Blackman PPD accepted the arrest of Casillas and issued a notice for him to appear in court. In a video posted to Nextdoor, Casillas admitted to painting a heart on the sign. "I want to let you know that, yes, I painted the heart on the illegal sign on Rockaway. I felt negative signs that have gone up around town are ridiculous, and I painted the heart to bring some humor and levity to the situation." Casillas went on to say he didn't mean to cause harm by painting the sign. "My intent was not to be malicious. I painted a heart. It was wrong.
