According to two sources at Harvey Apartments- where Wednesday night’s suicide occurred- the suspect Harold Smith kept to himself and was involved in dubious behavior.

"Harold probably got caught up in something or someone snitched on him,” a neighbor, who requested to remain anonymous, told RadarOnline.com. The neighbor added that while he thought Harold was “a cool cat,” he sold drugs, including weed.
