That information led them to an overgrown horse pasture near 3600 S. 5200 West, where the girl’s body was found sometime before 6 a.m. A 15-year-old boy, who was the sole suspect, was arrested and will likely be charged with murder, according to West Valley City Police Chief Lee Russo. Police said they planned to pursue murder charges against the boy, who was still being questioned late Friday.

Police are investigating after a Homestead Police officer shot and killed a man, Thursday afternoon.

Police were able to find the girl behind a row of homes by tracking her cell phone, though the device was not found on the body.

The West Valley City Police Department said Kayley Vijil left her family’s house in the suburb of Salt Lake City around midnight, apparently with her parents’ permission.

A 15-year-old boy is in custody, accused of killing a 12-year-old girl in a field near her home. His name was not immediately released.

“He asked me: ‘I’ve been waiting for you to see my fort setting it up and I want you to go see my fort in the abandoned house, ‘” said Mia Montano, who lived nearby. “And she said “No I can’t it’s too late””.

Police said the child does not have a history of running away and the police also said that they don’t have a history with this family.

The girl’s parents had been out looking for her throughout their neighborhood before finally telling police in person at their local convenience store, The Deseret News reported.

“This isn’t about parenting”, Russo told reporters during a press conference. Investigators said there appeared to be evidence of a struggle at the scene. However, Russo said Kailey’s mother knew her daughter was leaving with the boy, but it was unclear if she knew where her daughter was going or why she allowed her to leave.
