Federal investigators used a "stingray" device to track Michael Cohen, as they tried to pin down exactly where he was staying at the Loew's Regency Hotel in New York City, according to newly unsealed documents. Nearby cell phones connect to the stingray device, thinking it is a cell phone tower. Federal agents used the device, which they called a "triggerfish" in the documents, to track Cohen’s location in April 2018. They figured out which hotel room he was staying at based on the pings from his phone, according to the court filings. One day later, the FBI raided Cohen’s hotel room, and other properties.
