DELPHI, Ind. – Hours before the families of Libby German and Abby Williams hold a drop-in candlelight memorial to mark the second anniversary of the Delphi eighth-graders’ deaths, Carroll County, state and federal law enforcement officials give an update on an investigation still looking for a suspect who killed the girls while they were on a Delphi trail on Feb. 13, 2017.

Carroll County Prosecutor Nicholas McLeland called for a 1:30 p.m. Wednesday media session to recount what happened that day and refresh what’s known in the case.

Mike Patty, Libby’s grandfather, said he hasn’t heard from law enforcement whether to expect new bits of information or clues about a suspect. Investigators who descended by the dozens on Delphi, about 17 miles northeast of Lafayette, after the homicides have not provided new information to the public in more than 18 months.

“I’m not sure what they can share right now,” Patty said. “But anything that keeps the case out there and maybe gets someone to think about making a call about whatever they might know, that’s going to help. Anything that pushes us closer to getting this guy.”

Abby, 13, and Libby, 14, were found near Deer Creek by a search party on Feb. 14, 2017, a day after they were dropped off the day before to walk the Monon High Bridge Trail, a popular spot on Delphi’s trail system.

Police have been tight-lipped about the case since releasing a sketch of a possible subject, grainy photos captured by Libby’s phone of a man walking on the abandoned rail trestle and an audio file of a man saying, “Down the hill,” which also came from Libby’s phone.

Since then, police on the case say they’ve interviewed more than 1,000 people and fielded more than 30,000 tips.

MEMORIAL PLANNED: From 5-7 p.m. Wednesday, the Delphi United Methodist Church, 1796 U.S. 421, will host an evening of prayer and remembrance for Abby and Libby. The evening is a chance for people to come and go, rather than a formal service. The families of Abby and Libby encourage people to bring non-perishable food and pet food to the church that evening. For those who can't make it to Delphi, the families say they're encouraging people to donate in Abby and Libby's names to a food pantry or animal shelter in their hometowns.

ABOUT THE SUSPECT

Police continue to look for a white male between 5-foot-6 and 5-foot-10, weighing 180 to 200 pounds, with reddish brown hair. The description was taken from images on Libby German’s cellphone of a man walking across Monon High Bridge that day – wearing blue jeans, a blue jacket and a hat – and from composite done by an FBI sketch artist, based on information from a witness who saw a man fitting that description.
