Was Spanish Fork teen intentionally killed or was it an accident?
Cannon said his office didn't know why certain people were refusing to cooperate. He said some have had dealings with police before, possibly explaining why they are a little less friendly to deputies. Others, detectives believe, are afraid of implicating themselves by admitting they were at a party where alcohol was being served.
But while underage drinking is taken seriously by the sheriff's office, in this case it takes a back seat to a dead teen.
"We take action against that under normal circumstances. These are not normal circumstances," Cannon said. "I don't care if you drank a six-pack. If you know what happened here, tell us."
While some party guests were being quiet to police, several have been vocal on Facebook about the incident, purporting to know exactly what happened.
Preston Haun has been monitoring some of that activity.
“There's still so much chatter. We're getting all kinds of stuff on there," he said. "Rumors, speculation, you know. Truths, half-truths, I don't know."
The Utah County Sheriff's Office has also been monitoring the comments being posted on social media. Cannon cautioned that posting too many unconfirmed rumors could hurt the investigation.
"We don't want somebody saying something that will discourage people from talking to us or that will give people an idea of what happened that is really not accurate," Cannon said. "There's a lot of red herring posts that we've seen, people claiming to know exactly what happened."
At least one person police looked at online claimed to know exactly what happened to Haun. But based on what little evidence they had, Cannon said law enforcers knew it wasn't true.
Preston Haun said he was told his son was separated at 2 a.m. Saturday from the person he originally went to the party with and got a ride with some other kids who dropped him off about a mile from where he was hit.
The Utah County Sheriff's Office announced a $5,000 reward for information about the teen's death that could lead investigators to the driver or the vehicle that hit him. Anyone with information is asked to call the sheriff's office at 801-851-4010.
