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.
