The 31-year-old son of former New Jersey Gov. Jon Corzine has died, a spokesman for the family confirmed Thursday afternoon.
His family, through a spokesman, said the cause of death was suicide brought on by "severe depression."
"The Corzine family expresses its sincere appreciation for the kind thoughts and expressions of sympathy they have received from friends and many others," Corzine family spokesman Steven Goldberg said in a statement to NBC News. "The family is planning a small, private memorial service, and they ask that people respect their privacy during this difficult time as they mourn the loss of Jeffrey.
Golberg added that Jeffery Corzine "had been suffering from severe depression for several years and recently had been receiving treatment for what is a very painful and debilitating physical and mental ailment.
"On Tuesday morning, he succumbed to his disease and made the tragic decision to take his own life."
Jon Corzine served as the Democratic governor of New Jersey from 2006 to 2010, after six years in the U.S. Senate. He went on to run financial firm MF Global but resigned in 2011 after it went bankrupt.
One of three children, Jeffrey Corzine attended New York University.
His father's successor, Gov. Chris Christie, tweeted his condolences.
