12:23 PM PT —Christine Russo joined us today on “TMZ Live” Wednesday, where she explained that Mackenzie‘s behavior is making a mockery out of their family’s tragedy.
Mackenzie Shirilla is posting glammed-up prison selfies on Instagram … but Dominic Russo‘s sister tells TMZ all she sees is a convicted killer soaking up attention online.
Mackenzie’s new prison selfie and a message saying she’s “trying to do better every day and holding on to hope” has Christine Russodemanding prison officials investigate whether she’s improperly accessing social media behind bars.
Christine tells TMZ … “As Dominic Russo’s sister, it is heartbreaking to see someone convicted in connection with my brother’s death appear to have a social media presence while our family is suffering every day. While my brother is buried, seeing her post selfies, full face of makeup, and bragging how she is famous is painful and, to me, completely inconsistent with remorse.”
Dominic’s sister goes on to encourage anyone with similar concerns to contact the Ohio State Reformatory for Women and “respectfully ask the warden to investigate” whether any prison rules regarding electronic devices or social media are being violated…
