Gray knit beanie with fox patch, lost near Arsenal Street

I lost my gray knit beanie yesterday around 3pm near the Watertown Mall on Arsenal Street. It's a medium-weight acrylic beanie from North Face, with a small embroidered fox patch on the cuff and a faint coffee stain on the inner label. The fabric is a bit pilly on the sides but still cozy. It was a gift from my sister last winter, and it means a lot to me—it's the warmest thing I own for these chilly Watertown mornings, so I'm really hoping someone found it. If anyone found it, please drop it at the Watertown Police Station lobby or reply here so I can get it back.

Blue ID badge with photo and lanyard

I lost my blue employee ID badge yesterday around 3pm near the Watertown Public Library on Oak Street, outside the main entrance by the bus stop. It's a laminated plastic badge with my photo, a TechSphere Solutions crest in the upper-left corner, and a blue woven lanyard. There's a coffee stain along the bottom edge and a tiny scratch on the corner, plus a sticky note on the back with my initials 'PK' and a work number scribbled. It's my key to getting into the building, and I really need it back so I don't get blocked at work.

Black Anker Bluetooth speaker with dented rim

I lost my black Anker Soundcore portable Bluetooth speaker yesterday around 3pm near the Starbucks at Watertown Square on Main Street. It's about 6 inches long, with a matte black finish and a small dent on the top rim. I noticed a blue fabric strap that is part of the charging cable loop, and there’s a tiny sticker with my initials 'PP' on the bottom. It’s important to me because I use it daily for audiobooks during workouts, and I really need it back. If you found it, you can drop it off at the Watertown Public Library or reply to this listing and we can arrange a pickup.

Navy cashmere scarf with silver thread

I lost my navy cashmere scarf yesterday around 3pm near the Watertown Public Library on Main Street. It's a lightweight scarf, about 60 inches long, with a subtle silver thread woven throughout and a tiny moth hole at the bottom left corner. There’s a small tag inside that reads Nordic Knit Co. It was a gift from my grandmother and has sentimental value, so I’m really hoping someone picked it up. If you found it, I’d be grateful to arrange a quick meetup near the library or outside the coffee shop on Main Street to grab it back.

Calico guinea pig with blue harness

Hi, I’m Amina. I lost my calico guinea pig yesterday around 3:15pm. Her name is Nibbles. She escaped from her cage while we were at the Watertown Public Library on Main Street, near the reference desk. She’s small, about a pound and a half, with calico fur in orange, black, and white, plus a white bib on her chest and a tiny black spot on her left ear. She wears a blue fleece harness with a tiny silver bell. She’s very friendly but shy, and my daughter is crushed—we really need her back. If you spotted a little guinea pig around that area, please drop a note here and we’ll arrange pickup.

Found missing person: man in navy jacket near library

I found a man wandering near the Watertown Public Library parking lot this afternoon around 4:15pm. He is about 6 feet tall, with short black hair and light stubble, wearing a navy blue North Face windbreaker over a gray hoodie and black jeans. He is carrying a red backpack with a blue keychain and wears a silver bracelet on his left wrist. He looked anxious, kept checking his phone, and asked for help contacting his family. I posted this here hoping to help reunite him with someone who is worried about him; if this sounds like your loved one, share some distinguishing details so we can set up a safe meetup.

Black Samsonite suitcase with blue tag

I found a black 28-inch Samsonite suitcase yesterday afternoon around 4pm by the entrance to the Watertown Mall on Main Street. It’s in decent condition with a few scuffs and a dent on the front left corner. There’s a bright blue luggage tag on the handle with the initials A.Y. and a small travel sticker. Inside I spotted a plaid scarf and a folded umbrella, hinting at recent travel. I know how stressful losing a bag can be, so I’d love to get it back to its owner—meetups near the Watertown Public Library are fine if you can verify ownership.

Gray Anker Bluetooth speaker found near Watertown Library

I found a gray Anker Soundcore Bluetooth speaker this evening around 7pm in the parking lot behind the Watertown Free Public Library on Main Street. It's about the size of a paperback, with a blue silicone bumper and a small dent on the bottom corner. The top panel shows a little wear, and there’s a panda sticker on the back that says 'Relax'—easy to spot in a crowd. I tested it quickly with my phone and it connected normally, so it seems functional. If this is yours, please reach out—I know how frustrating it is to misplace something that gets a lot of use.

Tan Michael Kors tote found near Watertown Public Library steps

Found a tan Michael Kors tote this morning around 9am near the Watertown Public Library steps on Main Street. It's pebble leather with a small gold MK plaque on the front and a long crossbody strap that is a bit scratched from city wear. The interior is black fabric with a zip pocket that holds a pink enamel heart charm on the zipper and a receipt from Luna Boutique dated last Friday. I didn’t recognize any student IDs or cards in there, so I figured the owner would appreciate knowing it turned up. Happy to arrange pickup near the library for whoever lost it.

Found portable projector with case

I found this portable projector this afternoon around 2:15pm in the parking lot behind the Watertown Public Library on Oak Street. It's a compact black cylinder, about the size of a soda can, with a matte finish and a slightly scuffed top rim from travel. It came with a short HDMI cable and a gray carrying bag, and there's a blue sticker on the bottom that reads 'STEM Club - Property' which I thought looked like a school item. If this belongs to someone, I can arrange a quick drop-off at the library front desk.
