The official cause of death for 43-year-old Jessica Aber, a former U.S. attorney appointed by Joe Biden, has been disclosed. Aber, who was found deceased in her home in March, died from “sudden unexpected death in epilepsy” while sleeping. The Alexandria Police Department initially stated there was no evidence suggesting her death resulted from anything other than natural causes.

Aber’s family confirmed she had battled epilepsy and epileptic seizures for years. During the Biden administration, she served as the U.S. Attorney for the Eastern District of Virginia before resigning when President Trump returned to power in 2017. She gained national attention for prosecuting high-profile cases, including a CIA leaker and Russian war criminals.

One of her notable prosecutions involved Asif Rahman, a former CIA analyst who pleaded guilty to leaking classified documents about an Israeli military plan targeting Iran. Aber also oversaw the extradition of a defendant linked to fraudulent visa schemes involving Israeli citizens. She emphasized the severity of such actions, calling them a “violation of his oath” and stressing their impact on national security.

In 2019, Aber was honored with the Department of Justice’s Assistant Attorney General’s Award for Exceptional Service.
