I believe the picture of the car released today is the one in the same as the one mentioned in that article.
Silver Nissan 2010-2012, Silver or light colored.
ETA: Nissan Altima is NOT a suspect vehicle. Only seen at nearby business before murder. Contact tipline 972-775-7624.
Looking at the Nissan in the vehicle... at bottom on the passenger side there are around 3 areas that are lighter than the surrounding area. They could be some kind of scratches or marks. But then again, they might just be reflections of light that are bouncing off that water on the ground behind the car. Anyone care to guess which it is?
