Suspicious evidence found in strange disappearance of teen with family convinced he was kidnapped from remote spot

she believes her son "was taken, and he did not leave his place willingly."

Rounds' boots have been found by his camper behind a dirt pile on the property near the Utah-Nevada border, she added.

Cooley told the local outlet police found the boots within the first hour and a half of Rounds being reported missing on May 30.

"From where his grain truck was parked, his boots were about 100 yards south behind a pile of dirt just casually tossed out," Cooley said.

"He was very particular about his boots. He wears a pair, and it's always the same pair. When they wear out, he goes and buys exactly the same boots."

Police told the mother they found a spot of blood on the boots and it would be sent to a lab for tested, she said.

Cooley said there were no tire tracks in the dirt leading to or from Rounds' red pickup truck, which is suspicious because it had rained on Memorial Day weekend, when he disappeared.

The mom claimed the truck looked like it had been pressured washed when police found it. She also said the driver's seat had been scooted up in an unusual way.

Additionally, the truck was in four-wheel drive even though Rounds had complained that the four-wheel-drive had not been working, according to Cooley.

Due to his age, some have speculated that Rounds may have run away, but the Box Elder County Sheriff's Department said in  that he is listed as missing.

The missing teenager's frantic family has been working with law enforcement to look for Rounds.

"He is an old soul, farm boy at heart. All he wants to do is get up and work all day every day. He isn’t interested in partying, he isn’t interested in travel," said Wells.

"He never dated in high school. He’s not your typical 19-year-old."

Since he vanished, there has been no cell phone or credit card activity on his accounts.

A $20,000 reward is being offered to anyone who finds Rounds or knows where he might be, said the family.

Dylan Rounds is 5-foot-10 and weighs 160 pounds. He has brown hair and brown eyes and was last seen wearing jeans, a dark shirt and a flannel jacket.

Anyone with any information is being told to contact his mother, Candice Cooley, at (208) 604-3839.
