MANISTEE -- Since the discovery of the human jaw bone at the marina construction site last week in Manistee, police and other crews have continued to search the area for additional bones.
Friday crews used a ground penetrating radar operation. The results were reviewed Wednesday morning and the investigators found seven anomalies in the data that warrant additional investigation and excavation.
Two of the spots are of high interest and the rest of lesser size and suspicion. The Manistee Police Department will begin with the excavation of the first two and them move to the other five.
All spots are going to be examined.
The suspicious spots can be anything from buried metal, rock and debris to human remains. The data simply paints a three dimension portrait of difference in the strata at 1 foot intervals. The suspicious spots are mostly at 7 feet deep and are horizontal to the surface.
The two most suspicious spots are pretty much side by side and very close to the hole that was dug near the sidewalk. It is from this hole that police believe the original bone fragments came from.
Police are meeting with investigators, contractors and tribal representatives to determine the next steps.
Over the weekend, Michigan search and rescue personnel were on site with cadaver dogs to work the area. Officials say the dogs indicated a couple of spots that warranted additional investigation.
Tuesday Officer and members of the Tribal Historic Preservation department were on site to sift through the area. The sifters found five small bone fragments, two were animal and three are probably human. These bones were turned over to the medical examiner who will send them to the anthropologist for examination.
Like the other bones, these appear to be very old and weathered.
The anthropologist who will be looking at the bones is out of the country for at least two weeks. It is currently unknown when this person will get a look at the bones or how long it will take to get information back to investigators.
