Initial reports say a member of the Afghan security forces is responsible for the attack, NATO's Resolute Support mission said in a statement. And they offered heavy praise to Taylor for his service, both in the military and in civic matters.
In less than a day, a GoFundMe set up to help Taylor's family had raised more than US$135,000.
It said the incident was being investigated and the wounded service member was in a stable condition, but did not release the identity of the service member who had been killed. Taylor, 39, leaves behind a wife and seven children, aged 13 years old to 11 months.
Herbert noted that Taylor, who deployed to Afghanistan in January and had planned to resume mayoral duties in North Ogden once the stint ended early next year, has five brothers who also serve in the Utah National Guard. He said others had discouraged Taylor from deploying a fourth time, telling him, "You've done enough".
He anticipated that his deployment would last 12 months and reassured North Ogden citizens that the city would be left in good hands.More news: Lacazette: Arsenal believe we can can compete against Premier League elite
Additional information will be released as appropriate, officials said.
Friends described Taylor as a passionate and outgoing mayor who was continually looking for new ways to serve his country and his state.
"What we do for our country is very unsafe business, but it's important to remember why we do it", Burton said. North Ogen's population is 19,465, according to 2017 U.S. Census estimates.
There was no immediate claim of responsibility for the "green-on-blue" attack - in which Afghan forces turn their weapons on global soldiers with whom they are working.More news: Trump Announces Planned Crackdown on Asylum Seekers
"Believe me, they're hurt by this as well", said Burton.
Taylor became the city's mayor in 2013.
Also on hand at Sunday's press conference were Phillip Swanson, a member of the North Ogden City Council, North Ogden City Attorney Jon Call and Toby Mileski of Pleasant View.
U.S. Sen. Orrin Hatch, R-Utah, in a Twitter message, described Taylor's death as "devastating" news.
The Utah National Guard has not publicly confirmed or discussed the circumstances of Taylor's death, which was confirmed to CNN by a government official.More news: Pentagon sending 5200 troops to secure border as mid-term elections loom
