REDDING, Calif. - It was one year ago today that Shane Miller, accused of killing his wife and two daughters, went missing.
It's a case garnering national attention, soon to be the subject of a CNN special.
On Monday, Sergeant Brian Jackson with the Shasta County Sheriff's Office said every day he hopes his office is one step closer to finding him.
"There's not a day that goes by that the topic of Shane Miller doesn't come up," Jackson said.
Miller is on the US Marshal's 15 Most Wanted List.
Miller, 45, is accused of fatally shooting his wife Sandy, 34, and daughters Shelby, 8, and Shasta, 5, at their Shingletown home.
"How or why a human being would do that to another person, let alone children is unfathomable," Jackson said.
After the alleged murder Miller took off, his truck was located in the King Range National Conservation Area on May 8.
"There's not a day that goes by that the topic of Shane Miller doesn't come up," - Shasta County Sheriff Sgt.
Today investigators still believe he remains on the foggy coast.
"That's our last known location that he was for sure," Jackson explained.
Though he admits he could have slipped away, at one point thinking he might've gone out of country or out of state.
Jackson said in a situation like this it's helpful to have the Marshal's Office on the department's side because they can help with the larger search.
Based on Miller's profile detectives still believe he is alive.
He grew up in Humboldt County, familiar with surviving off the land.
Jackson said detectives from the Sheriff's Office try to make it to Humboldt County every three to four weeks.
They were just there last week following up on leads but were unsuccessful.
"It seems like every time we get a lead or a door to open it doesn't pan out and we don't get any further."
In the past year the Sheriff's Office has been flooded with hundreds of leads.
Jackson says they are appreciative of the active public for their attempt to help the department.
Over the next few weeks the department will be re-evaluating evidence and the investigation with the hope of getting more answers.
"As long as he is not accounted for and in custody this office is determined to look for him until that day."
