Liberty German loved to go hiking, and safety was a regular topic of discussion in her home. "It was something that I stressed, but I guess not enough," says Liberty's grandfather, who raised the teen along with his wife. Like many in the small Indiana community of Delphi, Mike Patty says he "can't imagine" why someone would've wanted to kill his 13-year-old granddaughter and her best friend, 14-year-old Abigail Williams, both of whom were found dead near the popular hiking spot of Monon High Bridge at the Delphi Historic Trails on Tuesday. "I just don't know—my mind is really mush right now," he tells People.
Police, who have not named a suspect or cause of death, said Wednesday they hoped to find a man photographed at the trails around the time the girls were there on Monday. With the exception of that man, "we've talked to everybody that we feel that has been through there and none of them are coming up as suspect," Indiana State Police Sgt. Kim Riley said Thursday, per the Concord Register. Later Thursday, Riley told the Lafayette Journal & Courier that officers had interviewed a man and searched his home not far from the trails in Delphi but no arrests were made. It wasn't immediately clear if the man was the same one photographed Monday. (Read more murder stories.)
