Hard-working Rhonda Knutson, 22, was murdered on Labor Day 1992.

Labor Day of 1992 proved deadly for a hard-working young Iowa woman, the very type the holiday was created to honor.

When she was murdered early Monday, September 7, 1992, Rhonda Knutson was at the center of a perfect combination of danger factors.

The 22-year-old woman worked alone overnight in a Phillips 66 Convenience Store on Highway 63 six miles south of New Hampton in Chickasaw County.

That Labor Day weekend, thousands of vehicles passed by on the major north-south artery during one of the busiest travel times in the year.

Convenience stores like the one where Rhonda worked provide a welcoming oasis for leg-stretching, calls of nature, jolts of caffeine, beer, cigarettes, gas, and snacks.

Customers come in. Customers leave. It’s a never-ending parade of travelers of all ages and personalities and destinations.

At night, the convenience store can be Ernest Hemingway’s “clean well-lighted place,” offering the lonely a round-the-clock haven where a pot of coffee is always brewing and someone is behind the counter to listen.

In fact, an insomniac area farmer regularly came in the middle of the night to chat with Rhonda.

But a convenience store, with a nearby highway providing quick escape, can also be the ideal target for robbery committed quickly and efficiently. Or the assault or murder of the clerk, who is usually alone.

What sort of person stopped early in the morning at the New Hampton Phillips 66 Convenience Store on Labor Day 1992?

Whatever the original motive, the result was that Rhonda was taken to a back room and bludgeoned to death. There was no sexual assault or robbery.

Customers saw a man who looked like this sketch on the night Rhonda was murdered.

Customers said two truck drivers caught their attention. Both were heavy-set, dark-haired, white males between 35 and 45. One was clean-shaven and drove an unknown vehicle. The other had a beard and moustache and was thought to be driving a conventional tractor pulling a white/silver trailer.

Rhonda was not wary of truckers. Her dad was one, so she enjoyed hearing about their rigs, destinations, and cargoes. That lack of caution might have proved deadly if one of these men was involved in her death.

Intense investigation, searches of regional truck stops, posters, rewards, plans to air the case on “America’s Most Wanted,” and use of psychics have not resulted in answers for Rhonda’s death.

Her long-time, live-in boyfriend Al Wolf was not a suspect; and the Chickasaw County Sheriff investigated and quelled rumors that county deputies were involved.

Any suspect authorities are left with was probably a stranger who came into the store during the night.

Rhonda’s large and caring family and her friends need answers for this brutal crime.
