The Los Angeles mansion where authorities uncovered more than a thousand guns after getting an anonymous tip belongs to oil heir Gordon Getty’s ex-mistress, according to a report Thursday.

It’s still unclear what, if any, connection Cynthia Beck has to Wednesday’s 12-hour raid, which resulted in the seizure of a trove of firearms, including rifles, shotguns, assault weapons and pistols.

The local real estate mogul’s secret relationship with the fourth son of oil scion J. Paul Getty grabbed headlines in the late 1990s, when it was revealed that the pair had three young daughters together. Getty was a married father of four at the time.

In more recent years, Beck has acquired multiple properties in Los Angeles and San Francisco, so it’s unclear if she lived at the sprawling Bel Air home, the Los Angeles Times reported.

Some of her properties are co-owned with a licensed general building contractor named Girard Saenz, who was in the home at the time of the raid, the newspaper said.

Saenz was arrested on suspicion of violating California’s law banning the manufacture, distribution, transportation and importation of assault rifles or .50-caliber weapons.

Authorities say Saenz was selling the guns found in the mansion. He was released from jail Thursday on $50,000 bond.
