(CNN) — Ten people, including a police officer from the town of Boulder, were killed Monday when a gunman attacked a store store King Soopers in Colorado.
Police are just beginning what they say could be at least five days of investigation, and many questions about the shooting and the motivation behind the attack are still unclear. This is what we know so far:
According to Boulder Police Chief Maris Herold, the first calls to 911 reporting shooting occurred around 2:30 p.m. local time (4:30 p.m. ET) Monday, and Officer Eric Talley was the first to get to the place.
At 2:40 p.m., officers radioed that they were in a shootout, according to radio communications.
Nine minutes later, Boulder police tweeted: “Active shooter at King Soopers on Table Mesa. AVOID THE AREA.
Radio communications show that police continued to report that they were being shot with multiple rounds at least 3:21 p.m.
“He is armed with a rifle, our officers fired and returned fire; We don’t know where it is in the store, ”said an agent.
Ambulances and several security agencies responded to the store, which is part of a large shopping center with a two-story store building next to it.
At one point, police officers were seen moving on the roof of the store. The motive for the movements was unclear, but a witness who spoke to CNN affiliate KCNC said that relatives in the store were evacuated through the roof.
Who are the victims?
Talley, 51, died at the scene, Police Chief Herold said. Talley, a father of seven, had joined the Boulder police force in 2010, he said.
Officials did not reveal the identity of any of the other victims, as they had to notify their relatives first.
Who is the suspect?
A suspect is in custody, Herold said, but authorities did not share his identity or any information about the type of weapon used or any possible motive.
As events unfolded, the KMGH helicopter recorded a shirtless man being pulled out of the supermarket. The man had what appeared to be blood on his right arm and leg and his hands appeared to be handcuffed behind him as two officers escorted him. The man was taken by ambulance.
It was unclear if the man was involved in the shooting inside the store.
A senior law enforcement source told CNN that the weapon used in the shooting was an AR-15-style rifle.
What’s next in the investigation?
Police will be on the scene day and night to learn more about what happened at the store, authorities said.
“We will work around the clock to achieve this,” Herold said, adding that such a complex investigation will take at least five days to complete.
The attack comes less than a week after three shootings at massage parlors in Atlanta that killed eight people.
In the United States, so far this year, there have been at least six mass shootings with four or more deaths.
