McGuire credits media coverage and hundreds of thousands of online shares of photos Kuijer's face and the getaway van for his arrest there.

"It's because of those efforts that Kuijer is in custody today. And the community is safer today than it was before his arrest yesterday."

McGuire says Nathan's mother Whitney Dumas and the woman stabbed at RBC were "elated" to  learn of Kuijer's arrest and are overwhelmed by community support and well wishes.

A funeral for Nathan is planned for Friday afternoon. Dumas says she has been informed the cost of Nathan's funeral will be covered by police's victims' services office.

A GoFundMe page initially set up to help pay for the boy's funeral had raised close to $24,000 by Wednesday afternoon.

McGuire, a former homicide detective says his family has a long road ahead.

"My experience in the cases that I've been involved in is these things just don't get better. They may get better incrementally, but it's just a huge, unthinkable void in everyone's life to have to deal with something like that."
