Case Background in Polk County
Lyric Cook-Morrissey, age 10, and her cousin Elizabeth Collins, age 8, disappeared on July 13, 2012. The cousins set out for a summer bike ride and never returned.
Their bikes and a purse were later found near Meyers Lake. Although the kidnapping happened in Evansdale, law enforcement agencies across Iowa, including those in Polk County, joined the search and investigation.
