Friends and family remember the Black Hawk County cousins on fourth anniversary of disappearance

Evansdale held an identification event this evening on the fourth anniversary of Elizabeth Collins and Lyric Cook's disappearance.

On July 13, 2012, police say someone abducted Cook, 10, and Collins, 8, shortly after noon. They were riding their bikes near Myers Lake. Searchers spent the next week looking and even dredged the lake, but weren't able to find either girl.

Then, five months later, hunters found their bodies in a remote area of the Seven Bridges Wildlife Park in Bremer County, but police haven't made any arrest in their deaths.

Law enforcement looked at Wednesday's event as a way to not only remember Cook and Collins but to keep up awareness about child abductions and ways to safeguard against them.

The event took place on Angels Park Memorial Island, set up in remembrance of the girls. There was a station set up where parents could bring their kids and have them complete a quick DNA and fingerprinting kit, as a safety precaution.

Investigators say these kits can make a huge difference in solving an abduction or disappearance case. Elizabeth Collins' father Drew wants parents to understand how quickly it can happen.

"This person is still out there somewhere in our community. We don't know where they are, who they are, but we know they're still out there. They could do this to somebody else, to another child," Drew Collins, Elizabeth Collins' father, said.

People with any information on the disappearance of Lyric Cook and Elizabeth Collins should call Cedar Valley Crime Stoppers at 855-300-8477. There is a $150,000 reward for information leading to an arrest.
