Just last week, Thomas J. Hughes, a 29-year-old banker at Moelis & Company, was found dead with drugs in his system after falling from a building in Manhattan.

“The only explanation is that I know he’s been working very hard and has been under a lot of pressure,” Mr. Hughes’s father told The Daily Mail. “His work did not leave much time for enjoyment, but that’s the nature of the assignment that he chose.” An investigation is pending to determine the official cause of death.

For more than a month, Mr. Gupta’s death has largely remained held in confidence among a small group of his colleagues and family. After Mr. Gupta’s death, David Solomon, Goldman’s co-head of investment banking, and John S. Weinberg, a vice chairman, flew to San Francisco to speak with a small group of the bank’s employees and discuss the firm’s approach to work-life balance. The firm held a small memorial service for Mr. Gupta, who was universally liked by his colleagues and whom several said was so good at his job that he had become one of the “go-to” analysts. Indeed, his proficiency and work ethic appear to have led to him to take on a large workload.

“We are saddened by Sav’s death and feel deeply for his family,” Goldman said in a statement. “We hope that people will respect the family’s expressed desire for privacy during this difficult time.” Mr. Gupta’s father wrote an essay about his son’s death, which he posted on Medium and later removed. In an email, Mr. Gupta’s father said, “At this time, the grieving family does not wish to speak to the press.” He said his essay about his son was intended for “the grieving family and a means of dealing with my deep anguish and catharsis.”

Of course, it is always difficult to directly link a death or possible suicide to work conditions. Other factors can be in play, like family problems, medical issues or a history of depression. And in Mr. Gupta’s case, the cause of his death remains undetermined.

Still, the string of deaths on Wall Street appears to rise above the level of simple coincidence. Last February, Fortune ran an article titled: “Is there a suicide contagion on Wall Street?”

Studies have suggested that financial service employees are at higher risk than those in many other industries. According to the National Occupational Mortality Surveillance, individuals who work in financial services are 1.5 times more likely to commit suicide than the national average. The highest suicide rates in the United States are among doctors, dentists and veterinarians.
