UPDATE: State Police to interview sex offender with possible connection to Delphi murders

Indiana State Police investigators have arrived in Colorado to interview Daniel Nations, an Indiana man who may be connected to the Delphi murders, according to our sister station

Nations has been arrested in Colorado on charges of felony menacing and reckless endangerment.

The Carroll County sheriff confirmed they're looking to see if an Indianapolis man, arrested in Colorado, is connected to the Delphi murders of Liberty German and Abigail Williams.

Police in El Paso County, Colorado, said 32-year-old Daniel Nations, a registered sex offender in Indiana, was arrested Monday afternoon.

Police said he was driving a red Chevrolet Prizm with expired Indiana license plates.

His vehicle was suspected in several menacing complaints in the Colorado Springs area, including threatening mountain bikers with a hatchet.

Nations was booked into jail on a charge of weapons possession by a previous offender.

It happened in the same area where a mountain biker was murdered last weekend.

Police said the current charge is not related to the murder and would not say if they believe those crimes are related.

On Wednesday evening, Carroll County Sheriff Tobe Leazenby said Nations is being considered when it comes to the Delphi investigation.

"Remain vigilant, because at this stage, obviously, we don't know whether or not this is the individual we've been looking for," Leazenby said Thursday. "I would still encourage folks to -- whatever their spirituality or faith may be -- to pray, cross your fingers, whatever the case may be and hope that this may be it."

As you may remember, the bodies of 14-year-old Liberty German (Libby) and 13-year-old Abigail Williams (Abby) were found in the woods near Delphi in February.

The girls' families said they're cautiously optimistic.

"It's not a sigh of relief yet. The sigh of relief will come when we get the phone call, 'We got him,'" said Becky Patty, Liberty German's grandmother.

"Until we get that call, we need to stay vigilant on this guy," said Mike Patty, Liberty German's grandfather. "Keep spreading the information around, keep spreading his picture, the brochures you see out there. Share it with your friends, share it with everybody else. Let's stay on top of this and continue to call those leads in, no matter how small they may seem. We need them all. I want to make this guy's world as small as possible until he's caught."

"I feel like every time this happens, it's kind of like Christmas Eve," explained Anna Williams, Abigail Williams' mother. "It's like, you know it's coming. You know it's coming. You feel it's coming, and then you're just waiting for that okay to open the present, and that will be a large gift to our family."

Nations is being held on a $10,000 bond.
