Mackenzie Shirilla faced criticism from her late boyfriend Dominic Russo’s sister after a new prison selfie surfaced while she serves time for the deaths of Russo and their friend, Davion Flanagan. Two days after the photo was posted, Russo’s sister, Christine Russo, told TMZ that she did not approve of Shirilla, 21, sharing a photo from behind bars. #christinerusso #mackenzieshirilla #dominicrusso #davionflanaga #crime
