Police have not had any luck making an arrest.
Police have issued a new composite sketch of a person believed to be connected to the slayings of two Delphi teenagers earlier this year.
Police circulated this photo of a man who was on the Delphi Historic Trails on February 13.
Libby German and Abby Williams were reported missing by their family on February 13.
In the five months since that day, Indiana State Police, the Federal Bureau of Investigation and multiple other agencies across the state have spent countless hours investigating and interviewing witnesses and possible suspects.
"The suspect is described as a white male between 5'6" to 5'10", weighing 180 to 220 pounds and with reddish brown hair.
German was able to capture a photo of a man and his voice on her cell phone before she died. The words "down the hill" are heard. Police said the girls' bodies were about three-quarters of a mile from an abandoned railroad bridge where they were dropped off a day before to go hiking. Police say it's very important for the public to focus on the facial features. Additionally, this sketch depicts a hat that may not be accurate.
According to Riley, authorities have been working on the composite drawing for "a while" throughout the five-month investigation with help from people who have come forward in the case.
A reward in excess of $230,000 is being offered for information leading to the arrest and conviction of the person responsible for the double homicide.
