The 17-year-old victim told police the assault occurred on Dec. 27 as she walked home near the 11300 block of Expo Boulevard.
According to the affidavit, the victim was attacked by a man wearing a ski mask and gloves.
The victim tried to fight off the attacker, but was beaten, choked and sexually assaulted, the affidavit stated.
The suspect fled after the attack, but the victim was able to get a glance at the man's face and a tattoo located on his stomach.
San Antonio police released sketches of the suspect in mid-January that were aired on local media outlets.
The affidavit stated multiple tips led to a person of interest later identified as Hartsfield.
Hartsfield denied his involvement in the sex assault, but DNA from a previous burglary arrest matched the DNA found under the victim's fingernails, the affidavit stated.
Hartsfield was arrested and charged with aggravated sexual assault.
Below are the sketches police released to the media.
