Dark blue US passport with red sticker

I lost my dark blue US passport yesterday around 3pm near the Starline Diner on Stanton Street in El Paso. The cover bears the gold UNITED STATES OF AMERICA lettering and the biometric icon, and there's a light coffee ring on the back. Inside, I slapped a small red sticker with my initials AK on the inner cover so I could recognize it quickly if it turned up. This passport is essential for upcoming travel; I have a flight booked next week and really need it back.
