CHICAGO (AP) — A summer jobs program that engaged mentors to help troubled kids in Chicago stay on track is linked with a big reduction in youth arrests for violent crimes.

The results suggest that a low-cost public program can reap big benefits. The findings also support arguments that employment alone cannot resolve poverty-related ills.

The study’s author and other experts say the results are promising.

Chicago’s eight-week program began in 2012 and gives jobs to thousands of disadvantaged kids. The study involved the first year and found 43 percent fewer violent crime arrests for kids involved, compared with a control group.

The study was released Thursday by the journal Science.

OMAHA, Neb. (AP) — On his second attempt, an Omaha attorney successfully pleaded guilty to helping run a Ponzi scheme.

Michael Kratville failed to satisfy U.S. District Judge Joseph Bataillon on Monday because he failed to admit his guilt properly.

Kratville is one of three people indicted for operating a Ponzi scheme that swindled 100 people out of $4 million.

Kratville succeeded Thursday and was found guilty of wire fraud. In return, prosecutors will seek a prison no more than seven years in prison.

Authorities say Kratville, Jon Arrington and Michael Welke operated two companies, guaranteeing large returns and low risk to investors when they were actually money losers who hid their losses.

Arrington and Welke have each pleaded guilty to one count of wire fraud.

OMAHA, Neb. (AP) — It could be a very happy holiday for the person who bought a winning $166,000 lottery ticket at an Omaha store this week.

The winning numbers drawn in Wednesday’s Nebraska Pick 5 were 5, 8, 12, 23, and 38.

The owner of the ticket has six months to claim the jackpot; winning tickets expire 180 days after the drawing. As with all prizes over $20,000, the jackpot must be claimed in person at the lottery headquarters in Lincoln.

The woman was transported to an area hospital with injuries that police say aren’t critical. The man wasn’t injured.

ATKINSON, Neb. (AP) — A 26-year-old northern Nebraska man has pleaded not guilty to intentional child abuse that authorities say caused the death of his son at an Omaha hospital.

Michael Schroeder, of Atkinson, remains in Holt County Jail on $1 million bail. He’s accused of abusing his 8-month-old son, Kalium Ebsens.

A court affidavit filed by an Atkinson officer says the boy was taken to West Holt Memorial Hospital the night of Oct. 26 after the boy became unresponsive. The infant then was flown to an Omaha hospital, where he died the morning of Oct. 29. The officer said Schroeder acknowledged bumping the boy’s head a couple of times.

DENVER (AP) — Denver authorities say a driver had a medical emergency when he hit and injured four Denver police officers who were monitoring a student protest of the Ferguson, Missouri, grand jury decision.

Police Chief Robert White says one officer was critically injured and was in surgery. He says two of the other three were released from a hospital.

The driver of the vehicle was taken to a hospital for the medical issue. A witness told The Denver Post that he saw a Mercedes run onto a sidewalk and hit the officers before crashing into a Taco Bell.

White says the officers were on hand for the safety of hundreds of East High School students who walked out of class Wednesday and marched to the state Capitol to protest the jury’s decision.

OMAHA, Neb. (AP) — An Omaha man has been given probation for his involvement in a car crash earlier this year that killed his girlfriend.

A judge sentenced 26-year-old Nicholas Marescalco on Wednesday to five years of probation on a manslaughter charge.

Prosecutors said Marescalco was driving when he intentionally crashed the vehicle into a pole in July. Twenty-five-year-old Sharlee Arnett, a passenger in the car, was killed.

The judge told Marescalco he issued probation instead of a short prison sentence so he could monitor him longer.

Millard Public Schools spokeswoman Rebecca Kleeman says the student brought the brownies to Millard North High School on Nov. 25.

Kleeman says the student was ticketed by police on suspicion of assault and was disciplined by the district for violating its code of conduct. She did not elaborate.

Kasun is accused of stabbing and slashing a man Tuesday night following a fight between the two and Kasun’s boyfriend. The man was taken to a local hospital in critical condition but with non-life-threatening injuries. He was in serious but stable condition Wednesday morning.

Police say Kasun fled the scene after the attack. She was later arrested.
