The death of a 28-year-old Jefferies Group investment banker in Dallas, Texas, has prompted a police investigation into the “unexplained death.”

The body of McIntosh, who was assigned to the firm’s team covering technology, media and telecommunications companies, was found in a residential apartment building on Jan. 27, according to records from the Dallas County Medical Examiner’s office. It was not immediately clear whether the apartment was McIntosh’s.

“Based on the date, approximate time and location, this incident is being investigated as an unexplained death,” Dallas police officer Michael Dennis, a public information officer for the department, told Fox News Digital.

His death came just a couple of weeks after Leo Lukenas, 35, who was in the bank’s investment banking group in New York City, died of an acute coronary artery thrombus, according to the New York City Office of the Chief Medical Examiner. 

Lukenas had been working more than 100 hours a week and wanted to leave his job at the time of his death, a recruiter who had talked to him about a new job told Reuters. 

The three deaths have brought into focus the grueling hours that bank workers are known for putting in, but none of their deaths has been officially linked to working long hours.
