Black leather briefcase with brass lock

I lost a black leather Samsonite briefcase yesterday around 3pm near the Safeway on 4th Street in Eureka, Humboldt County. It's medium-sized, about 16 inches wide, with a slightly worn handle and a brass buckle-style lock that sticks. Inside there's a gray USB-C charger, a red spiral notebook, and a faded photo tucked in the main pocket. On the inside pocket there's a small silver sticker with the initials 'P.K.' and a faint coffee stain on the front. This briefcase holds important work documents from my job and has sentimental value because it belonged to my late uncle; I really need it back—if found, please email me at [email protected].
