I know more details but am waiting for them to hit the news. It originally came out as both kids had died ( brother & sister). I received a phone call shortly after saying it was just the brother, they changed the info in the link as well.
Just got a phone call from the woman saying she had to go pick her sister up from school. Her sisters friend is in critical condition and friends brother was killed upon impact.
RIP
