That ATM transaction was to locate Garcia and Rivera on their Tallahassee-to-Miami itinerary. Remember, this is a circumstantial case. There is no direct witness to the shooting. All we have is a neighbor who witnessed the green Prius fleeing the crime scene. So they have to place these two Miami residents in Tallahassee and demonstrate how they got there. If you read the PC carefully, they don't even say exactly where the ATM transaction took place: it's somewhere between Tallahassee and North Miami but closer to Miami since 7 hours had passed since the shooting. These cell phone tower data, toll records, rental car receipts, surveillance videos from adjacent premises and buses, and even the ATM transaction are used to place these two in Tallahassee or on their way or returning from Tallahassee. It is intended to show that these Miami residents, who had no business being in Tallahassee, were there to commit the crime.
The ATM transaction probably had nothing to do with the crime. Kathy Magbanua would have to be an idiot to wire a large sum of money to Rivera's bank account right after the killing. More than likely they were paid in cash: Charlie to Kathy, Kathy to Garcia, and Garcia to Rivera. People do contract killings for as little as $10,000 cash. This was an out-of-town killing which involved 2 contractors, 2 separate trips, staying 2 nights at 2 different motels, casing the joint, and following Markel around for 2 days to minimize collateral damage to ensure that the kids are not present when Markel's killed. I'd be surprised if they did this for less than $25,000. Probably more like $30,000 - $80,000. But remember, money is not exactly an issue for the contractee(s) here. The Adelsons own 3 Mercedes, 2 Lexus and a Ferrari, which Wendi and Charlie used to drive. They were probably paid above the going rate and told to take extra care to leave the kids untouched and not leave their fingerprints anywhere:
