The search for two missing Iowa girls has moved to a landfill and a closer look into the lake near where the girlsâ?? bicycles were found last week.

Family members of Elizabeth Collins, 8, and Lyric Cook-Morrissey, 10, are pleading for more help in finding the girls. They were last seen Friday leaving Elizabeth's house less than a mile from the lake.

The aunt to both girls, Tammy Brousseau, told The Associated Press she fears the girls were abducted, possibly by a sexual predator.

U.S. Rep. Bruce Braley says the girls' families have asked him to send a letter to FBI Director Robert Mueller seeking assurance that all agency resources were being used.

An FBI dive team using sonar equipment is preparing to search Meyers Lake in Evansdale Friday morning.
