A Man Has Been Charged With 10 Counts of First-Degree Murder in the Colorado Grocery Store Massacre

The man suspected of gunning down 10 people at a Colorado supermarket-bought a high-powered weapon less than a week before the massacre, officials said Tuesday.
The suspect, whom police identified as Ahmad Al Aliwi Alissa, 21, was charged with 10 counts of first-degree murder in connection with Monday’s mass shooting at the King Soopers grocery store, Boulder Police Chief Maris Herold said at a news conference.
Alissa bought a Ruger AR-556 on March 16, according to an arrest warrant affidavit, citing law enforcement databases.
The court document did not explicitly identify the weapon used in Monday’s shooting. Witnesses described the killer as using an AR-style weapon, the affidavit said.
