Missing Dylan Rounds: Utah investigators issue warning to anyone involved in teen farmer's disappearance
The circumstances of his disappearance appear suspicious: Rounds' mother suspects foul play and investigators haven’t ruled it out.
Meanwhile, tips are scarce and a large-scale search of the area has turned up nothing.
And police say interviews with numerous people connected to the teen turned up no leads.
"If somebody is involved with Dylan’s disappearance, they need to know we're not going to go away," Chief Deputy Cade Palmer, of the Box Elder County Sheriff’s Office, told Fox News Digital Wednesday.
Law enforcement spent weeks canvassing the area in an operation that has, so far, included K-9s, drones and horses.
