LYNNWOOD, Wash. -- (KCPQ) -- A Snohomish County man will spend less than three years in prison for his role in the death of an 18-year-old girl.

The details in this story are shocking.

Brian Valera, 20, was sentenced Thursday for giving 18-year-old Alyssa Noceda drugs, raping her, then trying to hide her body after she died of a drug overdose.

Q13 News spoke with Alyssa’s mother, who says she feels anything but a sense of justice after the man responsible for her daughter’s death will spend less time in prison than a car thief.

Alyssa Noceda died last February of a drug overdose at a party. On Thursday, Brian Varela, the man prosecutors say was responsible for her death, was sentenced for his crimes.

“I’m heartbroken,” said Pierson. “She deserves justice and she’s not receiving it.”

Police say it all happened inside a mobile home near Martha Lake. Court documents say Noceda used marijuana and snorted prescription drugs Valera shared with her – but she soon lost consciousness, and her lips turned blue.

Court documents say Valera sent pictures and text messages to his friends saying she had passed out and that he had sex with her, but he never called first responders for help.

“She died from an acute combined overdose of fentanyl and a generic for Xanax,” said Pierson.

One of Valera’s friends eventually called police, and when they searched his home days later they found Noceda’s body stuffed into a crate.

Valera was sentenced to less than three years in prison for second degree manslaughter, third degree rape and unlawful disposal of remains.

“He chose not to do anything. He knew what was going on, he made that obvious in the text message and the photos he sent to his friends,” said Pierson. “He knew every single thing that was going on with her and he chose to do nothing. There were no mistakes in there.”

Valera could have called for help and avoided drug possession charges thanks to the state’s Good Samaritan law. Instead, court records say he raped his victim, tried to conceal his DNA evidence on her body and planned to bury her in a hole near Marysville.

“I’m just appalled. It’s a joke. A slap on the wrist for taking someone’s life and violating another human being,” she said.
