WINSLOW — Police are investigating after two misdelivered packages were found to contain nearly 30 pounds of pills believed to be fentanyl with a street value of up to $2 million.

In a news release issued Wednesday, Winslow police said the department received a complaint that a resident had been delivered an unexpected package from California on Friday; the resident had not ordered anything nor was any delivery expected.

When the package was opened, it contained multiple bags of pills. They tested presumptively positive for fentanyl, a potent synthetic opioid, police said.

A second package containing more pills was delivered Saturday.

The total weight of the pills is approximately 29½ pounds. Police estimated the street value could be as much as $2 million.

Winslow Deputy Police Chief Randy Wing said in the news release that the investigation is ongoing, and no further information is available for release.
