King County Sheriff's Office presented Mercer Island Police Department Officers Shannon Johnson (pictured, at left) and Jordan Tranter (second from right) with the King County Lifesaving Award for their heroic actions during an ice rescue that occurred on Fish Lake in Chelan County in early February.

KCSO Special Operations Division Chief Jose Marenco (right) and King County Marine Patrol Sergeant Rich Barton (second from left) presented the awards in recognition of the officers’ swift response and lifesaving efforts after a person fell through the ice. They were part of a 20-person crew who were fortuitously participating in an ice rescue training session nearby when they witnessed a man punch through the ice and into the 35-degree water. The entire team sprang into action to pluck the man from the icy water, saving his life.

The professionalism, teamwork, and dedication to public safety of Officers Tranter and Johnson reflect the highest standards of service and commitment to the community.

⚠️ Scam Alert! The Mercer Island Police Department (MIPD) is warning residents and business owners about an increase in fraudulent locksmith stickers being placed on commercial buildings throughout the area.
These stickers often advertise locksmith services with phone numbers that may be linked to scam operations. Individuals who call these numbers may be overcharged, receive substandard service, or become victims of fraud.

What to watch for:
• Stickers placed near door locks, entryways, or building exteriors
• Generic or unfamiliar company names
• Phone numbers without a local or verifiable business presence

What you can do:
• Only use locksmith companies you know and trust
• Verify businesses before calling—look for established, reputable providers
• Remove suspicious stickers if found on your property
• Remain alert for any unusual or suspicious activity

If you observe someone placing these stickers or notice suspicious circumstances, call the MIPD's non-emergency line: 425-577-5656.

It’s been a busy March for Mercer Island Police Department (MIPD) officers, who have had many opportunities to engage with and assist the community. From daring rescues to coffee shop chats, here’s just a glimpse of what they've been up to:

Above and Beyond (the Retaining Wall): Officer McDowell proved that "protect and serve" extends to our four-legged residents, too! When a local pup took an accidental leap over a retaining wall and ended up trapped in thick sticker bushes, he didn't hesitate. Armed with an axe and some serious determination, he successfully extricated the dog. We’re happy to report the pup is safe, and the owner was ecstatic! 🐕✨

Starting Young with Safety: Officer Udodik from our Crime Prevention Team spent some quality time at Bright Horizons childcare center, where she spoke with some of our youngest residents about staying safe!

Coffee & Conversation: Chief Michelle Bennett and several officers recently set up shop at Starbucks for some face-to-face time with the community. They covered everything from neighborhood safety to the best way to report concerns.

Mercer Island drivers, let’s keep our neighbors safe. Remember, motorists must stop for pedestrians in all crosswalks—whether marked or unmarked. This is not just best practice, it’s the law.

When a pedestrian is present, remain stopped until they have completely cleared your lane. In school zones, you must wait until the crossing guard has returned to the sidewalk before proceeding. Also, never pass a vehicle stopped for a pedestrian.

Safety is a shared responsibility. Drivers, stay alert, ditch the distractions, and slow down. Pedestrians, make eye contact with drivers and look both ways before crossing. Let’s ensure everyone makes it home safely!
