The Assassination of Abraham Erskine was an assassination on Abraham Erskine by HYDRA sleeper agent Heinz Kruger on orders from Red Skull.
Johann Schmidt had been searching for Abraham Erskine since Erskine was rescued from Schmidt's custody by Peggy Carter and taken to the United States. After locating Erskine in New York City, Schmidt ordered Heinz Kruger to kill him and obtain the Super Soldier Serum.
Erskine was impressed by Steve Rogers, a kid from New York City whom Erskine had interviewed to join the Strategic Scientific Reserve and to train to be a subject in Project Rebirth, the Allied Forces' project to create super soldiers to battle the Nazis.
Erskine liked that Rogers was a good man and was willing to lay down his life for the Allied cause. Rogers had passed all of Erskine's tests at Camp Lehigh and Peggy Carter escorted him to the underground laboratory beneath an antique store, guarded by an undercover agent where the experiment was to be held.
The United States invested money in Project Rebirth, employing its top scientists to the cause, including Howard Stark. Senator Brandt brought journalists and other guests to the secret underground laboratory to witness the project. Kruger, under the alias Fred Clemson, was among the guests.
Project Rebirth was a success. Steve Rogers was now a super soldier. As everyone shook hands and patted backs, Abraham Erskine looked into the observation booth to see Heinz Kruger.
An explosion occurred that surprised all; that was only a distraction as Kruger shot Erskine in the chest and grabbed the last vial of Super Soldier Serum. As Rogers knelt over the dying scientist, Erskine pointed to Rogers' heart, reminding him of the discussion they had the night before. Rogers left to give chase to Kruger.
