On Monday afternoon, a gunman killed 10 people, including a police officer, in a store in the city of Boulder, in the U.S. state of Colorado, which had witnessed the two worst massacres in American history.

Witnesses said they first heard gunshots inside the “King Supers” store in Boulder, which is home to about 110,000 people and is located 30 miles northwest of Denver, the capital of west-central Colorado.

According to U.S. media reports, the shooter fired an AR-15 machine gun, a very common weapon in the United States that has been used by a large portion of mass murderers in the country.

Colorado State Attorney Michael Dougherty said Tuesday that the “Boulder” attack bomber was named, 21-year-old Ahmed Al-Alaiwi Al-Issa.

The district attorney said Ahmed is a resident of Arvada, Cor Colorado, who has lived most of his life in the United States.

Ahmed is facing 10 counts of first-degree murder, according to Maris Herolide, the city’s police chief, according to a CNN report.

The incident follows an attack last week in which a gunman killed eight people at Asian massage parlors in Atlanta, Ga.

There is a great deal we do not know about the killer, his motivation, and other critical aspects about this shooting, but know this: as president, I will use all the resources at my disposal to keep the American people safe.
