In looking at home invasions and abductions, it's not as uncommon as you would think. In one recent case, the child was the target and the connection was that the perp had seen the mother and child in a grocery store (Thomas Evans, SC abducted a 4 year old girl in Feb 2018). In another case, the homeowners had a for sale sign on their front lawn and that drew in the perp. DC and JC may have stopped for gas on the way home, been followed by someone who took a liking to JC and he waited until midnight to grab her.
