King County judge gives Jayvantre Sin 17½ years for 2022 sexual assaults
Jayvantre Sin received the minimum 210-month sentence after pleading guilty to sexual assault charges stemming from attacks in Tukwila and Seattle. The assaults occurred weeks after he escaped from a low-security juvenile facility in Ephrata.
A King County judge sentenced Jayvantre Sin to 210 months in prison — 17½ years — on Friday, Oct. 16, for two sexual assaults committed in 2022 after he escaped from a state juvenile facility.
Sin pleaded guilty in September to second-degree rape and indecent liberties. He had initially faced first-degree rape, indecent liberties and two counts of first-degree robbery; prosecutors later dropped the robbery charges. The 210-month term is the minimum sentence for the offenses, prosecutors said, and victims and police supported the recommendation.
Prosecutors said Sin raped a 16-year-old girl at gunpoint at Southcenter Mall in Tukwila in August 2022. Nine days later, court documents say, he beat and sexually assaulted a 25-year-old woman who was walking home from work in Seattle.
One victim described the lasting impact in court. “I was just trying to get home safely. I did nothing wrong, but that night, my life changed,” she said. She recounted being strangled and struck as she pleaded for the assault to stop.
The attacks took place less than two months after Sin escaped from Sunrise Community Facility in Ephrata. The low-security group home had no fences and unlocked doors, according to court documents. Sin had been sent there at 16 by the state juvenile rehabilitation program to serve time for felony convictions that included robbery, attempted eluding, residential burglary and car theft.
Sin also had nine felony and misdemeanor convictions in Oregon under a false name and a history of removing his ankle monitor, according to the account presented in court. The King County Prosecuting Attorney’s Office said it was not told of his escape before receiving the sexual assault cases. The state Department of Children, Youth and Families previously said the facility followed its escape procedures, including notifying local law enforcement and issuing a warrant.
Senior Deputy Prosecutor Jocelyn Cooney said Sin’s actions and flight from the crimes reflected a “violent and powerless coward.” Sin told the court he regretted his criminal history and said it was shaped by an unstable childhood. “I’ve done a lot of bad things, and I feel deep remorse,” he said.
A victim told Sin she hoped one day she could live without fear. After serving the 17½-year term, he must appear before a sentencing board, which will decide whether he should be released. Prosecutors said the sentence could extend to life in prison.
