Sandra Grazzini-Rucki (pictured above right), who has been charged with three felony counts of deprivation of parental rights involving the disappearance of her two daughters, has not surrendered to law enforcement. 

Grazzini-Rucki's attorney, Michelle MacDonald (pictured above left) said on Wednesday evening that she expected Grazzini-Rucki to surrender to law enforcement "by the end of the week."

Reached at her law office on Friday evening, MacDonald declined to comment about the whereabouts of Grazzini-Rucki. MacDonald reversal on commenting came after a meeting at her law office with her criminal defense attorney, Stephen Grigsby. 

Lakeville police consider MacDonald a "person of interest" in the disappearance of the missing girls and have requested to speak with her about any potential involvement. Michael Rhedin, a corrections officer with Hennepin County, is also considered a "person of interest" by Lakeville police in this case. 

Rhedin's son Zachary was recently charged with a felony for property damage at the Lakeville home of the girls' father, David Rucki. 

Grigsby also serves as a criminal defense attorney for both Michael and Zachary Rhedin. 

Samantha and Gianna Rucki both disappeared on April 19, 2013, when they ran away from their home in Lakeville during a custody dispute between their parents. 

David Rucki was awarded custody of all five of his children in November 2013.
