The December heist may not have been as high-tech as “The Thomas Crown Affair” or “Ocean’s Eleven,” but it was clearly well-planned.

One or more burglars, armed with drills, entered the secured hallway of the Artesian Springs Apartments in Millcreek from the multilevel parking garage in the middle of the night. The target? Storage units that line up outside the various apartments.

First, the thieves punched holes around the dead bolts to disable the lock and gain access to the closets. A couple of the units were empty, but one contained several unexpected treasures worth thousands of dollars. So they hauled off the booty, some of it large and hefty.

For the sleeping owner, Judith Mehr, that’s when it became “The Nightmare Before Christmas.”

On Dec. 15, Mehr, a professional artist, hosted a dinner party for friends, and needed to retrieve several folding chairs from her nearby locker. Two days later, however, when she went to return them, she discovered the broken lock and break-in.

Among the missing items were some camping equipment and — to her horror — two of her largest paintings, the 3½-foot-by-2½-foot “Thundercloud Upheaval at Dove Creek” and the even bigger 6-foot-by-3-foot “Water Protectors at Standing Rock Dec 6, 2016.”

Both were framed, heavy and tough to carry, she says, and together were assessed at $20,000.

She felt “invaded and totally powerless,” Mehr says. “My babies have been violated. OK, they’re just paintings, but they are my paintings.”

Art, after all, is her life.

After earning a degree in art from Brigham Young University in the early 1970s, Mehr has made her living as a painter and an illustrator.

Starting in 1978 and continuing through the early 2000s, Mehr was commissioned by The Church of Jesus Christ of Latter-day Saints to produce works such as the giant mural in the faith’s Family History Library on West Temple titled, “The Eternal Family Through Christ.” She also painted portraits of church Presidents Spencer W. Kimball, Howard W. Hunter and Gordon B. Hinckley that hang in the adjacent Church History Museum, and provided numerous illustrations for Latter-day Saint magazines.

Naturally, she was distraught by the December theft.

Enter Unified Police Detective Jordan Schmidt.

The patient police officer took down all the information about the stolen art, titles and size and advised Mehr to keep checking with pawnshops, Craigslist and other potential outlets for pilfered canvases.

Schmidt then produced a full report, he says, and “sent it out to with photos to all police agencies in the state.”

But Schmidt could not be too encouraging. Investigating property theft can be daunting, and goods are rarely recovered.

“It takes,” he says, “sheer luck.”

(Leah Hogsten | The Salt Lake Tribune) Judith Mehr says she was stunned when police officers contacted her to tell her one of her two paintings that were stolen in December had been recovered. Here she is reunited with her “Thundercloud Upheaval at Dove Creek.”

Meanwhile, Cottonwood Heights Detective Kenyon Kawa was looking into a different case — a stolen wedding ring. And he had a lead on a suspect, who tipsters thought might have it.

Before the officer could question the man, though, the suspect was shot to death by a Murray homeowner during an apparent attempted burglary.

Undeterred in looking for the ring, Kawa reached out to the dead man’s relatives, who let him into the suspect’s apartment more than a half-hour away from where he died.

Spying no jewelry in the apartment’s main space, the officer stepped into the man’s bedroom.

There, leaning against the wall, in the nearly empty space, was a large painting that seemed, Kawa recalls, “out of place.”

He turned it over and spied Mehr’s name, the “Thundercloud” title and its assessed value.

When Kawa called an excited Schmidt about his discovery, the Millcreek detective exclaimed, “We’re gonna need a truck.”

At the end of the two caper movies, [spoiler alert] both Thomas Crown and Danny Ocean get away with their crimes, though Crown does return the stolen masterpieces before jetting out of sight.

In this Utah case of purloined paintings, both Schmidt and Kawa hope life does not imitate art.

As long as “Standing Rock” is at large, they want to catch the thief or thieves — not necessarily the same as the deceased suspect — and return the “baby” to its creator.

“I’m gonna keep digging, Kawa says, “until all the leads are in.”

The detective, who found the missing wedding ring in Texas, remains undaunted.
