Arizona Teen Accused Of Sexually Assaulting At Least 18 Girls
San Tan Valley, Arizona (CNN) An Arizona teenager is accused of sexually assaulting at least 18 girls.
18-year-old Tyler Kost has been arrested twice this week and is facing 25 new charges Friday afternoon.
He went to school with most of the alleged victims.
"In these cases, in every one of these incidents that we're aware of at this point, Tyler was somebody who was known, who was befriended, who was trusted by not only the victims, but by the families. And there was a clear breach of trust from all of the accounts of the victims, as somebody who is highly manipulative, very charismatic and charming in how he presented himself and things obviously turned," says Sheriff Paul Babeu, Pinal County, Arizona.
A student first approached authorities about Kost in March.
Investigators say one girl became suicidal, others withdrew from school and two left the state to escape him.
The cases date back to 2011.
