According to law enforcement sources, Callella was detained after investigators uncovered

new evidence that allegedly linked him to key moments in the

timeline surrounding Guthrie’s disappearance.

Officials have not disclosed the full nature of that evidence but confirmed it includes

digital records and witness statements that were not available

during the early stages of the search. Authorities emphasized

that the arrest does not conclude the case, but rather marks

a critical turning point in understanding what may have happened.

In a briefing, investigators outlined what they described as the suspected motive,

explaining that it centers on a personal dispute that escalated in

the days leading up to Guthrie’s disappearance.

While details remain limited,

authorities said the motive was established through

corroborated testimony and documented communications.

They declined to comment on whether additional

individuals may be involved, citing the sensitivity of the ongoing proceedings.
