PUEBLO, Colo. - Longtime person of interest in Keslie Schelling's disappearance, Donthe Lucas, has been arrested for her murder.
"I think it's very, very important that this family has closure," former Pueblo County Sheriff, Dan Corsentino said. "It's been a long time coming."
Corsentino worked as a private investigator for the Schelling family early on in the case and said it was a tough one.
"When you have very little or no physical evidence, and we did not have anyone really talking, the case became very, very difficult," Corsentino said. "There has to be a tipping point that brought this arrest."
Lucas' arrest is the first time since Schelling's disappearance in 2013 that it's being called a homicide.
"It's my professional opinion that Donthe did not act alone," Corsentino said. "I believe that there's others that eventually will be charged."
Corsentino credits the change in leadership at the Pueblo Police Department for the last year of investigative work that's helped get Lucas behind bars.
"I'm hoping very quickly that Donthe will realize that this family has been victimized and he will share information and will close this case out for the family," Corsentino said.
