In recognition of the Gaucho Grill Argentine Steakhouse () Grand Opening in the First National Bank of Temecula building (The Bank), I want to share information that I have collected over the past 25 years. There is so much available to share that it will take several posts in the coming weeks.

THE TEMECULA BANK ROBBERY - It actually happened thirty-seven years ago!
by Sam Hicks
THURSDAY, AUGUST 14, 1930, brought an interesting collection of newspaper stories to sun-drenched, sleepy Temecula, a usually quiet little ranch town near the Riverside-San Diego county line. Ed Howard, lifelong resident of the Temecula Valley who works at Murrieta Hot Springs, clipped these news reports and kept them for over thirty years before he recently gave them to me.
From the Elsinore paper came this headline and lead paragraph: "TEMECULA BANK ROBBER CAUGHT! If you plan to rob a bank, don't choose Temecula. Inside of twenty minutes after the hold-up at the First National Bank of Temecula, yesterday, the doughty cashier, J. W. Chisholm, had the robber on the road to jail and the loot back in the bank, besides having frustrated the plans of the bandit, Michael 'Jerry' Diaz, to lock the bank employees in the vault. . . ."
From a Riverside newspaper came: "CASHIER OF TEMECULA BANK IS HERO OF DARING HOLD UP IN WHICH BANDIT IS NABBED. J. W. CHISHOLM TOO ALERT FOR MICHAEL DIAZ; CHASE RESULTS IN CAPTURE; MONEY RECOVERED. Matching his wits with a gunman who poked a revolver through a teller's grill and scooped up $1600 of the bank's funds, J. W. Chisholm, cashier of the Temecula First National Bank, yesterday proved a hero as he frustrated the bandit's attempt to lock the employees in a vault and later figured in a spectacular running gun battle that brought the robber into custody two miles from the scene of the holdup. . . ."
From a Los Angeles newspaper came: "TEMECULA BANK ROBBER CAUGHT. CASHIER AND RANCHER CAPTURE YOUNG BANDIT AND RECOVER $1200 HANDED OVER. First bank robbery in Riverside County in several years occurred Wednesday morning when Miguel Diaz, youthful Mexican, held up the Temecula bank and made his escape with $1200 in cash, only to be chased and captured on the highway near Murrieta Hot Springs. . . ."
From the Escondido paper: TEMECULA BANK ROBBED BUT ROBBER IS CAPTURED LATER. Chief of Police Andreasen received word Wednesday at noon that the Bank of Temecula was held up and robbed by two masked men at ten o'clock Wednesday morning and that he should be on the lookout for the robbers, who were traveling in a yellow Ford roadster. . . ."
THE TEMECULA BANK, facetiously referred to by local ranchers as "the pawn shop," opened for business at ten o'clock Wednesday morning, August 13, 1930. Miss Agnes Freeman, teller, recognized Miguel Diaz as he entered the bank about a half hour later. Miss Freeman knew Diaz well, as he had earlier worked under her father, then foreman of the Pauba Ranch (now Rancho California). Diaz carried with him a folded paper shopping bag.
Miss Freeman was about to greet Diaz when he whipped out either "a .38 special revolver" or a "nickel-plated .32-20 revolver"—take your pick—pointed it at the girl and ordered her to put up her hands. Miss Freeman obeyed.
Chisholm, who was in the rear of the room counting a consignment of money just received, stepped to the window and was also ordered to raise his hands. Diaz threatened to shoot them both if they gave him any trouble. He told Chisholm to give him the cash on the counter and then hand over the consignment money. Diaz sacked up the money and, waving his pistol, ordered Miss Freeman and Chisholm into the bank vault.
Chisholm had anticipated that some day his bank might be robbed, so he kept a handy screwdriver in the vault and a 7.65 Luger pistol in his desk. When Diaz slammed the vault door shut Chisholm already had his trusty screwdriver at work. He succeeded in jamming the door sufficiently to keep it from locking. Diaz fiddled nervously with the door for a few seconds trying to actuate the intricate lock system, gave up the idea and ran out of the bank with his sack full of money.
Diaz was driving a Model A Ford coupe with a canvas top, recently stolen from a man by the name of Dallas in Brawley. Diaz jumped into his get-away car—got it started—and left Temecula headed north.
Jack Chisholm, always thinking ahead about matters like due dates and screwdrivers, lost no time in pushing the vault door open and in scooping up his Luger. He dashed outside and fired a couple of parting shots in the general direction of Diaz's departure.
Rancher John McSweeney had just gotten himself comfortable in the barber chair in the shop across the street where the Temecula Post Office is now located. The barber had already applied a sea of foam to Mc-Sweeney's face. Either the barber's steaming towel, or the shots, or a combination of both, caused McSweeney to leap from the chair and dash headlong into the street. Through the lather his eyes focused on Chisholm, gun in hand.
Together they jumped into McSweeney's Buick and roared off in pursuit of the bandit's Ford. Rancher McSweeney and banker Chisholm saw Diaz turn off Highway 395 on Wi******er Road. As McSweeney speeded up and began overhauling the Diaz car, Chisholm crawled out on the running board and again opened fire with his Luger. Once more Chisholm's foresight proved extremely accurate and he put two shots through the back of the Ford, both of which should have hit Diaz but didn't. Then, just for good luck, Chisholm fired again and cursed his lack of foresight because that was his last shell.
But Diaz didn't know that. The sudden perforations appearing as if by magic in his windshield caused him to make a new decision. He pulled off the road in a cloud of dust, stopped and jumped to the ground, hands in the air, and surrendered. Chisholm relieved the robber of his shiny six-shooter and sack of money and ordered him into the McSweeney car. The banker then asked A. A. Barnett, a well driller working nearby, to drive Diaz's battle-scarred car back to Temecula.
Miguel Diaz, a roaming cowboy in his twenties who got his start in the wild country around Leadville, Colorado, and came to Temecula from Nevada, pleaded guilty to first degree robbery and was sentenced to prison for from five years to life. He had no former record, and his only explanation of his act was that he had hoped to use the money to enroll in a Los Angeles flying school.
Louie Roripaugh, head man at the Pauba Ranch where Diaz worked as a muleskinner, says that the young cowboy's dream of becoming an aviator probably never materialized. Diaz was paroled after serving about three years. A few years ago, on a trip to Imperial Valley, Roripaugh learned that for many years after his release Diaz had worked on the Walker ranch down in the Imperial—as a ranch hand, not as an aviator.
Al Knott, Temecula's blacksmith for a half century, recalls that after the capture of Diaz the bank's insurance company presented Chisholm with a nickel-plated .45 automatic pistol. Chisholm, proud of his gift, would bring the gun down to Al's shop on long summer evenings and the two men would test their skill, using targets set up against steel plates in the back of the shop.
THE FIRST NATIONAL BANK OF TEMECULA, during its long and useful life, survived many other crises through foresight. During the depression of the thirties its doors remained open for business as usual at all times except for the brief period of time when all banks were ordered closed by the federal government.
The bank remained strong and solvent until the early forties when a new manager began loaning large sums of money to an outside prospector who was a close and trusted friend. The friendly prospector returned periodically to the Temecula bank with reports that his endeavors in the field were just about ready to pay off in huge dividends. However, in the meantime, he needed just a few thousand dollars more to expedite cashing in on his bonanza.
But it was too late. The bank manager had apparently overstepped his bounds. The directors closed the bank.
