Nate Leon's heartbroken family asks whoever killed the hard-working father: Why?

Body reported Sunday by model airplane pilot

GOLDEN, Colo. - Nate Leon's family is heartbroken and hungry for answers.

They want to know why someone killed the devoted family man who delivered Domino's pizza as a second job on weekends because he wanted the best for his wife and three kids, including their twin 4-year-old daughters.

 "They didn't take his phone. They didn't take his car. Twenty bucks and maybe a pizza?  That's worth his life?" asked his mother-in-law, Bernadette Alness. "It wasn't to us."

 "Why? I'd like to know why," she asked. "I want them brought to justice."

Nathan Collin Leon, 27, disappeared on a noon Sunday delivery run from a Denver Domino's. His body was found about six hours later at 151 S. Rooney Rd. in a remote area of Golden by a man flying model airplanes. Police found his delivery car in a nearby location.

Leon died from apparent gunshot wounds, Denver police said. An autopsy to determine the cause and manner of death is pending, the Denver medical examiner said.

"We all have to live now with just memories.  It's all we have of Nate. He was 27 years old. It's not right," Alness told 7NEWS on Monday afternoon.

“He was a loving, hard-working man. He took care of his family and responsibilities,” said his sister-in-law Erin Oswalt, who also was his former manager at Dominos.

"When they ask for daddy. What do you say?  What do you say to a four year old who's wants their daddy?" the sister-in-law asked.

  Leon's wife, Katie Barnhart-Leon, grieved the loss of  the husband she calls "my best friend, my soulmate, the father of my children" on Facebook. The couple has two young daughters.

"Today is ganna be the hardest day of my life... :,(," the wife wrote on Monday morning on Facebook.

In the early morning hours Monday, Katie Barnhart-Leon wrote on Facebook: "Tonight I lay here with a million thoughts running through my head.. I look at my two beautiful little girls as they are having their sweet innocent dreams with no cares in the world.. What are they ganna say in the morning when daddy is not there.. How do you look at your children and explain to them daddy may never come home?? How Do I go on the rest of my life without my best friend, my soulmate, the father of my children, my everything and try to stay strong... I love my husband with all my heart and soul...tonight I ask you lord please please please return my husband home safely if not for me than for our daughters sake.. Please lord..... :,("

Leon's friends said he left the Domino's Pizza at East 40th Avenue and Colorado Boulevard to make a delivery. When he didn't return by 2 p.m, employees called police.

On Sunday afternoon, officers were searching near 50th and Forest. That's where Leon was supposed to deliver the pizza.

The body was discovered in a remote area of Golden by a man flying a radio-controlled airplane. He called 911.

7NEWS has also been told that grief counselors will be at the pizza shop on Monday afternoon to help employees.

 Erin Oswalt has a plea for her brother-in-law's killer:  "Come forth and end this nightmare for my sister and our family."
