A 90-year-old former Morgan Stanley advisor who allegedly shot his co-worker in their office last month has died, according to published reports.

An obituary in The Oklahoman said Leonard Bernstein died on July 28. It noted that he suffered from mental illness.

Early last month, Bernstein was arrested and charged with shooting his co-worker, Christopher Shawn Bayouth, 61, multiple times in his torso, back, leg and foot, police said. He was charged with shooting with intent to kill and released on a $50,000 bond. 

Morgan Stanley fired Bernstein a day after the incident and sought a temporary restraining order against him.

Bernstein was charged with shooting Bayouth at a Morgan Stanley office in which they worked in Oklahoma City. Witnesses reported that Bernstein calmly left the office and took off in his vehicle after shooting his co-worker multiple times. Police said Bayouth identified Bernstein as the shooter when they arrived at the scene. Berrnstein was later apprehended during a traffic stop and taken into custody, police said.

Bernstein began his career with Morgan Stanley in 1994, according to BrokerCheck. He joined Citigroup Global Markets in 2004 and left in 2007 to rejoin Morgan Stanley, where he stayed for five years before moving to Wells Fargo. In September 2021, he returned to Morgan Stanley.

The obituary noted that Bernstein was born in New York City and was a U.S. Navy veteran. “At the end of Leonard’s long and exemplary life, he unfortunately struggled with mental health issues,” the obituary said.

The obituary noted that Bernstein was a successful businessman in the stereo speaker industry before switching careers to become a broker in the 1990s.

The obituary described him as a man with "charisma, a quick wit, a great sense of humor [and] extreme intelligence" who was "an avid reader of the classics and Greek history."

It said that he was married to his first wife, Esther, for over 25 years and together they had three children. In 1983, he married his second wife, Dianne, who had two children that he accepted as his own, the obituary said. “Dianne and Leonard enjoyed almost 40 years of happiness together until his recent death,” the obituary said.
