Reyna Martinez, a 13-year-old Boulder Hill girl, is still missing after four days, the Kendall County Sheriff's office confirmed Wednesday afternoon. 

Detective Sergeant Joe Jasnosz of the Kendall County Sheriff's office said Reyna was last seen Sunday morning at her home in the 0-100 block of Long Beach Road. 

According to a family member, the Plank Junior High student has deleted all of her family from her Facebook account.  She has friends in Oswego, Montgomery and Plainfield, the family member said. 

Reyna was last seen wearing a black tank top, white Abercrombie hooded jacket, blue jeans, and black Converse shoes with a pink near the laces. 

Jasnosz confirmed that she is still missing and that foul play is not suspected. Reyna's mother, Karie Anne Marie Degand, reported to the Sheriff's office that her daughter ran away. 

Anyone who may have seen Reyna or has information on her whereabouts is urged to contact the Kendall County Sheriff's office at 630-553-7500.
