DES MOINES, Iowa - Authorities investigating the disappearance of two Iowa cousins missing for nearly a week say it is a distraction that one set of parents have consulted an attorney and may not be cooperating 100 percent.

Family members say Misty and Dan Morrissey, parents of 10-year-old Lyric Cook-Morrissey, have talked to an attorney who is advising they stop talking and taking polygraph tests.

Black Hawk County Chief Deputy Rick Abben says that's a distraction and authorities expect 100 percent cooperation.

He says investigators have been aware of the Morrisseys' criminal record since Friday when Lyric and her cousin, 8-year old Elizabeth Collins, didn't return from riding bicycles in Evansdale in northeast Iowa.

Both Morriseys have spent time in prison on drug charges. Abben says background checks were done all family members and they have taken polygraphs.
