“Why?” Thats the question that keeps the fiancé of Alan Waller up at night. Waller who is also a father was gunned down in his driveway on a Sunday morning over a lawn care dispute. Waller wanted to talk to the neighbors landscapers about ongoing issues with them leaving their debris in his driveway. Home surveillance video shows the female neighbor walking to mentor Wallace doorstep while he takes them to the side of the house to show them the debris. The home doesn’t have cameras on the side of the house but within seconds of being out of frame things go wrong (see video)
