EVANSDALE, IOWA - It's a small lake, 26 acres, an oasis of silvery blue in a place where drought and heat are burning the landscape brown.
Residents of this working-class suburb of Waterloo, Iowa, normally picnic at Meyers Lake in the shade of a wooden pavilion next to an old Army tank, or stroll the paved nature trail that circles the lake.
But in the past week, the lake has morphed from an oasis to a specter of mystery, suspicion and dread.
Here, just off the nature trail, authorities found the bikes that two girls were riding July 13 -- the day they vanished. Also on the ground was a purse one of them was carrying when, police now suspect, they were abducted.
"I don't think anybody will be coming here to relax again for a long time," said Brenda Miller, 39, who grew up in Evansdale and on Friday was among residents watching FBI sonar specialists search the lake bottom for Lyric Cook-Morrissey, 10, and her cousin, Elizabeth Collins, 8.
Police said the search, for which they prepared by partially draining the lake, was to rule out the possibility that the cousins drowned.
But they've paid attention to other possibilities too. Last week they interrogated Lyric's father, who has a criminal record and pending drug charges. They also checked the whereabouts of known sex offenders in the region, set up checkpoints to question motorists and offered a $50,000 reward from an anonymous donor.
Authorities and residents in this area of northeast Iowa about 250 miles from the Twin Cities hang onto hope that the cousins simply ran away, as Lyric threatened to do days before the pair went missing, because her dad yelled at her for not doing chores. But with every passing day, it becomes harder for people to have faith that the mystery centered on Meyers Lake will end happily.
