SCAM ALERT! Please be aware of yet another scam to steal your money. The Mercer County Sheriff's Office or any local law enforcement agency will never reach out to you for money, gift cards, Venmo, or Bitcoin, etc. It's a scam!
- Sheriff Jack Kemler

Several residents have recently received scam calls from individuals claiming to be officers from the Mercer County Sherriff’s Office, stating there is a warrant for missing jury duty and demanding large sums of money to avoid arrest.
Please remember:
• Law enforcement agencies will NEVER request payment through Bitcoin, Venmo, CashApp, gift cards, or similar apps.
• New Jersey does NOT have monetary bail on criminal warrants.
If you receive one of these calls from Mercer County Sheriff’s Office or any other law enforcement agency, contact the agency directly using an official phone number to verify the information. Do not send money or provide personal information.

THIS WEEK IS NATIONAL PUBLIC SAFETY TELECOMMUNICATORS-DISPATCHERS WEEK

I want to thank our dedicated Mercer County Sheriff's Office Dispatchers, along with all state, county, and local emergency dispatchers, including the teams at our County's Office of Emergency Management and Emergency Service Center.

Their jobs are critical to public safety. They often manage urgent situations from the start, using their professional skill sets and high-speed telephones, radios, and computers to dispatch first responders to any imaginable problem or life-threatening situation.

They work to make our communities safer from the first ring of the phone, answering emergency calls 24/7 - 365 days a year, dispatching emergency professionals and equipment, running criminal checks, monitoring critical situations, and even rendering life-saving assistance to those in need – while on the line.

We appreciate and support our dispatchers.

RAISE YOUR AWARENESS, NOT YOUR CELL PHONE

When you keep your eyes on the road, you help keep everyone safe. April is Distracted Driving Awareness Month -a time to remember that even a moment of distraction can have serious consequences. Every year, thousands of accidents are caused by drivers who take their attention off the road, often to check a message or glance at their phone.

Let’s do our part by putting our phones away, staying alert, and watching out for pedestrians, cyclists, and other vehicles. Remember, your safety and the safety of others depend on your focus behind the wheel. Make a commitment this month and beyond to drive responsibly and help end distracted driving in our community.

Stay focused, drive safely, and set a positive example for everyone on the road.
