DAYTON, Iowa (AP) — Authorities are scaling back their search for a missing Iowa teenager abducted from a rural school bus stop this week. The state Department of Public Safety says trained law enforcement will narrow their search around Dayton today for 15-year-old Kathlynn Shepard. Authorities say they’re focusing on terrain that’s difficult to navigate and requires specialized skills and equipment, so citizen volunteers are not needed this weekend.

CEDAR RAPIDS, Iowa (AP) — Authorities say a suspicious package that required explosives teams to investigate was actually a cooler with food. The Cedar Rapids Police Department says officers were notified about the package yesterday morning. Authorities closed the street where the package was discovered and called in explosive ordinance device teams from Linn County and Marion police.

CHARLES CITY, Iowa (AP) — The Iowa Department of Natural Resources says about 49,000 gallons of ethanol leaked from railroad tanker cars after a derailment east of Charles City. The DNR said yesterday this week’s leak into the Little Cedar River was greater than had been previously estimated, but initial monitoring indicates normal oxygen levels in the river. Workers haven’t found any dead or distressed fish downstream so far.
