A New Jersey man who killed three people over a Facebook post has been sentenced to 375 years in prison. Jeremy Arrington, 32, was convicted last month of murdering 23-year-old Syasia McBurroughs, 11-year-old Al-Jahon Whitehurst, and his little sister 7-year-old Ariel Little Whitehurst, because he was angry over something the siblings’ mother had shared on social media.
