DELPHI, Ind. (AP) — Police say a task force investigating the slayings of two northern Indiana teenage girls didn’t find any solid evidence during the search of a house.

No one has been arrested in the deaths of 14-year-old Liberty German and 13-year-old Abigail Williams. Their bodies were found Tuesday, a day after they went missing from a hiking trail near Delphi, about 60 miles northwest of Indianapolis.

Indiana State Police Sgt. Kim Riley says investigators could request more search warrants such as the one that was served at a home outside Delphi Thursday evening.

Police have released a photo of a man on the trail whom they want to question.

Visitation for the girls is set for 4-8 p.m. Saturday at the Delphi High School gymnasium, with private funeral services scheduled for Sunday.
