nearby communities found out about the vandalism, they immediately jumped into action. Some cleaned the vandalized sign.

Others made their own to display to show solidarity.
