Following the implementation of Order 66, a security control point was established at that location. It was staffed by members of the Grand Army of the Republic and Coruscant Security Force given its positioning on a frequently used path leading away from the Jedi Temple.
During an attempt to traverse the checkpoint, three Padawans were discovered, which resulted in a melee as they made efforts to flee. Jedi Knight Etain Tur-Mukan, who was also in the process of crossing the bridge to meet with Clan Skirata for an evacuation, died when she intervened to protect a clone trooper from a descending lightsaber's strike. Her spouse, Darman Skirata, Kal Skirata, along with multiple members of Clan Skirata, all observed her demise, but were unable to recover her remains amidst the resulting pandemonium, thus entrusting the responsibility to Jaller Obrim.
Niner and Darman also could not be saved. Niner sustained significant injuries after a Jedi Padawan, who was trying to escape, attacked him and caused him to fall from the bridge onto a maintenance parapet. Although Darman was heartbroken by the loss of Etain, he found himself unable to abandon his squad leader and brother, opting to remain with him instead of evacuating off-world with the remainder of Clan Skirata.
