The Duggan Crime Family is a corrupt family of Texan petrochemical magnates in Grand Theft Auto Online. They were led by Avery Duggan, a Texan businessmen and private military CEO, until his death in 2019 upon which his nephew, Thornton Duggan, assumes leadership.

Events of GTA Online

In 2019, the Duggan Crime Family, mostly made up of hired Professionals, seeks to buy The Diamond Casino & Resort from its owner, Tao Cheng, a member of the Cheng Family Holdings, but first needs it to be destroyed to reduce the property value and enable them to buy everything at rock-bottom price.

When the family accepts to meet with Tao, the meeting goes sour, and Avery orders his henchmen to kill Tao, triggering a war between the Duggan Family and the Cheng Family Holdings, which leads to the destruction of Avery's assets and the assault of the Diamond Casino & Resort, which is then repelled by the protagonists.

Later on, Thornton, growing tired of Avery risking the destruction of the crime family, betrays him and hires associates of Tao Cheng to kill his uncle. He also wants to purchase the casino for his own personal gain, which also benefits most of the current Diamond staff, as it would mean they would keep their jobs.

After Avery's death, the Duggan Crime Family had largely collapsed, with the few remaining members uniting behind Thornton and working as security staff at the Diamond, replacing Vincent and the old security team. They are further damaged by the events of The Diamond Casino Heist, which leads to numerous security shipments being destroyed, dozens of guards getting killed, and a significant amount of money being stolen from the casino.
