At midday on December 13, 2009, Steven Koecher (born November 1, 1979) parked at the end of a cul-de-sac in the Anthem neighborhood of Henderson, Nevada, United States and got out of his car, an action recorded on a nearby home's security camera. After returning shortly afterwards, he retrieved something from the vehicle and walked away, with another security camera capturing his reflection in a car window. Koecher has not been seen since, although some activity was recorded on his cell phone over the next two days.Koecher's absence from his home, work, and church activities in St. George, Utah, was not noted for several days; eventually, the homeowners' association of Anthem, where he had parked, got in touch with his employer and then his parents about the abandoned car, at which time he was reported missing. Police had few leads at first, since it appeared he had intended to return to Utah and did not appear to be involved in any criminal activities. The reason for his trip to the Las Vegas area that day has never been determined; his family believes he was looking for work since he could not make the full rent payments on his apartment with the job he had. Searches in the area around where he was last seen yielded no evidence. Further investigation found credit card and cell phone receipts and witness statements showing that in the week prior to his disappearance, Koecher had been driving great distances around Utah and Nevada, including almost 1,100 miles (1,800 km) in one day. The purpose of these trips is also unknown; on one he stopped to visit a former girlfriend's parents and had lunch at their house.Joshua Powell, a West Valley City man suspected of murder in the disappearance of his wife Susan Powell – which took place a week before Koecher's – argued along with his father and brother that the two cases were related, suggesting the two were romantically involved and had run off together. Both Susan's family and Koecher's have dismissed that theory. The Koecher case has been the subject of an episode of the Investigation Discovery channel's Disappeared series.

The Wendy's 3-Tour Challenge was an unofficial golf event held in November at the Rio Secco Golf Club in Henderson, Nevada. The tournament was a unique stroke play event, and, as the name suggests, pitted three teams, with three members per team, from the PGA Tour, the LPGA Tour, and the Champions Tour (known as the Senior PGA Tour prior to 2001) against each other. The 2013 purse was $1 million.The challenge event was done in one day, over 18 holes, and is usually held on a Tuesday. It was preceded by an amateur tournament and a one-day pro-am tournament. The event was handicapped to provide all competitors a fair and equal chance of succeeding. The PGA Tour players played the course at its full length, while the Champions Tour players hit from tee positions that made the course shorter and the LPGA players from even shorter tee positions. The event supported the Dave Thomas Foundation for Adoption, a charity established by the founder of Wendy's, the fast food restaurant that sponsored the tournament. In 2013, the tournament raised a record $4.1 million, and, since it was founded in 1992, it raised more than $50 million overall for the charity.ABC televised the event until 2009, showing the tournament tape-delayed on a weekend in December just before Christmas, with the first nine holes broadcast on Saturday, and the final nine holes on Sunday. Terry Gannon did the on-air play-by-play. From 2010 to 2013, the event aired on the Golf Channel.
