Shane William Riley, 22 of Vacaville

A 24-year-old Vacaville man charged with the October 2019 fatal stabbing of his mother pleaded no contest last week to second-degree murder and a Solano County Superior Court judge found him not guilty by reason of insanity, The Reporter has learned.

Court records show that Shane William Riley, who appeared June 3 in Department 1, waived his right to a jury trial, entered the no-contest plea and admitted to using a deadly weapon.

With the plea, Riley did not admit guilt but essentially stated he would offer no defense, and Judge Jeffrey C. Kauffman, based on a doctor’s report, found him not guilty due to insanity.

Riley was represented by Deputy Public Defender Sara Johnson, and Chief Deputy District Attorney Paul Sequeira appeared on behalf of the DA’s Office during the morning session.

Kauffman ordered Riley, who remains without bail in the Stanton Correctional Facility in Fairfield, to return for sentencing at 9 a.m. July 1 in the Justice Center in Fairfield.

At sentencing, Riley faces a maximum punishment of 15 years to life in a state hospital and will be subject to parole supervision for life, court records indicate.

The case was referred to MHM Services, which contracts with state and local agencies for behavioral services in community settings, for evaluation before the sentencing date.

The latest development in the case comes coming after an earlier report from the Department of State Hospitals declaring the defendant was mentally competent to help in his own defense and also after the judge compelled him to involuntarily take anti-psychotic medication.

In April 2020, Kauffman ordered Riley to be confined to one of five California state hospitals for two years. The judge has periodically reviewed Riley’s mental competency and placement.

At earlier proceedings in the case, Riley, after the judge heard the report on the defendant’s mental competency, was to be sent to a secure treatment facility operated by MHM Services Inc., which has offices in Vallejo.

On July 7, 2020, Riley was admitted to the Jail-Based Competency Treatment. On July 27, Kauffman reviewed yet another periodic progress report in the case, according to court records.

Early on in the case, Kauffman received and reviewed a doctor’s report about Riley’s mental competency to understand court proceedings and deemed him competent to stand trial, but a subsequent report suggested that may not be so.

But Riley was eventually deemed mentally competent and criminal proceedings were reinstated.
