From the linked article in question:
Indiana State Police (ISP) said earlier they have no information to "specifically include or exclude" Nations as the suspect in the killings of Abby and Libby. The state police announced the lack of conclusive findings to date in a news release Oct. 3, following the conclusion of a visit to Colorado by two ISP detectives.
Prior to that visit, 11 News spoke with the sheriff in the county Delphi is located, who said his office was not labeling Nations, and everyone is considered a person of interest.
Among the things investigators are working to figure out is where Nations was at the time of the Delphi murders on Feb. 13 and if he was even in Indiana. The police say they've received thousands of tips in connection with the killings, and many of the tips have included pictures.
Nations remains in jail. <italicized by my to highlight quote>
To me, “investigators are working” <BBM> reads as if this is happening now, at the time of publication (10.27 with an update on 11.2), not what happened prior to ISP traveling to CO.
JMO.
I read it as meaning prior to the Indiana State Police going to Colorado to investigate. We know he was in Indiana as he signed in for his SO registration.
i guess we'll have to wait and see how this turns out.
