Some of the people at the Colorado King Soopers were actually there to get the COVID vaccine

• A witness said his family walked into the pharmacy of the King Soopers grocery store to get the COVID vaccine just before the shooting.
• The man said the suspected shooter "shot the woman in front of [his family]."
• The family hid in a coat closet for an hour, trying to stay quiet.

Some customers at the Boulder, Colorado, King Soopers supermarket were there to get their COVID vaccines when an active shooting incident happened, ending in the deaths of ten people, including a police officer.

"I got a call that my daughter, grandchildren, and son-in-law walked into the pharmacy to get a COVID vaccine," a witness told CBS News.

According to the supermarket's website, King Soopers rolled out its vaccine program across Colorado starting February, with dozens of supermarket-linked pharmacies offering doses of the Moderna COVID vaccine to eligible people. The store also offers anti-body testing.

King Soopers is part of the Kroger grocery store company. There are nine stores in the Rocky Mountain region.

The Boulder Police Department tweeted about an "active shooter" at the Table Mesa King Soopers grocery store at around 2:49 p.m.

Police and the FBI then swarmed the scene.

The witness told CBS that he was in contact with his daughter, who said that the suspected shooter had "shot the woman in front of them."

The family ran and hid in a coat closet, staying quiet to avoid attracting the notice of the shooter. They were saved an hour later by cops who showed up to rescue them.

"This is not okay with me," the man said, adding that he was putting in a big pitch for gun control.

"When it's your family, you feel it."
