Two senior American bankers have been found dead in London over the course of two days in incidents where they both committed suicide. The latest fatal comes from Gabriel Magee, who plunged to his 500-foot death from the 33-store high skyscraper.

Magee had worked for JP Morgan for seven years in London, 10 years in total, and was the vice president in CIB Technology before he was found dead at 8 a.m. on Tuesday morning (Jan. 28). His body was left on the ninth floor roof of Canary Wharf headquarter in London, in full horrifying view of workers in surrounding buildings for up to four hours as police investigated the scene.

"My colleague yelled that he could see that someone had jumped from the top of the building onto a lower roof," one of the traders said. "His body lay there uncovered for at least two hours. Hundreds were looking out of their windows at him. It was bonus week at JP Morgan last week so I hope it wasn't to do with that."

"It's upsetting what's happened but the thought of somebody lying up there for four hours is awful," said another Canary Wharf worker. "I got into the office at about 8:10 and the body was on the floor and there were police up there, and they put a white cover on him. I think he was in a suit. As far as I could see he was dressed appropriately, but there was quite a lot of blood, so me and my colleagues were a bit upset."

The detectives were called to 25 Bank Street at 8:02 a.m., and they are not treating the death as suspicious. "No arrests have been made and the incident is being treated as non-suspicious at this early stage," said Scotland Yard.

Senior colleagues were looking into Magee's recent workload to figure out what may have prompted his death. "They're going to be going through his stuff to try to find out if he'd made some kind of terrible error," his colleague said. "It's possible he had been in the office all night trying to put it right before the fall."

Employees gathered to remember their colleague in a minute's silence in the morning. "We are deeply saddened to have lost a member of the JP Morgan family at 25 Bank Street today," a company spokesman said. "Our thoughts and sympathy are with his family and his friends."

A source close to Magee also said Gabriel Magee was in "good standing with his bosses and colleagues. He was well liked."

The tragic news comes only two days after another shocking death of an American banker. On Sunday afternoon, William Broeksmit, 58, who retired as a senior manager for Deutsche Bank in February of 2013, was found hanging in his South Kensington home.

"He was considered by many of his peers to be among the finest minds in the fields of risk and capital management," said Deutsche Bank Co-Chief Executive Officers Anshu Jain and Juergen Fitschen in a tribute email sent to the employees. "We are deeply saddened by Bill's death. He was a dear friend and colleague to many of us who benefited from his intellect and wisdom."
