New York medical examiners Sunday ruled the death of Bernard Madoff's elder son a suicide, one day after his body was found hanging in his Manhattan apartment.
Mark Madoff, 46, hanged himself early Saturday with a dog leash in his living room. Madoff took his life on the second anniversary of his father's arrest in the largest Ponzi scheme in U.S. history.
An autopsy Sunday revealed the cause of death.
"It is suicide by hanging," medical examiner's office spokeswoman Ellen Borakove said.
Madoff's father-in-law found his body about 7:30 a.m. Saturday, authorities said. Madoff's 2-year-old son and dog were in the apartment but unharmed. The father-in-law checked on the apartment after Madoff's wife, out of town on vacation, received messages from her husband that caused her to worry, police said.
Madoff and his brother, Andrew, reportedly turned their father in to authorities after he confessed his crime in December 2008. Neither of Madoff's sons has been criminally charged, but prosecutors said they are continuing to investigate the case.
