A 29-year-old man is in jail after investigators say he started a sexual relationship with a 13-year-old girl.

Carlos Ordonez is charged with aggravated sexual assault of a child younger than 14. Ordonez is accused of starting a physical relationship with the teen in 2012 after meeting her at a party. He was 27 years old at the time.

Court documents state the girl's mother found out about the relationship and reported Ordonez to the police.
