iPhones are both popular with thieves and help catch them. AppleInsider has a nice roundup of Apple crime-related stories. They include how $19m worth of iPhones were stolen, and how one device helped bring in a Mueller investigation witness.
A fraud ring based in New York stole $19 million worth of iPhones over a period of seven years. Per Quartz, the perpetrators ran a scam in which they posed as cell phone subscribers, received new iPhones at little to no cost by using fake IDs and fraudulent debit cards, and then sold the phones on the black market. The case was reported earlier this spring, but the full criminal complaint was unsealed this week, revealing the perpetrators operated the scam in at least 34 states.
