— Tali'Shepard's thoughts while revisiting the site of the attack.

The Jacobus Assassination Attempt, also known as the Jacobus Assassination Plot and Presidium Commons Terrorist Attack, was an attempt on the lives of Tali'Zorah and Keenah'Butras by Jacobus Sassus at the Presidium Commons on the Presidium, Citadel that occurred during the Eden Prime War. Marking the last of two attempts to silence Tali and Keenah, the other on Illium, the attack took place after Tali and Keenah were turned away by C-Sec authorities, and Jacobus tried assassinating them on the Presidium Commons. He instead accidentally killed a C-Sec officer and injuring Tali and Keenah, forcing him to chase them. The engagement ended with Keenah sacrificing his life to kill Jacobus in an incinerator, allowing Tali to escape and ending the threat Jacobus posed.
