Evansdale, Iowa, police announced they are confident the two bodies found in Iowa Wednesday are the remains of missing Iowa cousins Lyric Cook and Elizabeth Collins.

Lyric and Elizabeth were last seen July 13, when they left their grandmother’s house to go on a bike ride. Their bikes turned up hours later near a lake, but the girls were nowhere to be found.

Now, investigators plead with the public for any clues in the cousins' disappearance as they search for the person or people responsible.
