Pennsylvania State Police and forensic experts are digging deeper into a grim discovery found on a Ross Township, Monroe County property last week.
Investigators are trying to identify the human remains and determine how they got there.
State Police entered the property, owned by Michael Horvath, under a sealed search warrant.
Investigators spent nine days on his property related to the 2013 disappearance of Holly Grim. Grim vanished from her Lower Macungie home in 2013. Grim and Horvath worked together at Allen Organ. Horvath has not been charged.
It's not yet clear what probable cause detectives had to get approval for the warrant because it's under seal.
Dr. Dennis Dirkmaat, a forensic anthropologist at Mercyhurst University, said he was contacted by troopers about the remains last week.
According to Dirkmaat, investigators sent him pictures via text message, wanting to know if the skeletal remains were in fact human.
He said after he told police they were human, troopers requested Dirkmaat and his team of ten graduate students on site.
"Not to just collect the remains, but to try and figure out what happened at the scene and reconstruct past events," Dirkmaat said.
Dirkmaat says his team helped find additional remains. He said they're still working on an inventory of what was found.
Though investigators confirmed they visited the property as part of the Holly Grim investigation, it's not yet clear if the remains belong to Grim.
Monroe County's coroner said it will take several weeks for DNA results to come back.
In the meantime. Dirkmaat said team is working on analysis that may help investigators piece together what happened.
"We have a pretty good idea, of the back story as to how they got there, how they were distributed. Then the process is analyzing the skeletal remains themselves," Dirkmaat said.
That analysis may answer crucial questions.
"Age, sex, stature and things like that, then the process would be looking at the bones carefully to determine any evidence of trauma, a knife wound, bullet wound or anything like that," Dirkmaat said.
Dirkmaat said they'll also be looking into how long the remains were there, where it was originally, and who moved it.
