(AP) — A portion of the Wahoo Public Library ceiling has collapsed under the weight of accumulated water.

A frozen line for the fire suppression system had burst Tuesday, allowing water to pool until it overcame the ceiling material and taped joints.

Library workers had spotted water leaking from the ceiling in the children’s area and called the fire department. Firefighters found the bulging ceiling threatening to burst, so firefighters and city workers raced to cover bookshelves with plastic tarps before the ceiling finally gave way.

Workers will take some water-damaged books in plastic-lined boxes to a nearby meat locker, where they will be freeze-dried to prevent mold. Most of the library’s 32,000 volumes will be removed so workers can repair the ceiling and replace carpeting.

(AP) — Families with children or dependents could qualify for a slightly larger tax credit under a bill introduced in the Legislature.

Sen. Kate Bolz proposed legislation Wednesday that would increase the credit for families who have an adjusted gross income of $29,000 or more per year.

The proposal would allow them to claim up to 28 percent of their child care expenses, up from the current 25 percent. The credit is nonrefundable, so it couldn’t reduce a family’s tax liability to less than zero.

Bolz says she introduced the bill because of increases in the cost of child care. Families making less than $29,000 receive larger tax credits for child care expenses, depending on their income.

(AP) — Lincoln’s mayor has made it clear to residents and police: No drones here.

A general order issued last month by Mayor Chris Beutler included the ban. Other cities across the country have begun using the remote-controlled eyes in the sky to help catch crooks and aid in other public safety incidents.

Beutler says city officials must understand the emerging technology of drones before police buy any and employ them.

(AP) — Authorities say a 16-year-old boy has been hospitalized after setting himself on fire outside an Omaha home.

The Omaha Police Department says it received a report Tuesday night about a teen who doused himself with an accelerant and set himself on fire.

A police report indicates the boy set himself on fire outside his ex-girlfriend’s home. Witnesses told police they saw the boy and girl first arguing at another location.

Police say the boy, whose name has not been released, was taken to a local hospital with injuries that were life-threatening. Additional information about his condition is not available.

(AP) — A judge has set a Feb. 12 hearing to rule on whether a man accused of four Omaha slayings is competent to stand trial.

Twenty-seven-year-old Nikko Jenkins is charged with first-degree murder in the deaths of Juan Uribe-Pena, Jorge Cajiga-Ruiz, Curtis Bradford and Andrea Kruger. The four were killed within three weeks of Jenkins’ release from prison on July 30.

A state Ombudsman’s Office report released Tuesday said prison officials should have done more to get treatment for Jenkins.

Jenkins has pleaded not guilty but has said he wants to change his plea to guilty. The judge has said he won’t consider a plea change until he determines whether Jenkins in competent for trial.

A psychiatrist working for prosecutors says Jenkins is competent. A defense psychiatrist says Jenkins is not.

(AP) — A Catholic high school in Omaha has plans to require random drug and alcohol testing for all students.

Creighton Preparatory School said Wednesday that the testing will begin in the 2014-2015 school year. The school already requires tests for performance-enhancing drugs on its student athletes.

Starting in August 2014, hair samples will be taken and tested for binge drinking, marijuana, PCPs, amphetamines, cocaine and opiates.

Students who test positive will be enrolled in an evaluation and support program with additional testing 90 days later. A second positive test will result in a review for disciplinary action. A student will be dismissed from school for a third positive test.

Public schools can require such tests only for students participating in extracurricular activities.

(AP) — A 51-year-old southeast Nebraska man has been sentenced to federal prison for receiving and possessing child pornography.

The office of U.S. Attorney Deborah Gilg says Christopher Bohlen, of Douglas, was given five years for receiving child pornography and a year and a day for possessing child pornography. The sentences are to be served at the same time.

Bohlen must serve five years of supervised release after he leaves prison.

Bohlen was identified as a child pornography suspect after the U.S. Postal Inspection Service noted correspondence to Bohlen from a website offering images of children.

Investigators say they found about 47,000 image files of child pornography on Bohlen’s computers. The images included some of children ranging from 2 to 12 years of age involved in sexual and sadomasochistic conduct.
