Below in blue is the timeline from here:

When did Gianni's vehicle get moved by the killer, assuming he was shot someplace in the mall parking lot?
TIMELINE OF KILLINGS
(based on unsealed search warrants and court testimony)
Dec 23:
1900 Gianni purchases two grams of heroin from a drug dealer
2300 Gianni purchases seven Xanax pills from a drug dealer
2318 Surveillance video shows man entering mall, loitering near Ilona's work
2322 Surveillance video shows man on cell phone while loitering
2328 – 2343 Gianni cell phone pinging near Mission Valley mall
2333 – 2343 Gianni cell phone call with uncle
2343 Gianni cell phone call ends with disconnect
Dec. 24:
0012 Ilona and co-worker depart work location
0022 Surveillance video shows Ilona exiting mall with man following her
0114 Ilona calls 911 and says, “I've been shot.”
0124 Police arrive on scene
By the timeline above, 39 minutes after the killer shot Gianni at 2343 he appears on surveillance video again at 0022. So that's 39 minutes to move Gianni's vehicle. (Though, it is still possible the guy on the surveillance video is just a random nobody).
The other opportunity he had to move Gianni's vehicle would be between 0022 and 0114. That's a window of 52 minutes. That would mean he would have followed Ilona out of the mall and then moved Gianni while Sal and Ilona were sitting in the vehicle together during that window.
Recall, the witnesses saw him drive away in a Honda Civic right after the shooting. So I am assuming he had already moved Gianni's car someplace BEFORE the shootings of Sal and Ilona.
Or perhaps....
"In order to carry out the murders of Ilona and Salvatore, abduct and/or kill Gianni, put the body in the trunk of the vehicle and dispose of it over one hundred miles away, it seems reasonable to assume more than one person would be needed to carry out the murders.”
