DELPHI – The newest bit of evidence released Monday by the task force investigating the murders of two Delphi girls is a new sketch of the killer.

The sketch appears to be younger than the original sketch of the suspect released two years ago.

Indiana State Police Superintendent Doug Carter also asked the public for information about an abandoned vehicle. It as parked at the old DCS-PSC welfare building in Delphi and was abandoned on the east side of 300 North of the Hoosier Heartland highway.

They also released a two-second video of the suspect taken from one of the girls’ phone which shows the man walking on the Monon High Bridge.

"This video has never before been publicly released. The video shows the suspect walking on the bridge. When you see the video, watch the person's mannerisms as they walk. Watch the mannerisms as he walks. Do you recognize the mannerisms as being someone you might know?"

Superintendent Carter had a direct message for the killer.

"Directly to the killer, who may be in this room. We believe you are hiding in plain sight. For more than two years you never thought we would shift gears to a different investigative strategy. But we have. We likely have interviewed you, or someone close to you. We know that this is about power to you and you want to know what we know. And one day, you will."

"What will those closest to you think of when they find out that you brutally murdered two little girls? Only a coward would do such a thing."

Also released Monday was an additional bit of audio which sounds like the killer saying “guys” and then the original clip of him saying “down the hill”.
