Officer Chen, Badge #8294
Ongoing investigation of "cosmic graffiti" incidents

For the fourth time this month, we've documented unusual vandalism appearing overnight in areas with no surveillance coverage. Unlike typical graffiti, these markings exhibit properties that defy explanation:

1. Pigments that appear to shift color depending on the viewing angle
2. Patterns that cause optical illusions, reported headaches in some viewers
3. Material that resists standard cleaning methods
4. Faint luminescence detected even under complete darkness

Witnesses report hooded figures working during rainstorms, though surveillance cameras mysteriously malfunction during these periods. Some witnesses have described feeling "strange" after prolonged exposure to the markings.

Det. Ted insists this is simply a new street art collective using experimental materials. I'm not convinced.

These incidents may be related to the increased reports of temporal anomalies in affected areas.
