A man who was conditionally released to a San Diego County home will be returned to a state hospital following a hearing Friday.
Alvin Ray Quarles, 63, who is classified as a sexually violent predator, was placed in a home in Borrego Springs last winter following 25 years in state prison and around a decade at a state hospital. He received treatment there as a sex offender.
But on Nov. 5, Quarles – dubbed the “bolder-than-most” rapist – was arrested and booked into county jail in Vista for an alleged violation of his release conditions.
During a brief court hearing on Friday afternoon, Quarles appeared before San Diego Superior Court Judge Marian Gaston and denied violating any conditions of his release.
The nature of the alleged violation was not discussed. Both a prosecutor and an attorney representing Quarles declined to comment.
Quarles could have had a hearing to contest the allegation, but he waived his right to it and requested a transfer back to Coalinga State Hospital, where he had previously undergone treatment.
He is due back in court Jan. 23 for additional proceedings regarding the alleged violation.
Quarles pleaded guilty in 1989 to four counts of forcible rape for a series of sex assaults at knifepoint that began in 1985, according to appellate court records. Some of the assaults took place after break-ins of homes and motel rooms; a few were committed while forcing the victim’s husband or boyfriend to watch.
Three of Quarles’ victims viewed Friday afternoon’s hearing remotely. The rapes occurred in Pacific Beach, Mission Beach, Old Town and National City.
He lived in Paradise Hills at the time of his first arrest, in February 1988. In addition to the rapes, he pleaded guilty to two robbery charges and six counts of burglary. He received a sentence of 50 years to life in prison.
The state Department of Corrections gave Quarles credit for a year spent in jail and shaved off nearly half the original sentence with credit for time served. Sentencing laws have changed and rapists now serve longer terms.
After 25 years in prison, Quarles was civilly committed to the Department of State Hospitals for treatment as a sexually violent predator. He later petitioned for conditional release, which involves placement at a residence where SVPs are monitored and must abide by stringent conditions.
Last year, a judge ordered his conditional release, but the search for a suitable residence proved difficult, leading another judge to order him released as a transient. The Borrego Springs home was intended to be a temporary location until state hospital officials could find a suitable fixed residence.
