EVANSDALE, Iowa — The aunt of two missing Iowa cousins said one of the girls’ mothers has agreed to take a second polygraph test to show she's cooperating with investigators.

Tammy Brousseau said her sister, Misty Cook-Morrissey, was going through the so-called lie-detector test Monday. The test was scheduled to start at 9 a.m. Cook-Morrissey is the mother of 10-year-old Lyric Cook-Morrissey, who vanished with her 8-year-old cousin Elizabeth Collins while the girls were riding bikes July 13.

In addition to the polygraph test, Cook-Morrissey was also scheduled to get a drug screening test. Morrissey said she took a similar screening test last week and passed.

Cook-Morrissey had taken one polygraph test last week, but said she would not take another after complaining she was harshly interrogated and accused of having something to do with the disappearance.

Brousseau says that position caused friction within the family and investigators to complain of a lack of cooperation. She says Morrissey agreed to the second test on the condition that she could have a family member present.

Cook-Morrissey's estranged husband, Dan Morrissey, took a polygraph test two days ago, according to the missing girls' aunt.

Brousseau said investigators have not informed them of any new developments related to the search. She said she’s not sure if that means if there are no new developments or if investigators are holding something back.

Over the weekend, authorities put out a renewed call for anyone who had seen the girls on Friday, July 13, to contact investigators.
