An Uber spokeswoman issued a statement saying: "We are heartbroken by the loss of one of our partners, Grant Nelson. Our deepest sympathies and prayers are with his family and loved ones during this incredibly difficult time."



Police said the suspect "declined to make a statement" after being taken into custody.



The terms and conditions posted on the ride-sharing giant's website say that customers must be at least 18 to use the service. The spokeswoman was not immediately available to say how that is enforced.



A service for Nelson, who attended New Trier High School, is planned for noon Friday at Chicago Jewish Funerals in Skokie.
