No. I just looked it up. The car with Shirley's luggage tag was found in the John Norman Collins area of Ann Arbor on M-14, months AFTER Joe Scolaro died. Shirley's luggage tag was found in the Ann Arbor/Ypsilanti area near where the bodies of the dead co-eds were found.Sort of but not really. I think the car with the luggage tag was found near ROMEO, MI, which is 72 miles from the main Collins stalking grounds in Ann Arbor. Romeo is only 34 miles from Lathrup Village, MI, and 50 miles from the New Hudson Airport. Romeo is in Macomb County, which is mostly suburbs and rual areas north of Detroit. It is just a few miles east of Oakland County.
(Forget about Romeo, Romeo is totally inconsequential. It is irrelevant that the police officer just happened to punch his time cards at the Romeo police station).
According to Mardi Link's book, page 110, the luggage tag was in a blue Chevy with Ohio license tags, sitting on the side of the road on M-14.
According to Wikipedia, M-14 runs through the area of where the 6 victims of John Norman Collins were found.
"M-14 is a 22.54-mile (36.27 km) east–west state trunkline highway in the southeastern portion of the US state of Michigan. Entirely freeway, it connects Ann Arbor with Detroit by way of connecting with I-96."
The John Norman Collins Michigan Murders were a series of highly publicized killings in the Ann Arbor/Ypsilanti area of Southeastern Michigan between 1967 and 1969 that terrified Washtenaw County for over two years.
