Evansdale police say an autopsy has confirmed that two bodies found last week in a wildlife area are those of Elizabeth Collins and Lyric Cook.
Police Chief Kent Smock says he received confirmation Monday from the Iowa State Medical Examiner's Office that the bodies were the two cousins, who had been missing since July 13. The full autopsy hasn't been released to police.
Elizabeth was 8 and Lyric was 10 when they went for a bike ride in the northeastern Iowa community and didn't return.
Hunters found their bodies last week in the Seven Bridges Wildlife Area in Bremer County, about 25 miles from where they were last seen.
Authorities closed the park while they searched for evidence connected to the case but now have reopened the area.
