Probably of no relation to this case, but just out of my own curious fancy, I looked up missing persons in Iowa. From late 2016 to early 2018, three girls went missing in the stretch between Black Hawk County (near Waterloo) and Cedar Rapids. All three were listed as white with brown hair and eyes, 16 years old, 5'1", and between 130-140lbs.
There was another one last August from Marshalltown, white with brown hair and eyes, was 19, 5'4", and 170lbs.
I can't find any more specific information about them, but at least the first three are unnerving in their similarities to each other.
Also these are the same areas of the summer of 2017's rural road sexual assaults.
