She has also worked with other mothers whose children have been killed, often with an organization started by Valencia’s mother. Hearing the stories of the other mothers, she wondered if she’d ever see her son’s killer brought to justice.

“From all the conversations I had with the other moms, I was discouraged a little bit. Maybe it may happen, maybe not,” she said. “And the sergeant said, 'Well, we know your son didn’t deserve it and (the other man) didn’t deserve it either.' “

Pike Davis most recently checked in with police Tuesday afternoon while prosecutors were reviewing the case. The sergeant had promised to meet Pike Davis if charges were approved.

“When you see somebody, you know they’ve experienced the ultimate loss, and they’ll never get over that,” said Mitchell. “But to be able to provide them with at least some sort of an answer to the multitude of questions I’m sure they have, it is satisfying.”

He and the two other detectives acknowledged how the effort in solving cases like these takes a toll on them because of all the long hours required.

Still, Gillespie said: “You kind of push that to the side. You don’t really think about it. Most of us are lucky we’ve got families that understand.”
 
The trio also credited Detectives Jim Labbe, Jeff Hansson and Dave Healey who worked on the Pike case early on in the investigation. Labbe was recently promoted to sergeant.

On Wednesday afternoon, Pike Davis said she understands that many parents who have also lost a loved one to violence have waited longer than she has for any kind of answers.

The next step, she says, is to find out during Davila’s trial what was going through his head when he decided to take her son’s life.

“No one (could) understand the devastation that comes with losing a child,” she said.
