On February 23, 2026, reports confirmed that Nemesio Rubén Oseguera Cervantes, widely known as El Mencho, was killed during a Mexican military operation. He was the longtime leader of the Jalisco New Generation Cartel (CJNG), one of Mexico's most powerful criminal organisations.

Following the operation, unrest was reported across parts of Mexico, including vehicle burnings and highway blockades — tactics historically associated with CJNG when responding to major security actions.

El Mencho Net Worth: How Rich Was He?

There is no verified audited figure confirming El Mencho's exact personal net worth.

However:

  • In 2019, a US DEA agent publicly estimated that El Mencho's wealth could be at least $500 million and potentially exceed $1 billion.
  • These figures were estimates based on intelligence assessments, not financial disclosures.
  • Some broader cartel-level estimates have placed CJNG's total network value in the tens of billions, but these are speculative and reflect organisational scale rather than personal assets.

Because CJNG operated in illegal drug trafficking, money laundering, and international smuggling, calculating precise wealth is nearly impossible. Under El Mencho's leadership, CJNG became:

  • A major supplier of cocaine to the United States
  • A key producer and trafficker of fentanyl
  • A dominant force in methamphetamine distribution

US authorities had also placed one of the largest bounties ever offered on a Mexican drug lord for information leading to his capture.

Who Is Rosalinda González Valencia?

El Mencho was married to Rosalinda González Valencia, who is linked to the powerful Valencia crime family, also known as Los Cuinis.

Key facts:

  • The couple reportedly married in 1996.
  • Reports indicate they were legally separated in 2018, though this did not necessarily mean a complete personal break.
  • Rosalinda was arrested multiple times on allegations related to money laundering.
  • Authorities have described Los Cuinis as handling financial operations connected to CJNG.

Her alleged financial role was considered critical to maintaining the cartel's economic infrastructure.

El Mencho's Children: Who Are They?

El Mencho and Rosalinda González Valencia have three known children:

1. Rubén Oseguera González ('El Menchito')

Rubén Oseguera González, known as El Menchito, was once considered a key figure inside CJNG.

  • He was arrested and later extradited to the United States.
  • He was convicted on drug trafficking and weapons charges.
  • He received a life sentence in US federal court.
  • Before his arrest, he was widely viewed as a potential successor.

2. Jessica Johanna Oseguera González ('La Negra')

Jessica Johanna Oseguera González was accused of managing businesses allegedly linked to her father's network.

  • She pleaded guilty in the US in 2021 to financial transactions involving CJNG-related enterprises.
  • She was sentenced to federal prison.
  • The businesses reportedly included restaurant and tequila-related ventures.

3. Laisha Oseguera

Laisha Oseguera has also drawn law enforcement scrutiny.

  • In 2021, reports indicated that she and her partner were sought after two Mexican navy personnel were kidnapped.
  • Authorities believed the kidnappings may have been retaliation following Rosalinda's arrest.
  • No confirmed conviction has publicly established her role within cartel leadership.

Could the Children Take Over CJNG?

There is currently no officially confirmed successor to El Mencho. However, several factors shape the likely succession dynamics. El Menchito is serving a life sentence in the United States, effectively removing him from any leadership race. Jessica Johanna has already faced legal prosecution, limiting her potential role, while Laisha remains under investigation and has not been confirmed as a cartel leader. Because of this, security analysts believe leadership is more likely to shift to senior cartel lieutenants rather than immediate family members.

Historically, when major cartel bosses are killed or captured, their organisations tend to fragment in the short term before eventually consolidating under new leadership.
