Family of missing Iowa cousins consults attorney

An aunt of two Iowa girls missing for nearly a week says the family has consulted with an attorney amid growing tensions with law enforcement officers handling the case.

Tammy Brousseau says authorities seem to be treating her family members as suspects — particularly the parents of one of the missing girls, 10-year old Lyric Cook-Morrissey. Brousseau says she thinks police are targeting Misty and Dan Morrissey because they've spent time in prison, mostly due to drug charges.

She says that this week a male family member briefly walked out of an interview with law enforcement in frustration. She didn't identify him.

Lyric and her 8-year-old cousin Elizabeth Collins have been missing six days. On Friday, an FBI dive team plans to search a lake where their bicycles were found.
