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, Aber led the Office of the U.S. Attorney for the Eastern District of Virginia before resigning after President Trump’s 2017 inauguration. She gained national recognition for prosecuting high-profile cases, including a CIA leaker and Russian war criminals. One notable case involved Asif Rahman, a former CIA analyst who pleaded guilty to leaking sensitive documents about an Israeli plan to strike Iran. Aber also oversaw the extradition of a defendant from Israel accused of facilitating the illegal entry of Israeli citizens into the U.S. through fraudulent visas. She criticized Rahman’s actions as violating his oath and endangering lives, while highlighting the impact on U.S. foreign relations and intelligence operations. In 2019, Aber received the Department of Justice’s Assistant Attorney General’s Award for Exceptional Service.
