That article was from April 2018. From looking at discovery lists of evidence so far, it appears they had quite a bit of forensic evidence at the time Prosecutor Junk made that remark. They had ballistics evidence, DNA, shoe print analysis, BPVs, video of the Wags buying supplies at Walmart, hours of interview audio, print and blood evidence from one of the Wagner vehicles. They had nearly a terabyte of data from phone records, voice mails, emails, texts, computers, etc. Over 500 messages relating to custody, also evidence that JW had been bugging the Rhodens, evidence the W's had tampered with the victims phones, etc. AFTER they were killed. LE had already raided the Wags farm on Peterson Rd, Flying W Farms, and the farm on Bethel Hill Rd.
They had a LOT of evidence at that point, so it's kind of surprising to hear Junk say he didn't have any good forensic evidence. In spite of all that evidence, they still hadn't convened a grand jury yet, right?
Maybe Junk was being coy or trying not to show his hand or maybe he was dragging his feet on charging the Wags. Maybe he wanted them to show up at his office to surrender.
