BOULDER—The suspect jailed on 10 counts of murder in this week’s mass shooting in Colorado has been moved to another detention center because of “safety concerns and threats,” and he faces additional attempted-murder charges, officials said on Friday.
Boulder County District Attorney Michael Dougherty and Boulder Police Chief Maris Herold told reporters they were still trying to learn what drove Ahmad Al Aliwi Alissa to open fire on Monday at the King Soopers supermarket in Boulder, some 28 miles (45 km) northwest of Denver.
