City: Marysville post office master keys stolen, used to steal mail


MARYSVILLE — The Marysville Post Office had its master keys stolen, and thieves have been taking mail from group mailboxes and collection boxes in the city, according to city officials.

U.S. Postal Service officials have been notifying residents that the suspected thieves apparently used a 3D printer to create copies of keys, said Gloria Hirashima, the city’s chief administrative officer. According to reports, the postal service told residents that it did not have enough funds to replace every lock.

Hirashima warned that important documents could be stolen if they are left in mailboxes. The post office notified Marysville police that “daily thefts” have been occurring from large multi-unit residential mail boxes, as well as blue collection boxes, Hirashima said.

Bridgette Larsen, a spokesperson for the Department, stated that police began investigating on August 8th. Police hadn’t made any arrests related to the thefts, as of Monday, she noted. If anyone has an issue, they can call 911 or the Marysville Police Department’s non-emergency line 425-407-3999.

The Marysville Post Office, postmaster and postal investigator did not immediately respond to a Daily Herald reporter’s phone calls.

Hirashima sent an email to Mayor Jon Nehring stating that residents of Parkview Estates had emailed him in recent weeks, complaining about multiple break-ins.

“Police said without camera footage nothing can be done,” one resident wrote in an email to the city. “My husband talked to the post office, they again said nothing they can do, they can’t afford to change the locks. So now we are vulnerable to have our mail stolen at any time.”

The mail theft suggests a “widespread lack of security” for mail collected and distributed by USPS within zip codes that use these master keys, Hirashima wrote.

Hirashima said the problem covered “at least” the 98270 and 98271 zip codes, potentially tens of thousands of people.

Last week, Marysville police Cmdr. Adam Vermeulen spoke with the Marysville postmaster, and learned the postal inspector was aware of the problem and installed “key grabbers” in some boxes, Hirashima said. The grabbers prevent keys from being used more than once by trapping them after they are used.

Other than that, the postmaster said “there is nothing else they can do,” according to city authorities.

“We would love to see the post office change the locks,” Hirashima said.
