Joyeux Stock is unable to forget those last moments she spent with her oldest son Tyler before he left, never to return.
Tyler had spent more than two hours visiting his mother at her job early Tuesday morning before kissing her good-bye.
She thought he was walking to their home on Bruneau Avenue in Kennewick.
"Twenty-five minutes later, he was dead. I'm still waiting to find out why," she said Friday.

Tyler, 20, died from gunshot wounds in the middle of the night on West Buntin Street, only four doors away from her home.
"The last moments with my son were from 10:45 p.m. to 1 a.m. He gave me a hug and kissed me. A few minutes later, I heard sirens, and I knew," she said.
Joyeux recounted a string of activities her son did in the last days of his life, including attending two services at New Hope Baptist Church, where he was a member of the Soldiers of Praise Youth Group.
His visit with his mother had included running an errand to Walgreen's to pick up a movie and something for her headache.
Not an hour later, Tyler was shot dead on the steps of a private residence, killed in what police believe was an attempted burglary.
Police have made two arrests in the case, including the shooter in connection with a drug charge and another suspect who police say joined Stock in the burglary. No charges have been filed related to the homicide.
Tyler's mother said he grew up struggling with everything in life and didn't have a father during the formative years of his youth. He also dealt with racial issues because she is white while his father was black, she said.
But Tyler did have a grandfather who was close to him.
"My dad was Tyler's dad. They did everything together, and even went fishing in Alaska," said Joyeux, recalling their closeness.
She clings to memories of a son who enjoyed being a chaperone at quinceaeras, who played in the church basketball league (because he was always tall for his age) and who was an uncle to his brother's son.
"My son made some bad choices, but he had made some big changes too. He was a good kid, a handsome kid," she said.
Joyeux said the last words exchanged between them were that he planned to walk home.
She assumes it was on that walk back home that Tyler got into a car that ended up being his ride to the house where he was killed.
Although investigators say Tyler had a gun and was attempting to rob a suspected drug dealer when he was shot, Joyeux doesn't believe it.
"I don't know why he did it, but he must have stopped by (my) house for just a short time," she said.
Later that night, she found Tyler's Bible open to the book of Ezekiel with his cell phone placed on the pages.
"To me it was a sign that something wasn't right, and he wanted me to look at it," she said.
"I gave the phone to the police because I want to find some answers," she said.
Joyeux said the amount of concern that has been shown to her is amazing, from people calling or visiting to offer condolences to a special Facebook page -- R.I.P Tyler Stock -- created to record friends' memories of Tyler.
"Every time a new face comes to my door to give condolences, they bring me a new memory," she said.
Tyler was born in Kennewick, attended schools in Richland, then went to Southridge, graduating from New Horizons Alternative High School in Pasco last year.
"I know he wanted to be a better person. He wanted the younger generation of kids to make better choices than he did," his mother said.
Although she doesn't have insurance to cover funeral expenses, Joyeux said she's trying to arrange some kind of a service because so many people have said they cared.
