CEDAR GROVE, Ind. - Additional skeletal remains were found this week at the site where authorities discovered the bones of 21-year-old Katelyn Markham one year earlier.
Officials with the Franklin County Coroner's Office said an official identification of the remains has not been made, but upon initial observation, "they are believed to belong to Markham."
Markham went missing from her Fairfield, Ohio home in August 2011.
Since then, searchers have combed through a tree-covered creek bed in eastern Indiana trying to find the clues they need to answer the questions surrounding her death.
Indiana State Police received a report from a 911 caller on April 10 that more remains were spotted in the area of Big Cedar Road near Cedar Grove. Markham’s skeletal remains were found at this site in April 2013.
A volunteer search team of about 15 began investigating the site April 19 and discovered solitary human bones later in the day, authorities said.
Digging through layers of mud, rock and discarded items from 8:30 a.m. until after nightfall, the search party was joined by members of Markham’s family.
"Basically we were just going over ground ISP has asked us to go over,” said Dave Rader, head of the Ohio branch of the search and rescue organization Texas Equusearch. "(The officers wanted us) to tidy up a few things, nothing specific. (It was) precautionary to make sure nothing was missed over the past year."
Rader’s team has spent countless hours searching for clues in the case since Markham went missing from her Fairfield home.
Markham’s father, Dave Markham, called Saturday "an emotional day" but thanked the search party for their continued efforts and support.
"They have been my support group for the past nearly three years. Without them, I'm not sure how I would have been able to cope," he said.
Markham's death was ruled a homicide in August 2013, exactly two years from the date of her disappearance. But authorities have yet to name a suspect.
While he wants to move on with his life, David Markham said he can’t until his daughter’s killer is caught.
"There are still a lot of… unanswered questions," he said. "I’m not going away."
A forensic anthropologist in Indianapolis will conduct a post-mortem examination and confirm the identity of the new skeletal remains.
ISP and Fairfield police are working jointly in their investigation into Markham’s death. They ask anyone with information to call ISP at 812-689-5000 or Fairfield police at 513-867-6094.
