đź“ş Official solution video

“Hey, sonny, I got something interesting from James, the girl’s father.”

“Interesting? What’s that, Chief?”

“He says, he just found Maria’s iPad.”

“Chief… I just got an idea! I will call you back.”

Well-well-well... an iPad… Will it allow me to access her iCloud? I have to check one useful article…
