Something about Dawn of the Planet of the Apes that has been bugging me since I first saw it.

In the scene where Malcolm and his gang are told to flee the Ape home after Ceasar is shot and Koba burns it down, it has all 5 of them, minus Carver. It was Malcom, his girlfriend and son and the two others who were with them at the gas station. When they are being chased by the apes only Malcolm, his girlfriend and son are shown hiding and the other two have just disappeared. They never show up for the remainder of the movie and it really bugs. Is this just a plot hole of the film or were they killed by the apes? Please help answer it as it is bugging me.
