Cocaine, long popular among New York professionals, is now often tainted with fentanyl, catching users unprepared and driving drug fatalities
NEW YORK—Ross Mtangi, a trading executive at Credit Suisse Group AG, left his Manhattan penthouse in March 2021 with his laptop and told his pregnant partner he was going to work.
He checked into a nearby hotel and tuned in to work calls. Later, he texted for cocaine from a drug delivery service. A man wearing a baseball cap, cross-body bag and face mask appeared on hotel surveillance.
