2011 nissan murano not moving
 

My sister has a 2011 nissan murano that won't start or move. This car was daily driven up until last Saturday on december 5th. We don't think its the battery seeing how all the lights and stereo still function normal. However the car won't turn over without being boosted off, and when it does start and goes into gear it doesn't move. I will be looking at it again this Sunday so I'm open to all ideas or suggestions
