LINCOLN, Neb. (AP) — Lincoln police say two teenagers attacked a woman and drove over her after she yelled at them to stop driving recklessly.

OMAHA, Neb. (AP) – A northeastern Nebraska farmer is recovering after cutting off his own leg with a pocket knife to save himself from a piece of farm equipment he had become caught in.

Omaha television station KETV reports that 63-year-old Kurt Kaser, of Pender, was unloading corn last month when he got out of his truck and accidentally stepped on the grain hopper opening. An auger in the hopper caught Kaser’s leg, pulling it in and mangling it. An auger is a tube that uses a rotating shaft to suck the grain and push it through the tube to deposit in a bin.

Kaser said he couldn’t pull his leg out and didn’t have his cellphone. There was no one around to help.

So, he took his pocket knife out and sawed off his leg below the knee.

After he was freed, he crawled 150 feet to the nearest phone and was flown to a hospital. Kaser says he never lost consciousness.

On Friday, Kaser was released from a rehabilitation center. He will have to wait for the amputated leg to fully heal before getting a prosthetic leg.

Lincoln Police are investigating after two 10-year-old girls reported that a man attempted to kidnap them from a city park.

On May 13, at around 4:30 p.m., officers responded to Lakeview Park on West Q Street, on the report of a possible attempted kidnapping.

Officers arrived and made contact with the victims and several witnesses.

A 10-year-old female told officers that she was sitting in the park when she was approached by an approximately 20-year-old male who “pulled her into an embrace.”

Police say there was another 10-year-old female who reported that the same subject had walked in her direction and waved at her to come with him. However, she was able to run to a residence in the area and yell for help.

Police say two area residents responded, with one calling 911 and the other following the suspect, who had started to walk away from the park. The resident told police that once he noticed he was being followed, he ran from the scene.

Police and residents flooded the area but were unable to locate the suspect.

Both girls say they do not know the male subject and police say, based on witness and victim statements, they believe he was trying to get either or both girls to go with him.

The case remains under investigation and police ask that anyone with information contact them at 402-441-6000.

NEW YORK (AP) — Walmart is rolling out free next-day delivery on its most popular items, increasing the stakes in the retail shipping wars with Amazon.

The nation’s largest retailer said Tuesday it’s been building a network of more efficient e-commerce distribution centers to make that happen. The next-day service will cover 220,000 popular items from diapers and non-perishable food items to toys and electronics. That’s nearly double the number of items it carries in its stores.

Next-day delivery, which will require a minimum order of $35, will be available in Phoenix, Arizona, and Las Vegas on Tuesday. In coming days, it will expand to southern California. The discounter plans to roll out the service to 75% of the U.S. population by year-end. It will also be adding hundreds of thousands more products as the program expands.

The announcement comes just two weeks after online behemoth Amazon said it’s upgrading its free shipping option to Prime members who pay $119 a year to one-day delivery from two-day delivery. Amazon has declined to say when the switch will happen, but it already offers one-day delivery for some items in certain areas.

Walmart says the new delivery program has been in the works for a while.

“Customer expectations continue to rise,” said Marc Lore, CEO of Walmart’s U.S. e-commerce division, told The Associated Press in a phone interview. “We’re trying to get ahead of that.”

The move will only increase pressure on other rivals that are already investing in millions of dollars to shorten the delivery window.

Amazon changed consumer expectations when it launched its two-day delivery for Prime members back in 2005 and forced other retailers to step up their game. But analysts say Amazon then needed to cut the delivery time in half to make its membership more attractive since others like Walmart offered free two-day deliveries without any membership.

Two years ago, Walmart began offering free two-day shipping on millions of items on its website for orders of at least $35. Target also offers free two-day shipping for those who spend at least $35 or use its RedCard loyalty card. Walmart has also been expanding same-day grocery delivery service fulfilled from its stores for a fee of about $10.

Lore says it will be cheaper for the company to do next-day delivery versus two-day service because eligible items will come from a single fulfillment center located closest to the customer. This means orders will ship in one box, or in as few as possible, unlike two-day deliveries that come in multiple boxes from multiple locations. Walmart is also trying to limit costs by tailoring products based on what shoppers demand in the local markets. For example, sunscreen would be available all year for areas like Southern California and Phoenix.

Still, Walmart sells far fewer products than Amazon and its online U.S. sales are only a fraction of Amazon’s online global merchandise empire. Jason Goldberg, chief commerce strategy officer of Publicis Communications, noted Walmart isn’t going to be able to ship the same number of products as Amazon under one-day shipping and its profit margins could get further squeezed as it focuses on the most popular items that would be subject to pricing wars.

Amazon has also been delivering more packages itself rather than relying on the post office and other carriers like UPS and FedEx. The company expects to spend $800 million in the second quarter to speed up deliveries and has expanded its fleet of jets. On Monday, it announced that it will be expanding an incentive program to its employees so they can quit their jobs and start their own Amazon package delivery businesses.

Walmart has one big advantage over Amazon — its more than 4,700 stores.

Walmart and Target have been turning their physical stores into shipping hubs, speeding up deliveries and helping to defray costs for services like curbside delivery and in-store pickup. Walmart has also been expanding the use of robots in its stores, which keep tabs on what’s on and not on the shelves. Meanwhile, Target has redesigned its staging area for packages to help speed up fulfilling curbside deliveries.

OMAHA, Neb. (AP) – A 20-year-old man has been imprisoned for crashing into a car and killing the woman driving it along an Omaha freeway.

Douglas County District Court records say Vismar Carmona-Martinez was sentenced Monday to 10 to 11 years in prison and credited for 498 days already served in custody. He’d pleaded no contest in March to felony vehicular homicide.

Prosecutors say Carmona-Martinez’s car rear-ended another car around 12:30 a.m. Jan 1, 2018. The driver of the car he hit, 67-year-old Ann Smock, died at an Omaha hospital.

Police say Carmona-Martinez’s blood alcohol content was three times the legal limit to drive. Prosecutors also say Carmona-Martinez is in the country illegally.

GARLAND, Neb. (AP) — Authorities say a sport utility vehicle passenger died after a collision in eastern Nebraska’s Seward County.

The collision occurred around 3:50 p.m. Sunday, about a mile (2 kilometers) south of Garland. The Seward County Sheriff’s Office says a westbound vehicle didn’t halt at a stop sign and struck the northbound SUV, fatally injuring the SUV passenger.

She’s been identified as 56-year-old Lily Gonzalez, who lived in Seward. The SUV driver’s been identified as 53-year-old Edward Gonzalez. He was treated at a Seward hospital and released.

The other driver’s been identified as 20-year-old Paxton Minnig, of Lincoln. He was taken to a Lincoln hospital.

Investigators say criminal charges are pending.

SOUTH SIOUX CITY, Neb. (AP) – The Dakota County attorney has released names and other details about an officer-involved shooting.

County Attorney Kim Watson said in a news release Monday that Luis Quinones Rosa died at a hospital early Saturday morning after exchanging gunshots with South Sioux City Officer Brian Van Berkum.

Watson says Van Berkum confronted Rosa because he matched the description of a man who’d been seen with a gun in a South Sioux City bar. Watson says Rosa shot first at Van Berkum, striking him in a leg and in the abdomen.

Watson says Van Berkum then returned the fire, hitting one of Rosa’s legs. Rosa was found unresponsive later in a nearby vehicle and taken to the hospital, where he died.

Van Berkum is recovering from surgery.
