E-bikes are an increasingly popular mode of transportation on Mercer Island. The City of Mercer Island wants to hear from you about how e-bikes are used and perceived in the community. The Parks and Recreation Commission and the Open Space Conservancy Trust will use the results of this survey to develop a policy recommendation for where and what type of e-bikes can be used in the Island’s public parks, trails, and open spaces.

The Mercer Island Police Department has recovered the body of the 19-year-old Yelm resident who went missing from a vessel on Lake Washington on the night of July 31.

Investigators used cellular phone location data from the victim's phone to significantly narrow the extensive search area. Using side-scan sonar and an underwater remotely operated vehicle (ROV), search teams located the victim in approximately 150 feet of water in Lake Washington. The victim was subsequently recovered and transferred to the custody of the King County Medical Examiner's Office.

The Mercer Island Police Department would like to thank the Seattle Police Department Harbor Unit, King County Sheriff's Office Marine Unit, Coastal Sensing & Survey, and U.S. Coast Guard for providing specialized equipment, personnel, and expertise throughout the search and recovery operation.

Mercer Island Marine Patrol officers and detectives continue to work with the King County Medical Examiner's Office as the investigation is completed. The Medical Examiner's Office will determine the cause and manner of death and will be responsible for the official identification of the victim and any related release of information.

We extend our condolences to the victim's family and friends during this difficult time.

No additional information is being released at this time.

What a fantastic turnout for National Night Out last night on Mercer Island! The Mercer Island Police Department thanks everyone who braved the smoke to come out and celebrate community safety, connection, and neighborhood spirit. MIPD officers and Mercer Island-based firefighters from Eastside Fire & Rescue Station 92 joined in on the fun, visiting 13 neighborhood events across the Island—ranging from ice cream socials to block party potlucks. Bringing out the fire engine proved to be a massive hit with kids and adults alike, and seeing neighbors come together made the evening a resounding success.

We also want to send a huge thank you to the Mercer Island Pagliacci Pizza for donating pizzas to our neighborhood gatherings once again. Pagliacci has been a stellar partner over the years, consistently stepping up to support our community and help make National Night Out extra special. And a huge thank you to all of our incredible block party hosts and residents for making Mercer Island such a vibrant place to live. See you next year!

The Washington Department of Ecology has issued an air quality alert for King County (and nearby counties) through 5 p.m. on Wednesday, Aug. 5, due to smoke blanketing the region from wildfires across Washington state and beyond. Air quality conditions are expected to worsen throughout the day today as smoke begins to mix down to the surface. Particulate matter (PM2.5) concentrations may reach unhealthy levels for sensitive groups.

When air quality reaches this level, individuals, including those with health concerns and pre-existing conditions, should reduce their exposure and take precautions:
• Stay indoors and keep windows closed. Keep your pets indoors, too!
• When using A/C, keep the outdoor air intake closed and clean the filter to prevent outdoor smoke from getting inside.
• If you go outside, avoid exertion and consider wearing a respirator.

SCAM ALERT: Scammers Spoofing Mercer Island Police Department Phone Numbers 🚨

The Mercer Island Police Department (MIPD) is warning residents about a recent uptick in phone scams where callers are pretending to be MIPD officers.
Scammers are using technology to spoof the main MIPD phone line (206-275-7610) so it appears legitimate on your caller ID.

How the Scam Works
• The scammer claims there is an issue with your identity, passport, or other sensitive documents.
• They insist you must immediately "secure your identity" or resolve an urgent legal matter by making a financial payment or deposit—often using gift cards, wire transfers, or cryptocurrency.
• Community members have already reported losses totaling approximately $2,700.

How to Protect Yourself
• MIPD will NEVER call to demand payment, gift cards, or wire transfers. No government agency or police department will ever ask for payment via gift cards or phone transfers to resolve a legal matter.
• Don't trust Caller ID: Numbers can easily be spoofed to look like local city departments, law enforcement, or official agencies.
• Hang up and verify: If you receive a suspicious call claiming to be from the Mercer Island Police Department, hang up immediately. Call MIPD directly at 206-275-7610 (or non-emergency dispatch at 206-577-5656) to confirm if an officer actually tried to contact you.
• Never give out personal information: Do not share social security numbers, banking details, or passcodes over the phone to an unverified caller.

If you or someone you know has fallen victim to a scam or handed over financial details, please report it to MIPD dispatch at 206-577-5656. Please share this alert with your Mercer Island neighbors, friends, and family members to help keep our community safe!
