The term "smiley face" became connected to the alleged murders when it was made public that the police had discovered

Gannon and Duarte have theorized that the young men were all murdered, either by an individual or by an organized group of killers.
The term "smiley face" became connected to the alleged murders when it was made public that Gannon and Duarte had discovered
graffiti depicting a
smiley face near locations where they think the killer had dumped the bodies in at least a dozen of the cases.
Reception of the theory
Other police forces that have investigated the deaths dispute the conclusion that the cases are linked. Police departments that are involved do not currently view the deaths associated with smiley faces present at the scenes as serial-killer activity.

police department, which was in charge of eight of the investigations, concluded that the deaths were accidental drownings of

calls the serial-killer theory "ludicrous," arguing that the evidence does not fit what is known about serial killers.

Rosario noted that Kristi Piehl, the original reporter on the theory, and some of the parents of the deceased have since expressed skepticism despite initially supporting the idea. Another parent, Kathy Geib, is working with Piehl and others, but their main goal is to convince police to take a second look at cases of alcohol-related drownings.
