Boulder King Soopers shooting: Cellist pays tribute to 10 victims at memorial outside grocery store

A cellist paid tribute to victims of a mass shooting this week in Colorado by playing outside of the King Soopers grocery store Tuesday.

In a video uploaded to Instagram, an unknown cellist plays across the street from King Soopers as mourners gathered to place flowers at the foot of the fence surrounding the store’s parking lot.

Hundreds of people paid their respects at the growing makeshift memorial near the supermarket, adorning it with wreaths, candles, banners reading "#Boulderstrong" and 10 crosses with blue hearts and the victims’ names.

Who were the victims of the Boulder King Soopers shooting?

Several community vigils were planned to honor the victims who died on March 22. The Boulder Police Department invited the public to show support for Officer Eric Talley, who was killed, by witnessing a police procession Wednesday as his body was taken from the coroner’s office to a funeral home in the Denver suburb of Aurora.

Talley had been with Boulder police since 2010. He was the first to arrive after responding to a call about shots fired and someone carrying a rifle, officials said.

"He was by all accounts one of the outstanding officers of the Boulder Police Department, and his life was cut too short," Boulder County District Attorney Michael Dougherty said during a press conference.

Boulder Police Chief Maris Herold late Monday said Talley had "served in numerous roles supporting the Boulder Police Department and the community of Boulder." Friends described Talley as a family man, FOX 31 Denver reported.

The other victims 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.

Leiker, Olds and Stong worked at the supermarket, a former co-worker said.

Mahoney’s daughter, Erika, called her father a "hero" and said he represented "all things love."

"I'm so thankful he could walk me down the aisle last summer," she wrote on Twitter with an image of the two on her wedding day. "I love you forever Dad. You are always with me."
