The sister of the disgraced late financier Bernie Madoff was found dead from a suspected murder-suicide in Florida, authorities said Sunday.

Sondra Wiener, 87, was found dead in her Boynton Beach home on Thursday afternoon, the Palm Beach County Sheriff’s Office said. She had a gunshot wound.

Authorities declined to fully identify the name of the man found dead with her, citing a request from his family, though his first name — Marvin — and age matches that of her husband. The deceased man was also said to be a resident in the home. Several news outlets reported that he was, in fact, her husband, 90-year-old Marvin Wiener.

The couple’s cause of death remains under investigation by the medical examiner, the sheriff’s office said.
