fact they had not. Instead of seeing the actual massacre, what each instead saw was the other murdering Wally. From there, Wally stole Booster's time-traveling tech, went five days into the future, killed his future self and brought his future body back to present day to leave at the scene. Wally's machinations are what led Booster to discover that dead Wally's body was five days too old. Wally then relocated all the bodies of the others he had slain, staging the murders to place himself above suspicion, and set up Harley and Booster as the prime suspects instead. To complete the subterfuge, Wally then destroyed Sanctuary's computer and robot attendants, and scribbled the now-infamous "The puddlers are all dead" on Sanctuary's living room wall. He successfully misdirected everyone involved in the investigation until Ted Kord, Booster Gold, Batgirl and Harley Quinn figured out that Wally was the key to the murders, and they devised a way to track Wally's time disturbance by utilizing Skeets and Kord Industries tech. They show up just as Wally is about to kill five-days-older-Wally, and five-days Wally reveals that after he accidentally killed everyone in Sanctuary, he didn't travel back in time to “unmake” his mistake because that's what Barry did during Flashpoint, instead he sent the confession files to Lois Lane to try to “make up for what happened,” telling the world what he'd done at Sanctuary, and encouraging people to get help before they made the same mistakes he did. Five-days-older Wally reveals that this is the same thing that happened to him five days ago - that he also didn't kill the older Wally. Booster Gold explains that they can still “close” the loop, even without the dead body of five-days-older Wally. They can go to the 25th Century and “speed-clone” older Wally. Then younger Wally can take that cloned body back to the past. The Justice League eventually arrived and arrested Wally for the murders. In The Flash #761, it was revealed that Eobard Thawne was responsible for manipulating Wally into killing the heroes at Sanctuary. Later this whole story was recollected in The Flash Annual #1 (2021), stating that Wally West was not responsible for these deaths, and it was revealed that Speed Force itself had actually caused it when trying to expel Savitar from its corridors.
