I obtained the Michigan State Police file on the Robison family murders, which happened on 6/25/68 in Blisswood, Emmett County, Michigan, near the town of Good Hart.
It is a rather large police file. It is 59.1 MB, 437 pages. It is in the form of a PDF. Thanks to Doranchak, it is now accessible to anyone who wants to do research. It is available here:
https://drive.google.com/file/d/1-plREV ... puKiP/viewIt is of interest to me and some other researchers of the Zodiac case because like the Zodiac at LHR 12/20/68 (and the killer at SB 6/4/63), the shooter used Winchester .22 Super X ammo, fired from a gun six grooves and lands with a right twist, with police reports identifying a (Sears) J.C. Higgins as the weapon most consistent with the rifling pattern on the bullets and the weapon most likely to have been used.
It is also of interest because someone with inside knowledge of the crime scene wrote to the local paper, asking his name to be put in the paper if police wanted more info, and his name was ZODIUS. The words ZODIUS and ZODIAC share the first four letters in common, both derive from the Latin word ZODIACUS and both mean essentially the same thing, a collection of the twelve animals/symbols representing astrological signs. Zodius struck on 6/25/68, six months before Zodiac, and one year before Zodiac announced himself to the world.
Both Zodius and Zodiac used math symbols - Zodius used triangles, Zodiac the unit circle, a circle with a plus sign over it. Both had messages with the letters R,O,E,B,E,R,T in them, and both emphasized the letter sequence EBE.
Like Zodiac, Zodius wrote to a newspaper, giving crime scene knowledge only the killer could know, demanded his cryptic message and name appear in the paper and targeted a male - female couple - Zodiac teens and young adults on dates, Zodius a husband and wife with kids present. Like the killer at possible Zodiac crime of Santa Barbara 6/4/63, Zodius posed his victims by stacking bodies atop one another and exposing the female. Former FBI agent and serial killer profiler John Douglas cites a study which shows less than 1% of all homicides involve posing of bodies.
Like Domingos and Edwards were covered by a blanket, Mrs. Robison was covered by a blanket. Zodiac shot through a window (car), and Zodius shot through a window (house).
Zodius called from San Francisco, and people who heard his voice described it as robotic & monotone, similar to how the voice of Zodiac was described.
There are other similarities, and also differences...
And aside from the possible Zodiac connection, it is a tragic case, and deserves to be solved. You can learn more about it starting on Page 1 of this thread. I think that the only major named Zodiac suspect with ties to both the Midwest in general and Michigan specifically is Ted Kaczynski. You can read about evidence linking him to the Robison murders and other Midwest murders here:

To start, here is the evidence about the ballistics in the Robison family murders by Zodius matching Zodiac:
Michigan State Police ballistics report on Zodius Robison family murders of 6/25/68, noting weapon was .22 with six lands and grooves, right twist, notably consistent with a (Sears) J.C. Higgins pistol.


Ballistics report on Zodiac Jensen/Faraday murder of 12/20/68 at Lake Herman Road, noting weapon was a .22 with six lands and grooves, right twist, most consistent with a (Sears) J.C. Higgins pistol.
Ammo used in both cases was Winchester .22 Super X.
