Stephen Stay, 39, his wife Katie, 34, and their four youngest children were being buried in a private ceremony after services at their Church of Jesus Christ of Latter-day Saints.
"It's a difficult reason that's brought us together today," said Bishop Scott McBride, who presided over the 90-minute funeral service. "It wouldn't be right if I tell you I don't ache in my heart and we don't feel pain and feel the loss."
The couple's 15-year-old daughter, Cassidy, who survived a gunshot wound by playing dead, sat in the front row with grandparents and other relatives, just a few feet from the caskets topped with sprays of flowers. Poster-size photos of her smiling parents and siblings looked back at her and more than 1,000 people attending the service.
Katie Stay's father, Roger Lyon, said in an invocation that the service was a celebration of Stephen and Katie's family and he prayed that "some good come out of this seemingly senseless tragedy."
"We are thankful for all the things they did for us," he said.
In a description of his loved ones' lives, Randy Cousins, an uncle, said the extended family was grateful for support from "friends, family and people we have never met."
"If there's one thing we've learned as a family, it is that the world is a good place," Cousins said. "If you watch the news all the time, you might not remember that."
"Families are forever," Jeff Stay, one of Stephen's brothers, said, his voice halting. "We know we will meet them again."
Cassidy Stay called police and identified her aunt's ex-husband, Ronald Lee Haskell, 33, as the gunman. Haskell had been divorced from Katie Stay's sister and records show he had a history of domestic violence. The family members were shot when they refused to divulge his ex-wife's whereabouts, authorities said. Haskell was arrested a few hours later after a police standoff and now faces multiple charges of capital murder.
"I don't know you ever prepare yourself for something like this because you don't expect this," Don Guthrie, 57, a family friend and fellow church member, said before the funeral. "This is a shock. This is incomprehensible."
"They were the people, despite the chaos of life, who were always looking for happiness and looking to do something better," said Tom Mixon, 47, a father of three and scoutmaster to one of the Stay boys. "Katie Stay was adamant about teaching her kids to do better every day and to treat people better every day. And because of that we all wanted to be better and wanted to be around them. It's hard to wrap my head around it, when somebody that's so ensconced in your life like that is suddenly gone."
Investigators said Haskell tied up the family and put them face-down on the floor before shooting each in the back of the head. Besides Stephen and Katie Stay, also killed were Bryan, 13, Emily, 9, Rebecca, 6, and Zach, 4.
"It doesn't seem right that we have to bury our children first, our grandchildren," said Bradley Foster, one of the Mormon church's senior leaders who came from Utah to participate in the service.
Haskell's lawyers have said they will focus on his mental condition and whether he was legally responsible for the carnage. Prosecutors haven't yet decided whether to seek the death penalty against him.
Friends have said Katie Stay went to Utah last year to help her sister, Melanie, escape her relationship with Haskell. That couple was married in 2002 in California, separated last year and divorced in February.
Stephen Stay was the real estate broker for Moriah Davis, 32, who met the Stay family through their church and had almost daily contact with Katie Stay.
"You cry and talk about how wonderful they were and you move on a little bit at a time," the mother of three boys said.
Davis said her 5-year-old has been talking about 4-year-old Zach Stay and asked her: "Mom, do you think that Zach will like heaven?"
Mixon and Guthrie said their faith had prepared them to forgive Haskell.
"I'm not happy about it, but I'm not going to hold a grudge," said Guthrie.
