Coloradans have created makeshift memorials after a mass shooting killed 10 people at a grocery store in Boulder on Monday.

People placed flowers, messages and other mementos atop a police car at the Boulder Police Department on Tuesday in remembrance of fallen Officer Eric Talley, 51, who was first to arrive at the scene of the shooting and was killed in the line of duty.

"Thank you #Boulder," the Boulder Police Department tweeted Tuesday with a photo of the memorial. "Your kindness means more than we can say right now."

Homer Talley, 74, described his son as a devoted father who "knew the Lord." He had seven children, ages 7 to 20.

"We know where he is," his father told The Associated Press from his ranch in central Texas. "He loved his family more than anything. He wasn’t afraid of dying. He was afraid of putting them through it."

The other dead ranged in age from 20 to 65. They were identified as Denny Stong, 20; Neven Stanisic, 23; Rikki Olds, 25; Tralona Bartkowiak, 49; Suzanne Fountain, 59; Teri Leiker, 51; Kevin Mahoney, 61; Lynn Murray, 62; and Jodi Waters, 65.
