Cause of Death Reportedly Revealed for Missing US Attorney Found Dead Inside Federal Building After Being Reported Missing

The cause of death of a federal prosecutor who once served twice as acting US Attorney based in San Diego has reportedly been revealed.

As previously reported, a caller informed the San Diego Police late Wednesday evening to report that Haden might be missing.

A short time later, he was discovered dead by law enforcement in an office at 880 Front St. in Downtown San Diego.

Southern District U.S. Atty. Adam Gordon confirmed b Haden’s death in a statement, calling it “one of the darkest days in our office’s history.”

“But there was nothing dark about Andrew Haden’s life,” he added.

Now, the New York Post exclusively reports that Haden died by hanging in an apparent suicide.

This should not come as a surprise since San Diego Police Department spokesperson Ashley Nicholas previously noted that no foul play was suspected.

Per the Post, an investigation into the incident remains ongoing, and the San Diego medical examiner will determine the official cause of death.

As The LA Times notes, Haden had worked for the U.S. attorney’s office since 2010 and twice served as acting U.S. attorney for the Southern District of California during transitions of leadership.

The first was around two months in 2023, and then another two-month stint in 2025.

Haden also served in the US Navy for five years and completed two deployments in Iraq and Liberia.

After serving America, Haden attended law school at the University of San Diego and served as a court clerk for US District Judge Thomas J. Whelan in the Southern District of California.

Haden leaves behind a wife and two children.

Family members remembered him with several comments shared on social media.

“Shocking, heartbreaking, surreal, just can’t wrap my head around it at the moment. Always remember TOMORROW NEEDS YOU! 988 RIP LT Andrew Haden,” one family member wrote on Facebook.
