The Latest on the investigation into the 2017 killings of two northern Indiana girls (all times local):

3:40 p.m.

Indiana State Police have released a statement clarifying information about a newly-released sketch of a man suspected of killing two teenage girls in 2017.

The statement Wednesday said that the sketch police released Monday of a youthful-appearing man "more accurately represents the person" they believe killed 14-year-old Liberty German and 13-year-old Abigail Williams in February 2017.

Their statement says a composite sketch released in July 2017 of a middle-aged man was developed early in their investigation but the man it depicts "is not presently a person of interest in this investigation."

Police add that the new sketch is "representative of the face of the person captured" in video taken from German's cellphone of a man walking on an abandoned railroad bridge.

A newly released sketch of a man suspected of killing two Indiana teenagers in 2017 was created only days after the girls' slayings, but authorities aren't saying why they held onto it for more than two years.

Indiana State Police initially released a composite sketch five months after the February 2017 killings of 14-year-old Liberty German and 13-year-old Abigail Williams depicting a white man with a goatee.

The sketch released Monday shows a clean-shaven, younger-looking man with significantly different facial features.

A state police sketch artist tells The Indianapolis Star he drew it three days after the girls' bodies were found.

Police spokesman Sgt. Kim Riley declined to answer any questions Wednesday about the sketch.

Police Superintendent Doug Carter said Monday that "new information and intelligence" leads police to believe it depicts the killer.
