Credit: Mackenzieshirilla/InstagramConvicted double murderer Mackenzie Shirilla has launched yet another appeal in an attempt to overturn her convictions. The 22-year-old has challenged almost every part of the case against her in a new petition seen by TMZ. Interest in the case has surged since Netflix released a documentary titled The Crash earlier this year about Shirilla and her crime. Mr Bradley claimed Shirilla’s trial attorneys failed to present evidence that her boyfriend, Mr Russo, grabbed the steering wheel. “What hurts even more is seeing how modern social media culture allows violent offenders to gain attention, followers, donations, publicity, and influence from the crimes that destroyed families like mine,” she said.
