Citing NYPD sources, FOX Business Network’s Charles Gasparino reported police are looking into whether Lee’s suspected suicide was potentially "related to some business-related issue." Sources said no note was left, Gasparino also reported.

"The family is extremely saddened by Tom’s death," Michael Sitrick, a family friend and spokesperson, said Thursday in a news release. "While the world knew him as one of the pioneers in the private equity business and a successful businessman, we knew him as a devoted husband, father, grandfather, sibling, friend and philanthropist who always put others’ needs before his own. Our hearts are broken."

Lee was known for leveraged buyout transactions, among other things. He notably conducted a $1.7 billion sale of beverage company Snapple in 1994, two years after purchasing it.
