10News' sister station in Denver, KMGH, obtained the following statement from Walmart regarding the shooting:
The entire Walmart family is deeply saddened by this tragic event. Our thoughts, prayers and condolences go out to the families who lost loved ones and to all who were impacted by what took place. We are assisting law enforcement however we can and are referring all requests for information to them.
Suspect described as unfriendly
Neighbors of the suspected shooter said he was unfriendly and occasionally hostile toward them.
According to the Associated Press, Gerald Burnett said he was sitting on the stairs drinking coffee one morning at his garden-style apartment building in Thornton when Scott Ostrem came down the outdoor stairway. He said Ostrem told him to move and cursed at him.
Teresa Muniz said Ostrem never returned her greetings and once or twice swore at people for sitting in the stairways or leaving laundry in communal machines.
She said she sometimes saw him carrying a bow and set of arrows or a shotgun into or out of his apartment.
Muniz added, most people in the building know one another but she never even knew Ostrem's name until now.
