OMAHA, Neb. (AP) — TD Ameritrade’s new headquarters tower in Omaha has been recognized for its efficient design that includes numerous features to conserve energy.

The $250 million, 12-story tower opened last year in west Omaha. TD Ameritrade said Tuesday the U.S. Green Building Council gave the building its highest platinum rating for Leadership in Energy and Environmental Design.

The building includes sensors to turn off LED lighting when workers aren’t at their desk or if sunlight is available, and rainwater is captured and reused in toilets.

There are also solar panels on the tower’s roof, a rooftop garden on another part of the building and four wind turbines.

TD Ameritrade officials say the environmental features cost more up front, but they will pay off over time because the building uses significantly less energy.

OMAHA, Neb. (AP) — Mechanics have been checking an American Airlines jet that made a precautionary landing in Omaha after crew members reported what smelled like an electrical fire in the cockpit.

The Dallas-bound jet took off from Omaha just before 6:30 p.m. Monday but soon turned around and landed back at Eppley Airfield.

American spokesman Matt Miller told The Associated Press on Tuesday that Flight 2323 carried 62 passengers and five crew members. Miller says a replacement for the MD-80 aircraft took off about 9:30 p.m. and made it to Dallas without incident.

Miller says he had no word yet on what, if anything, was wrong with the flight’s original plane.

OMAHA, Neb. (AP) — A judge has ordered a man convicted of killing four Omaha people last summer to a state psychiatric hospital for treatment in an effort to restore his mental competency to undergo sentencing.

The decision came Tuesday in a brief hearing before Douglas County District Judge Peter Bataillon held after the judge found earlier this month that Nikko Jenkins was not mentally fit enough for a sentencing hearing.

Jenkins pleaded guilty and was convicted in April of four counts of first-degree murder for the August 2013 shotgun deaths of Curtis Bradford, Jorge (HOR-hay) Cajiga-Ruiz (cah-HE-gah ROO-ez), Juan (WAN) Uribe-Pena (oo-REE-bay PE-nyah) and Andrea Kruger in separate attacks.

Public defender Tom Riley and Douglas County prosecutor Don Kleine both agreed that Jenkins should be sent to the Lincoln Regional Center.

LINCOLN, Neb. (AP) — An evaluation survey conducted by the Nebraska State Bar Association has given passing grades to all but two of Nebraska’s 137 judges.

19 percent of active bar association members who live in Nebraska, Council Bluffs and Sioux City, Iowa, and Yankton, South Dakota, completed the electronic survey.

Association President G. Michael Fenner says the 2014 Judicial Performance Evaluation isn’t an absolute measure but says it lets attorneys evaluate judges on a variety of criteria.

This year the lawyers gave passing grades to 94 percent of the state’s judges. The only two with retention ratings below 50 percent were Douglas County Judge Darryl Lowe and Douglas County Juvenile Judge Elizabeth Crnkovich (SUR’-koh-vihtch). They didn’t immediately return messages left by The Associated Press on Tuesday.

GRAND ISLAND, Neb. (AP) — Nebraska fire crews have extinguished a Union Pacific train that caught fire and temporarily closed a highway.

The eastbound train ignited on Monday evening northeast of Grand Island.

The city’s fire chief says a cooling fan in the engine is what caught fire. It’s unclear why.

The chief says firefighters had to use dry chemical extinguishers to put out the fire. No injuries were reported.

U.S. Highway 30 was closed for about 20 minutes so the fire crews could stabilize the train.
