Zaevion Dobson, 15, was shot and killed in the Lonsdale area late Thursday as he shielded young friends from gunfire. Brandon Perry was shot and killed hours later and crashed his car at the Green Hills Apartments complex.

According to KPD, the men being sought may have "information that could help in identifying the suspects."

Anyone who knows their whereabouts is asked to call KPD's crime information line at 865-215-7212.

Dobson's funeral is set for Saturday, Dec. 26, at Overcoming Believers Church in East Knoxville. Friends will be received from 11:00 a.m. until 12:30 p.m. with services to immediately follow. Dobson will be buried at the New Gray Cemetery in Knoxville.

Dobson was a sophomore at Fulton High School. He was a football player, a kid brother, and a son. He's now hailed as a hero for his brave instincts to protect others by putting himself in harm's way.

"Zae was a kid who always had a smile on his face, a fun-loving kid," said Rob Speas, principal of Fulton High School. "Zae and his brother Zach are both great young men and their mother is incredible. She is really involved with the school and does so much. His reaction just shows what kind of children she has raised."

An autopsy showed Dobson died from a single gunshot wound, according to KPD.

An autopsy showed Perry was shot multiple times.

Police are not releasing the caliber of weapons involved in the shootings because the information is part of the investigation.

The sign in front of Fulton High School acknowledges the death of 15-year-old Zaevion Dobson.

President Obama commented on Dobson's death on Twitter, calling Zaevion "a hero at 15."

"It is kind of surreal, to think this incident in our home neighborhood in the Lonsdale community has made an impact all the way to the White House," said Speas. "The piece that we can learn from Zae is to think of others first rather than think of ourselves."

Monday afternoon, the lights on the marquee in front of Fulton High School read "ZAE #24" in honor of Dobson. The 24 refers to his number on the football team.

The numbers that show how far his story of sacrifice has reached are staggering.

A fundraising site to help the Dobson family with arrangements raised almost $60,000 in two days. People from New York City, New Orleans, Nebraska, Iowa, and Canada were among those commenting about how this story touched them.

Fulton sophomore Zaevion Dobson, #24, plays against Knoxville Catholic High School in the 2015 4A football playoffs.

"I received several emails from people across the country who said, 'Hey, I'd like to donate to a scholarship if something like that is created.' So we decided that would be a good way to honor Zae and make sure he is remembered for years to come," said Speas. "The Fulton High School Alumni Association created the Zaevion Dobson Scholarship Fund and we've raised almost $4,000 so far."

While the family of Zaevion Dobson prepares to bury the 15-year-old the day after Christmas, Speas and others want to ensure his memory lives on for years to come.

"You really don't make a decision in those moments. You just react. And the way Zaevion reacted was to take care of other people. A kid made a split-second decision to take care of others," said Speas.
