A Grand Junction man is facing 13 charges of sex assault on child.
22 year old David Diesburg was arrested after four girls under the age of 11 reported a detailed account of sexual abuse by their “family friend” and babysitter according to the Mesa County Sheriff's Office.
Diesburg moved to Grand Junction from Iowa with the victims and their parents and has been living with them since October.
The victim's parents say they would let Diesburg babysit while they went to work.
Diesburg is accused of having sex with one of the young girls and touching them all while playing a sexually oriented game.
Diesburg is behind bars on a $150,000 bond.
