The eldest daughter of one of Mexico’s most notorious drug lords has quietly purchased a home in a quiet Southern California suburb — leaving neighbors puzzled by the sudden arrival of a woman with deep cartel ties and seemingly unlimited money for renovations.

Jessica Johana Oseguera Gonzalez, 39 — known as “La Negra” and the daughter of the powerful cartel leader known as “El Mencho” — bought a five-bedroom home in Winchester, California, in September 2023.

Public records show the house sold for about $590,000, and neighbors say the purchase was made entirely in cash roughly 18 months after Oseguera Gonzalez was released from federal prison.

Her arrival in the normally quiet Riverside County cul-de-sac quickly drew attention from longtime residents, particularly an elderly couple who live next door.

Dan Watschke, 85, said he and his wife Nancy moved into their home just days after Oseguera Gonzalez bought the property.

“We’ve always thought something unusual was going on there,” Dan told reporters.

The home itself was newly built when Oseguera Gonzalez purchased it, but neighbors say the property was almost immediately torn apart and upgraded with expensive renovations.

According to Dan Watschke, contractors gutted the kitchen and bathrooms, removing cabinetry and installing high-end marble finishes and luxury appliances.

The landscaping overhaul was equally dramatic.

At one point, a crane was used to lift trees over the roof and drop them into the backyard as part of a major redesign.

“They put in a putting green and a pool and spa in the backyard,” Dan said.

The extensive upgrades appeared to cost tens of thousands of dollars.

“I always thought she must have an unlimited bank account because of the money going into that house,” he said.

Despite the costly renovations, the home often appears empty.

Neighbors say they frequently see cars — sometimes expensive models — coming and going from the driveway, yet rarely see anyone actually living in the home.

“What has always been very strange is that I never see anybody there,” Dan said. “I see cars coming and going all the time, but I never see anybody actually living there.”

Nancy Watschke said the woman introduced herself as a single mother with two daughters shortly after moving in.

“She told us she paid cash for the house,” Nancy said.

But over time, the couple began noticing unusual patterns around the property.

Vehicles with Mexican license plates occasionally appeared in the driveway, including one recent sighting of a Mini Cooper Countryman with Baja California plates.

Nancy said some cars remained parked at the house for days or even weeks before disappearing again.

“Sometimes cars would be there for two or three days and then they would be gone again,” she said.

Other visits have raised even more questions.

Nancy recalled seeing U-Haul trucks pull into the driveway and back into the garage before leaving again shortly afterward.

“At one point I thought maybe she was bringing illegals over — people coming in and out being paid,” Nancy said. “I didn’t know exactly what was going on, but something seemed off.”

Despite the suspicions, the neighbors said Oseguera Gonzalez herself has always been polite.

“She’s always been pleasant with us,” Dan said, recalling how she once helped him unload an outdoor refrigerator from a truck.

But sightings of her have become increasingly rare.

“I haven’t seen her this year,” Nancy said.

Oseguera Gonzalez previously served about 25 months in federal prison after pleading guilty to five counts of money laundering.

Prosecutors said she violated the U.S. Foreign Narcotics Kingpin Act by conducting business with companies linked to her father’s powerful Jalisco New Generation Cartel.

Authorities alleged she helped funnel profits from fentanyl, cocaine and other drug sales into legitimate-looking businesses in Mexico, including bars, sushi restaurants and a tequila brand.

Her family’s ties to organized crime run deep.

Her estranged husband, Julio Alberto Castillo Rodriguez, is believed to be a high-ranking cartel figure rumored to be in line for leadership after the death of El Mencho.
