UPDATE: A steady stream of investigators continue to come and go from the Seven Bridges Wildlife Area in Bremer County, where two bodies were discovered by hunters on Wednesday.
Just before 2 p.m. Thursday, multiple vehicles with Nebraska license plates arrived at the park. One larger truck had a trailer with an ATV. A state trooper blocking public access to the park confirmed the group to be a team of FBI investigators.
At least 15 other vehicles have entered the park since noon. Earlier in the day, a group of investigators walked along 270th Street, the only access road to the area, and marked the area with yellow flags.
A sheriff says hunters discovered the bodies, believed to be two missing cousins, in the secluded wildlife area about 25 miles from where they vanished in July.
Bremer County Sheriff Dewey Hildebrandt said Thursday the bodies were found in the area, along the Wapsipinicon River, that is popular for hunting and fishing.
Hildebrandt says investigators from his office, the FBI, Iowa Division of Criminal Investigation and other agencies are processing the crime scene.
Authorities said hunters Wednesday discovered bodies believed to be Elizabeth Collins and Lyric Cook. Elizabeth was 8 and Lyric was 10 when they vanished while bike riding in Evansdale on July 13.
The bodies have been sent to the state medical examiner's office in Ankeny for identification. Authorities will release more information Thursday.
