A new reward fund has been established to help police arrest the killer of two eastern Iowa cousins whose bodies were found early this month.

A fund drive has raised $20,500 and is available when someone is arrested in the killings of Elizabeth Collins and Lyric Cook. Typically such funds are not paid out until there’s a conviction.

Black Hawk County Sheriff Capt. Rick Abben says in a statement released Friday that officials believe someone has helpful information.

A separate $150,000 reward is offered through law enforcement officials and a private donor for information leading to an arrest and conviction.

Elizabeth was 8 and Lyric was 10 when they went bike riding July 13 in Evansdale and didn’t return.

Hunters found their bodies Dec. 5 in a wildlife area.
