Neighbors blow the lid off mysterious activity at California mansion of the daughter of ‘El Mencho’: ‘Unlimited bank account’

The eldest daughter of “El Mencho” quietly snapped up a suburban California home after serving time for laundering drug money — and baffled neighbors say she’s had no shortage of cash to renovate the place.

They say strange cars — some bearing Mexican license plates — appear and disappear from the property while mysterious visitors come and go.

Jessica Johana Oseguera Gonzalez, 39 — known as “La Negra” — purchased a newly built five-bedroom house in Winchester, Southern California, for $590,000 in September 2023. She apparently paid cash for the property about 18 months after being released from federal prison. Her presence has left neighbors in the normally quiet cul-de-sac feeling deeply uneasy.

“We’ve always thought something unusual was going on there,” neighbor Dan Watschke, 85, told The Post.

Watschke and his wife Nancy moved into the house next door on Oct. 1, 2023 — just days after Oseguera Gonzalez bought the property.

“She obviously had money to spend — a lot of money,” Dan said. “These are brand-new homes, but from what I understand she basically gutted it.”

Contractors tore out cabinetry in the kitchen and bathrooms and replaced them with marble and high-end appliances, he said. A crane even lifted trees over the roof and into the backyard as part of an extensive landscaping overhaul.

“They put in a putting green and a pool and spa in the backyard,” Watschke said. “I always thought she must have an unlimited bank account because of the money going into that house.”

The improvements ran into the tens of thousands of dollars, according to the neighbors. But despite the lavish upgrades, the home often appears empty.

“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, also 85, said the woman who introduced herself as a single mother with two daughters told them she paid cash for the house.

“She said she was a mother with two grown daughters,” Nancy said. “She told us she paid cash for the house.”

Still, the neighbors quickly felt something wasn’t right.

“From the beginning we felt something wasn’t right about that house,” Nancy said.

Cars — sometimes expensive models — are often left parked at the property for days or even weeks without anyone appearing to stay there, she said.

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

On one recent visit, a Mini Cooper Countryman with Baja California plates was sitting in the driveway. Other vehicles with Mexican plates have appeared there in the past.

The comings and goings have fueled suspicions among the elderly couple.

“There have been occasions where a U-Haul backed up into the garage and they were either dropping stuff off or picking stuff up,” Nancy said.

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

Despite their concerns, they say Oseguera Gonzalez herself has always been polite.

“She’s always been pleasant with us,” Dan said. “She helped me once when I bought an outdoor refrigerator. I’m 85 years old and she helped the neighbor and me take it off the truck.”

But sightings of her have been rare.

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

Oseguera Gonzalez served roughly 25 months behind bars after pleading guilty in the United States to five counts of money laundering. Prosecutors said she violated the US Foreign Narcotics Kingpin Act by conducting business with companies linked to her father’s notorious Jalisco New Generation Cartel

Authorities said she helped funnel proceeds from fentanyl, cocaine and other drug sales into businesses she operated in Mexico — including bars and sushi restaurants in Jalisco, Puerto Vallarta and Guadalajara, as well as a tequila brand called Onze Black.

A dual US-Mexican citizen born in San Francisco, she was released from prison in March 2022.

Her estranged husband, Julio Alberto Castillo Rodriguez, is believed to be a high-ranking member of the cartel and has been rumored to be in line to take over leadership following the death of El Mencho.

The Winchester property in Riverside County sits just 12 miles from a café in Perris run by Oseguera Gonzalez’s younger sister, Laisha Oseguera Gonzalez, 24.

Customers say the café has a friendly neighborhood vibe and many were stunned to learn it was linked to the family of one of Mexico’s most notorious drug lords.

“It’s a normal place, and she’s really nice,” one regular previously told The Post. “Something like the cartel would never cross people’s minds.”

Laisha has also kept a low profile despite the dramatic story surrounding her family.

Her husband, Cristian Gutierrez-Ochoa — known as “El Gaucho” — is a suspected cartel lieutenant who allegedly faked his death in Mexico before resurfacing in California under a false identity.

Authorities say he later purchased a $1.2 million Riverside home in cash and was eventually arrested in 2024 for trafficking cocaine and methamphetamine into the US and laundering millions in drug proceeds. He was sentenced to 11 years in prison last year.

Meanwhile, cartel violence triggered by El Mencho’s death has reportedly left dozens dead across Mexico.
