A 25-year-old private-equity associate died in midtown Manhattan on Monday. His father said that the cause of death was suicide.

• A young man who worked in private equity was found dead outside an apartment complex in New York City on Monday.
• The man, 25-year-old Drew Miller, died by suicide, his father said.
• Miller worked in financial services. He had been employed by GreyLion Capital since April.

Drew Miller, a 25-year-old private-equity associate from Warren, New Jersey, was found dead outside of a high-rise apartment complex in New York City on Monday. The cause of death was suicide, his father, Andrew Miller, told Insider by phone on Wednesday.

“Suicide is not a rational act. We’re all devastated,” Andrew Miller said, speaking on behalf of his family.

Miller fell from the high-rise building Windsor Court, which is located on Lexington Avenue between East 31st and 32nd Streets. His body was found by police after they responded to 911 calls shortly after about 8 a.m. Monday morning.  

Emergency-medical-services personnel pronounced Miller dead at the scene, according to Annette Shelton, a spokesperson for the New York Police Department. Shelton confirmed Miller’s identity in an email to Insider on Tuesday afternoon, and added that an investigation was underway.

Since April, Miller had been working as an associate at GreyLion Capital, a New York firm focused on growth-stage investments. GreyLion was spun out from the asset-management arm of Perella Weinberg Partners last year.

“Drew was an incredibly bright and talented individual who was well liked and highly regarded by all who had the pleasure of working with him,” Jody Shechtman, a partner and the head of marketing and business development at GreyLion, wrote in an emailed statement to Insider on Tuesday afternoon.

“We are incredibly saddened by his passing. Our deepest sympathies are with Drew’s family and loved ones during this difficult time,” Shechtman added.

Andrew Miller added that senior executives from GreyLion had been in touch with the Miller family to express their condolences.

AM New York, a local publication, reported the death of an unnamed man on Monday but did not identify him in its article. 

Miller’s body was found with several personal effects, AMNY reported. Among them were a backpack and duffel bag, a laptop computer, a tablet, medication, and house keys, the outlet said.

Before joining GreyLion, Miller was an investment-banking analyst at Cain Brothers, an independent healthcare-focused investment bank that was acquired by KeyBanc in 2017. 

Cain Brothers CEO Robert Fraiman and Chief Administrative Officer Danielle LeBenger did not immediately return Insider’s request for comment on Tuesday afternoon.

Miller worked at Cain Brothers from 2018 to 2021. He attended Indiana University’s Kelley School of Business from 2014 to 2018 and obtained a bachelor’s degree in finance, according to his LinkedIn page.

Suicide is complex, and the reasons behind a suicide are not always immediately clear. Risk factors include mental illness or a history of trauma, and many people considering suicide exhibit warning signs. Treatment is available to help people overcome suicidal thoughts and better cope.
