Jonah Hill's Brother Jordan Feldstein's Cause of Death Released

Jordan Feldstein — who was also Maroon 5's manager — died at age 40 last December

Jordan Feldstein, the brother of actor Jonah Hill and actress Beanie Feldstein, died as a result of a blood clot that originated in his leg, according to online records from the Los Angeles County Coroner’s Office.

The coroner’s office listed Feldstein’s first cause of death as a pulmonary thromboembolism, a pulmonary embolism resulting from a clot originating somewhere else in the body. His second cause of death was deep leg vein thrombosis, a blood clot.

Acute bronchopneumonia and obesity were listed as other significant causes in the death of Feldstein, a music talent manager who died at age 40 on Dec. 22, 2017.

The coroner’s office did not immediately respond to PEOPLE’s request for additional comment.

In January, The Blast reported that the announcement of Feldstein’s cause of death had been deferred pending further investigation.
