Investigators searching for missing Iowa girls

Investigators are asking for the public's help in the search two missing Iowa girls who were last seen riding their bikes near a lake.

FBI spokeswoman Sandy Breault said Sunday that investigators want to talk to anyone who was at Meyers Lake in Evansdale before 3 p.m. July 13. That's where 10-year-old Lyric Cook-Morrissey and 8-year-old Elizabeth Collins were last seen.

Breault says investigators believe even the smallest details could be crucial in this case, so she encouraged anyone who'd been at the lake to call — even if they didn't see the girls.

Breault declined to comment on details of the investigation Sunday. She says no arrests had been made, but that officials believe the girls remain alive.

Breault says investigators are follwing every lead in the case.
