Iowa cousins Elizabeth Collins and Lyric Cook-Morrissey missing

Authorities are draining an Iowa lake as they continue their search for two missing girls whose bicycles were found nearby.

Eight-year-old Elizabeth Collins and her 10-year-old cousin Lyric Cook-Morrissey were last reported seen Friday afternoon leaving their grandmother's house. Their bicycles and Elizabeth's purse were found later that day near a bike trail at the edge of Meyers Lake in the northeast Iowa city of Evansdale.

Black Hawk County Chief Deputy Rick Abben says the draining of the nearly 5-acre lake began Monday and it could take up to three days. Officials believe it will go faster due to the low level of the lake and the Cedar River into which it drains.

The lake has already been dredged, and hundreds of volunteers swept the area over the weekend.
