Chadrick Robertson reportedly raped the woman a day after being released from Juvenile Hall in August 2008. He pleaded guilty February 19 to a felony rape charge.
Robertson was arrested August 18 during a traffic stop. Prosecutors say DNA on a cigarette found in the victim's home linked him to the crime.
According to authorities, Robertson climbed through an unlocked window of a home on 67th Street near El Cajon Boulevard about 4 a.m. August 13, 2008 apparently with the intent to commit a burglary.
The intruder demanded money from the victim, while carrying a knife. The victim said she had none and then he raped her, police said.
During the sexual assault, the victim cut her attacker with a drinking glass. Then, he hit her with a glass, causing her to bleed profusely, police reported. Authorities also said the victim was bleeding so badly during the hour long ordeal that she begged Robertson to let her go to the hospital, which he finally did.
Robertson, who turns 18 in June, said he was remorseful.
The judge told the victim he would never come back to harm her again.
