Interim police chief Martin Cigich said the items were found outside Leavenworth County after police conducted interviews with “people of interest” in their investigation.

Police have made no arrests in the case, but Cigich said there are people in custody outside Leavenworth County who have knowledge of the thefts.

Last week, either late Tuesday or early Wednesday, someone broke into the treatment facility and removed high-end tools, computer equipment, cash and other items valued at more than $100,000.

“There’s still a lot of items and tools that still need to be recovered,” the police chief said.

Cigich said a dollar figure could not be placed on the items recovered from the theft.

Also, the police chief said he could not comment on most aspects of the investigation.

“It’s an on-going investigation,” he said. “We’re working hard to solve it.”

Last week, city superintendent Gene Myracle said he believed more than one person committed the burglary. He said he based the opinion on the type and size of items removed from the treatment plant, saying one person alone could not have moved several pieces of equipment taken.

Once inside the sewage treatment plant, which doubles as the office and equipment storage space for the city’s public works department, thieves found keys used to steal the truck and gain entrance to other parts of the facility.

Myracle said gates to the facility were locked when employees left about 4:30 p.m. Tuesday.

A public works employee noticed a set of keys in the outside gates when he arrived for work at 7:10 a.m. Wednesday.

The sewage treatment facility did not have an alarm system.
