(CNN)-- An Iowa family that's been hoping for good news since two young cousins disappeared in July now has to prepare for the worst.
Hunters discovered two bodies in a wooded area Wednesday afternoon, Black Hawk County sheriff's Capt. Rick Abben said.
He said the family of Lyric Cook, 10, and her cousin Elizabeth Collins, 8, has been notified, although the bodies have not yet been positively identified. The bodies were being taken to the state medical examiner's office in Ankeny, Iowa.
"Right now, it's looking like the outcome was not the one that we wanted," Abben said at a news conference in Evansdale, Iowa.
The girls were last seen by their grandmother on July 13 when they left for a bike ride. The girls' bicycles and a purse were found near Meyers Lake hours after they were reported missing.
A search of the 25-acre lake in July turned up nothing, and authorities said they believed the cousins were abducted.
"Cooperation with law enforcement is the key factor in discovering the whereabouts of Lyric and Elizabeth," FBI spokeswoman Sandy Breault said in July. "Unfortunately, in this case, law enforcement has not received total cooperation from all family and close friends," she said.
Abben said the investigation is ongoing, and he thanked the public and the media for their assistance and support in the case.
