What neighbors heard before Virginia mother, 3 kids were killed

Police urged neighbors, who are still in the process of coming to grips with the tragedy, to check their door or surveillance cameras to see if there is anything suspicious. John Shisler, who lives one block down away from where the shooting happened, said he told officers he heard something unusual shortly before 5 a.m. "Just thought I heard a car rolling down the road a little faster than normal for that time of night and this neighborhood," Shisler said.
