DELPHI, Ind. — It has been more than five years since Abby and Libby went to the Monon High Bridge, never to return home. Here is what we know so far about the case.

An investigation began on February 13, 2017 when family members reported them missing. The search resumed in the morning, and their bodies were found around noon on February 14.

The case sparked national media attention and endless speculation as the killer remains on the loose years later.

A new lead developed with police appealing for tips about the “anthony_shots” social media profile. Police traced that profile to an individual named Kegan Kline, who was being investigated in connection with a child exploitation case. He has never been charged or named as a suspect in connection with Delphi murders.

In recent months, Indiana State troopers have been searching the Wabash River in Peru potentially looking for evidence tied to the case.

Authorities will hold a news conference on Monday with additional details, law enforcement sources tell CBS4.

Below is an interactive timeline of everything we know so far about the Delphi case.
