Green Beret turned Bank of America banker Leo Lukenas died just a year into a grueling investment job 'where associates work 100 hours a week'

A former Green Beret died just a year after a grueling job at Bank of America, where employees say working 100 hours a week leaves them feeling ill.

Leo Lukenas III, 35, in New York City on Thursday of 'acute coronary thrombus, – a disease that causes the formation of a blood clot in a blood vessel of the heart.

The father of two and former Army Special Forces member turned to banking last summer in an effort to “pursue new opportunities for his family,” his loved ones said.

The Brooklyn native had reportedly recently worked on UMB's acquisition of Heartland Financial USA, Inc.

But while his death was officially attributed to “natural causes,” it has led to claims from Wall Street workers who say conditions in the industry are intolerable, especially when it comes to ironing out a major problem.

Current and former investment bankers told the story Business insider that Lukena's death has raised concerns within BoA and especially among the lower ranks.

A junior banker at BoA said of Lukenas' death: 'I think what we would all like is some recognition of what happened, and at least not completely ignore the fact that it could be work-related.

“And to at least just have conversations about how they can make the working lives of junior bankers much better, because that's long overdue. And if anything, I believe it has gotten worse.”

Lukenas was part of the Financial Institutions Group (FIG) team that advises bank clients on deals, according to a source familiar with the situation.

Insider told BI that the FIG team is particularly tough and the recent departures have added work to those who remained.

The current BoA banker said that after Lukenas' death, there have been meetings about the possibility of reducing hours and more options for working from home.

A former banker at BoA told BI that he quit last year after a period of regularly working 100 hours a week without receiving support for exhaustion or burnout.

They said: 'It got to the point where I woke up and immediately felt like I was going to throw up… My mental health was really bad. I felt very unsupported by my team.”

Bank of America previously said: “Our focus is on doing everything we can to support the family and our team, who are devastated.”

The bank will also pay for all staff attending the late banker's funeral, the bank said.

According to his family, Lukenas served as a Green Beret for 10 years
