CARROLL COUNTY, Ind. (WLFI) — Six months have passed since Abby Williams and Libby German were killed near the Monon High Bridge in Delphi.
Half a year later, there are still no arrests.
Police have shared new details in the investigation and reiterate the case has not turned cold.
"We're still very motivated. We're still very optimistic. It's not close to a cold case," said First Sgt. Jerry Holeman with Indiana State Police. "We're just getting dug into this case. We got a long way to go. We have a year's worth of work right now."
Holeman said they are still working hard on the case and they continue to sift through the more than 24,000 tips and leads.
In addition to the thousands of leads, police have served several warrants and have been following up on DNA evidence found at the scene of the crime.
"The question is: Do we have DNA? Yea, we have DNA. We're just still working on determining what kind of DNA. Is it the victims? Is it the known family members or is it our suspect?" said Holeman.
He said detectives test and compare the DNA almost daily, hoping it leads them to the killer.
"We're still working on that," Holeman said. "We can't say, 'Do we have the suspect's DNA or don't we?' We have plenty of DNA, and we have plenty of testing to do, and it takes a lot of time."
ISP released a sketch of the main suspect on July 17. It was put together based on information received during the course of the investigation.
Holeman said they've received more than 3,000 tips from the sketch and it has helped bring in more reliable ones.
"We have plenty of evidence to convict somebody," said Holeman. "Obviously, the person doesn't want to be found."
Police also released an audio recording on Feb. 23. It was found on Libby's phone and features a man saying "down the hill." Police have said there is more audio on the phone, but they have no intention of releasing any more at this point.
Holeman said they are dotting their i's and crossing t's at this time.
"We're still thinking about it daily," he said. "Somebody else asked me earlier how many times have I listened to the recording or how many times have I watched the video. And I said, 'I don't need to watch it anymore because it's embedded in my head.' And you can't let it go."
He said there have been a group of detectives who have been reviewing old evidence, tips and leads to make sure nothing has slipped through the cracks.
Holeman said it's helped lead them to other evidence.
Holeman hopes they will find the person of interest and can begin a court trial within the next six months.
