SAN DIEGO -- A 17-year-old boy, who is accused of raping a woman at knifepoint in her College-area home just days after being released from Juvenile Hall, pleaded not guilty Thursday to nine felony charges.

Chadrick Jarrod Robertson, who was charged in adult court due to his extensive arrest background, was ordered held on $1 million bail. Judge David Szumowski scheduled a preliminary hearing for Sept. 4.

Robertson faces up to 105 years to life in prison if convicted of two counts of rape and one count each of forced oral copulation, sodomy, sexual battery, assault with intent to commit rape during a burglary, attempted robbery, residential burglary and false imprisonment, said Deputy District Attorney Patrick Espinoza.

The teenager was arrested Monday night during a traffic stop in Rolando. Investigators identified him as the alleged assailant based on DNA evidence and a description given by the 47-year-old victim, SDPD Lt. Caroline Kendrick said.

The youth allegedly climbed through an unlocked window of a home on 67th Street near El Cajon Boulevard about 4 a.m. on Aug. 13, apparently planning to commit a robbery, Kendrick said.

With a knife in hand, the intruder demanded money from the victim, Kendrick said. When she said she had none, her assailant raped her, the lieutenant said.

Genetic evidence found at the scene allegedly matched a sample taken from the teen last year when he was convicted of robbery.

Also implicating the suspect in the attack were cuts on his left ear, allegedly from a glass shattered over his head by the victim, according to police. Kendrick alleged the teen cut the victim with his knife in the arm and on her thigh with a piece of the broken glass.

The woman, who drove herself to a hospital, has since been released and is doing "very well" after receiving support from family, Kendrick said earlier this week.

Police believe the boy may also have burglarized a home near the rape victim's home that same night, the lieutenant said.

Kendrick said the teen has an extensive arrest background and was released from Juvenile Hall on Aug. 8. She said a sexual assault allegation was sent to the district attorney's office in 2007, but he was never tried for the allegation.
