SACRAMENTO (CBS13) – An arrest has been made months after a woman in her 60s was attacked and raped. The suspect is only 15 years old.

The assault happened in early February and Sacramento sheriff’s detectives finally linked evidence at the scene to the teenager.

“My mom and our family is very lucky that he didn’t kill her,” the victim’s son, who wished to remain anonymous, said.

His 64-year-old mother thought she was safe in her own home until she was brutally attacked, raped and robbed inside her south Sacramento apartment.

“She don’t enjoy life no more, and she has flashbacks all the time, and she just don’t feel safe anymore,” the son said.

The victim reported being choked, thrown by her hair and beaten.

Deputies arrested the suspected attacker on Wednesday — stunned the attacker was so young.

“When I learned he was 15, I couldn’t believe it,” the man said.

“I think it shocks the conscious somewhat to think of somebody so young committing such a violent crime,” Sacramento County sheriff’s Sgt. Jason Ramos said.

Deputies say the unnamed teenager doesn’t have much of a criminal record, but they will compare his DNA with other assaults in the area.

“There’s always the potential that he could be connected to unsolved sexual assault cases,” said Ramos.

“He’s a kid. And to commit a horrible crime, a heinous crime like this, it’s unbelievable,” the victim’s son said.

The victim’s son is still coming to terms with what a kid could be capable of doing.

“He’s a menace to society,” he said.

The teen faces felony charges.
