This pipe bomb was attached to Cyndi Steele's car June 15 when she went to a Coeur d'Alene auto shop for a routine oil change. The photo was shown to jurors today in Edgar Steele's murder-for-hire trial.

A Spokane woman picked up a suspicious device and transported it across town before contacting authorities Sunday.

Police say the woman located the device in the area of 2800 E. Diamond Ave., then transported it to an apartment at 1405 N. Lincoln St .

A few hours later, at 9:30 p.m., she decided she didn't feel safe, took the device outside and called police. A bomb robot examined the device, and police concluded it “to be a small but crude attempt at a sparkler bomb,” according to a news release.

Police don't believe the device was intended to injure or scare anyone. They urge citizens to call them “PRIOR to moving any suspicious device or package.”

An explosive device was found during a traffic stop on Interstate 90 in Coeur d’Alene Sunday night.

Julianne M. Lewis, of Pasco, and William F. Heavyrunner, of Browning, Mont., were arrested near milepost 13 after Idaho State Police troopers found the device in their vehicle, along with drugs and guns, according to a news release.

A bomb squad from the Spokane County Sheriff’s Office disposed of the device. Idaho State Police declined to release further information, citing an ongoing investigation.

Lewis and Heavyrunner were booked into Kootenai County Jail on charges of reckless driving and possession of a controlled substance.

Heavyrunner also is charged with posession of a dangerous weapon and Lewis is charged with posession of drug parapheranlia.
