Nearly a year after the abduction of two eastern Iowa cousins, authorities investigating their deaths say most details surrounding the case remain confidential.
The Black Hawk County Sheriff's Office says officials continue to aggressively investigate the slayings of Elizabeth Collins and Lyric Cook, but they have no additional details to release at this time. They called the case very complex.
Captain Rick Abben said in a statement released Thursday that much of what is known in the case must remain confidential in order to preserve the integrity of the case.
Elizabeth was 8 and Lyric was 10 when they were last seen in July 2012 riding their bikes near Meyers Lake in Evansdale. Their bodies were later found in a wooded area in December.
