Backhoes, shovels and bloodhounds are all part of a refreshed effort to find clues in the disappearance of Kelsie Schelling.
The investigation, now going on four years, brings heartache to two mothers for different reasons
"I have been harassed relentlessly for four years. I have done nothing to anyone," said Sara Lucas, the mother of Donthe Lucas, Schelling's ex-boyfriend.
Lucas, the mother of the only person of interest this case, wants it to be over. But Schelling's mom, Laura Saxton said Donthe Lucas needs to speak up.
"It would just be nice if the person responsible for this would just come forward and tell us where she is," Saxton said, when we spoke with her at the most recent police investigation.
Schelling, who was pregnant, drove from Denver to Pueblo to tell Donthe about the baby in February of 2013. She was last seen in the Walmart parking lot, an unidentified person walking toward her car was caught on surveillance.
Since then, no arrests and not many clues prompted Schelling's family to file a civil lawsuit against the Lucas family and Pueblo police for wrongful death. It was dismissed.
But now there is renewed hope for Schelling's mom.
"I'll always, I think, have hope, but again there's kind of that self-protective thing going on," Saxton said.
Pueblo police said they're able to do these investigations in the Schelling case like the dig in this backyard where Donthe used to live is because of resources that they have.
"We've got some resources lately because we haven't had any major crimes. That's been giving us a time and our detectives time to go out and focus on the case such as this," said Sgt. Eric Gonzales with the Pueblo Police Department.
As Saxton continues to push police to keep her daughter in the spotlight, Lucas' mom is trying to stay out of it.
"Let the wheels of justice take care of their self... I pray for that young lady and i had nothing to do with her disappearance," Sara said.
