Boy in stolen car killed by owner who tracked down vehicle with app in Denver

Police in Colorado said Thursday they were investigating a car theft and the fatal shooting of a 12-year-old boy found inside by the car's owner after an exchange of gunfire.

No arrests have been made in Sunday's shooting in Denver, and it is still not known who stole the vehicle, police said. They spoke at the scene with the man who owns the car.

The car's owner used an app to track his vehicle, found it stopped in an area about 12 miles away and, when he approached it, there was an "exchange of gunfire" with at least one person inside the car, police said in an initial update on the shooting. It was not clear how many people were in the car.
