Iowa cousins missing: Hunters find bodies of Lyric Cook-Morrissey and Elizabeth Collins

Black Hawk County sheriff's Capt Rick Abben said during a news conference that the bodies were found on Wednesday afteoon in a wooded area, but he would not give a specific location.

Abben says both are being sent to the state medical examiner's office to verify they are the bodies of 11-year-old Lyric Cook and 9-year-old Elizabeth Collins.

The two girls vanished July 13 near Meyers Lake in Evansdale, about 110 miles northeast of Des Moines.

Their bikes were found near the lake, as well as a purse -  hours after they were reported missing in Evansdale, a northeast Iowa town of about 4,700.

Abben appeared to be fighting back tears as he said, 'the outcome was not the one we wanted.'

Abben says the area where the bodies were found is still being processed.

'This is a difficult thing for us to go through. It's a difficult thing for the community,' he added, recalling how officers had worked around the clock looking for the girls.

The girls' families have asked the media to respect their privacy, and they offered no immediate comment.

Grandmother: Wylma Cook, pictured, was believed to be the last person o see the girls before they vanished

The girls were last seen leaving from their grandmother's house on their bikes.

The grandmother, Wylma Cook, has said Lyric knew not to go far because the girls planned to leave for the home they shared in nearby Waterloo with Lyric's mother, Misty Morrissey, by 1:30pm.

She said that she expected the girls to retu for lunch or a drink of water or juice as they always did when they were playing in the heat.

'That's what's just so strange about all of it,' she said.

Mrs Cook said she got nervous when they weren't back by 12:30pm and started driving around town looking for them.

After an hour of searching, she retued to the home. Mrs Cook said that Misty Cook-Morrissey stopped by after getting off work.

'Misty said, "Mom, you go home and I'll just wait for Lyric and bring her home," Cook recalled.

Mrs Cook said she drove to her home but was soon told by Elizabeth's father the girls hadn't surfaced. A firefighter found the bikes two hours later, and the manhunt began.

Estranged: Lyric's parents, Misty and Dan Morrissey, both have checkered criminal pasts - and were investigated as persons of interest in the disappearance of the girls

Hundreds of volunteers canvassed the area in the following days, traipsing through cofields and wooded areas. The mayor even flew above in his private plane looking for them.

Abben said additional details would be released at a news briefing on Thursday.

Lyric's father Dan Morrissey was investigated as a person of interest shortly after the girls disappeared because of his ties to the local methamphetamine trade.

But authorities have said he is not considered a suspect is the girls' disappearance.

After examining the fleeting footage of the girls racing through a coer of the screen, police concluded that they must have been kidnapped.
