In February 2019, the Investigation Discovery channel aired a two-part, four-hour documentary about the killings. At this same time, WXYZ-TV investigative reporter Heather Catallo announced that a key suspect, convicted child sex offender Arch Edward Sloan, had failed a polygraph test when he was interviewed by the Oakland County Child Killer Task Force in 2010 and 2012. Back in 2012 new DNA technology found that Sloan's car contained hair with the same mitochondrial profile as evidence found on the victims; however, it is not Sloan's.
