Police tracking down sender of package to Bullock

HELENA (AP) — A Helena police official says authorities are trying to track down the anonymous sender of a package that caused the evacuation of the state Capitol.

State workers were told to go home for the day Wednesday while officials checked the package sent to Gov. Steve Bullock's office for hazardous materials.

Helena Fire Department officials say the tests came up negative.

But Helena Police Capt. Curt Stinson said Friday a culture test is being conducted to ensure the package did not contain substance that could develop into a hazardous material.

The box contained documents, letters and cloth.

Stinson declined to describe the contents further, but says they are of interest to police.

He says authorities are making progress in identifying the sender and are considering possible charge
