OMAHA, Neb. (AP) — Hopes by small aviation museum in southwestern Iowa that a stamp in its possession was rare enough to parlay a potential fortune crashed Friday when experts told them it wasn’t real, and likely not even worth the paper it was glued upon. The Iowa Aviation Museum in Greenfield, Iowa, had what it thought was an “Inverted Jenny” stamp on display for some 20 years. After bringing it to Omaha, they learned it wasn’t authentic.

LYNNVILLE, Iowa (AP) — Authorities in central Iowa have confirmed the death of a 19-year-old man in a grain bin. Television station KCCI reports that Mahaska County Sheriff’s deputies were called to the grain bin in Lynnville before 8 a.m. Friday. Officials say Benjamin Raymond Van Wyk died at the scene after becoming entangled in the grain bin’s auger.

IOWA CITY, Iowa (AP) — A board has ordered the reinstatement of an Iowa employee who was fired in 2017 after sending sexual text messages, including a photo of a penis, to a saleswoman for a state vendor. The decision puts taxpayers on the hook for nearly two years of back pay and benefits for Nicholas Carnes, a power plant engineer at the Glenwood Resource Center. The Public Employment Relations Board agreed with a judge that Carnes’ misconduct didn’t warrant termination but a 10-day suspension instead.

DAVENPORT, Iowa (AP) — A Bettendorf man charged in connection with the overdose death of another man has been given three years of probation. The Quad-City Times reports that Michael Spencer also was granted a deferred judgment. A deferred judgment allows Spencer’s conviction to be removed from court records if he fulfills his probation terms. Prosecutors say 23-year-old Tyler Ekstrand overdosed on heroin that Spencer provided him.

SIOUX FALLS, S.D. (AP) — The South Dakota chapter of the American Civil Liberties Union says it’s concerned about a report that the U.S. military is using high-altitude balloons to conduct surveillance tests in six Midwestern states.

The Guardian reports that up to 25 balloons are being launched from South Dakota, and will drift through parts of Minnesota, Iowa, Wisconsin, Missouri and Illinois. The Guardian examined filings with the Federal Communications Commission, which say the balloons are meant to provide persistent surveillance to locate drug trafficking and homeland security threats.

According to KELO, the ACLU says this kind of constant surveillance violates the privacy of citizens, creating what’s a pervasive checkpoint over cities. The ACLU says the military needs to be clear about information it’s collecting.

A spokesman with the U.S. military didn’t immediately respond to an email from The Associated Press.

A Creston man suffered suspected serious/unknown injuries following a rollover accident in Union County at around 11:50-p.m., Wednesday. The Union County Sheriff’s Office said Friday, 28-year old Quinton Lee Kimball was driving a 2015 Buick Enclave SUV eastbound on 140th Street, near the Green Valley Lake Dam, when he swerved to miss a deer on the road.

The SUV went out of control and entered the south ditch and eventually traversed a walking trail before hitting a power pole and rolling onto its top. Kimball was found by an Alliant Energy worker, who transported him to the Greater Regional Medical Center, in Creston.

Damage to the SUV was estimated at $16,500, while damage to the power pole was estimated at $1,500. Kimball was cited for having no insurance.

The Union County Sheriff’s Office says a Creston man reported on Monday that his 2014 camouflage colored Yamaha 450 ATV had been stolen. The ATV was taken from the man’s property in Afton. It was valued at $3,500.
