Matthew Shelton Convicted of Abusing Students at Robert Semple Elementary in Benicia

Matthew Joseph Shelton Convicted Nearly Two Decades After a Napa Acquittal Let Him Return to the Classroom

BENICIA, CALIFORNIA (October 29, 2026) – A 44-year-old former fifth-grade teacher identified as Matthew Shelton has been convicted of sexually abusing four students at Robert Semple Elementary School in Benicia.

Solano County officials are saying that a jury returned its verdict on Thursday, October 22, following a five-week trial. Matthew Shelton was found guilty of 11 of 12 felony counts of lewd acts with a child under 14, and the jury declared a mistrial on the remaining count, according to KQED.

Prosecutors said Shelton inappropriately touched three female students more than 20 times inside his classroom in 2022, and also presented evidence of a 2019 incident involving a child on a field trip to Oakland, ABC10 reported. The case came to light in December 2022, when girls in his class reported the touching to their principal, and students later disclosed more serious allegations to Benicia police.

Shelton was remanded into custody without bail and faces life in prison at his December 16 sentencing. Two women who accused him of abuse as third-graders in Napa also testified, nearly two decades after a jury acquitted him of those allegations in 2008.

The school’s principal was placed on leave the day after the verdict. Benicia Unified still faces three civil lawsuits alleging it failed to protect students when it hired Shelton months after that acquittal.

After the acquittal, California’s Commission on Teacher Credentialing issued Shelton only a private admonishment, a rare discipline hidden from the public and expunged within three years. Evidence at trial appeared to show the state had notified Benicia Unified of that admonishment, raising questions about what administrators knew.

A 2024 lawsuit alleges the principal helped keep negative information out of reference checks after Shelton resigned, and he was soon hired as an assistant principal in West Contra Costa Unified, the Vallejo Sun reported. Two bills that would have created a searchable database of educators reported for misconduct were killed this year, though a new law lets the state discipline administrators who skip required checks with prior employers.

Could stronger information sharing between schools and the state have kept him out of a Benicia classroom?

Liability for Benicia School Sexual Abuse

The abuser bears primary responsibility, but California law can also hold a school district accountable for its administrators’ failures. Under Government Code section 815.2, a public entity is liable for injuries caused by employees’ negligence within the scope of their jobs. Courts recognize that school personnel have a special relationship with students and owe them a protective duty of reasonable care. Teachers and administrators are also mandated reporters, and Code of Civil Procedure section 340.1 gives survivors extended time to sue entities that failed to take reasonable steps to prevent childhood sexual assault. These cases often turn on several responsibilities:

• Screening: Districts are expected to examine a candidate’s history, including prior complaints, credential discipline, and reasons for leaving past jobs.
• References: Former employers can face responsibility if they misrepresent a known history of misconduct with students.
• Supervision: Administrators must reasonably monitor staff they know or should know may pose a risk to children.
• Reporting: Employees who reasonably suspect abuse must report it to law enforcement or child welfare authorities, not handle it internally.
• Response: Schools should document student concerns, separate the employee from students when appropriate, and cooperate with investigators.

Courts have applied these principles directly to abuse in schools. In C.A. v. William S. Hart Union High School District (2012), the California Supreme Court considered a teenage student’s claim that his high school’s head guidance counselor sexually harassed and abused him over several months. The trial court dismissed the district, but the Supreme Court reversed, holding that a district can be vicariously liable under section 815.2 when administrators negligently hire, retain, or supervise an employee they knew or should have known posed a danger to students. The court stressed that liability must rest on evidence of negligence, not the misconduct alone. Every case depends on its facts, but C.A. remains a cornerstone for families seeking accountability.

Why Educator Misconduct Often Goes Unreported

Abuse by a trusted educator is more common than many parents realize. A 2004 U.S. Department of Education report estimated that 9.6% of students in grades 8 through 11 had experienced some form of sexual misconduct by a school employee, based on a nationally representative survey. The same review found that only about 6% of students formally reported it. Children often stay silent, fearing they won’t be believed, especially when the adult is well liked. Families can take several practical steps:

• Listen first: Staying calm and believing a child makes it more likely they will share the full story.
• Write it down: Recording dates, the child’s own words, and who was present can help investigators later.
• Report outside: Contacting police or child protective services ensures an independent review beyond the school’s internal process.
• Request policies: Parents can ask for a school’s written rules on staff-student boundaries and how complaints are handled.
• Seek support: A counselor experienced with childhood trauma can help a child rebuild a sense of safety.

Survivors of educator misconduct can carry its effects for years. Schools, districts, and licensing agencies all share responsibility for systems that catch warning signs before another child is harmed. When those systems fail, survivors and their families have the right to learn what administrators knew and when. California law also allows survivors to pursue compensation for counseling, medical care, and other harms. Accountability is often what drives the reforms that protect the next generation of students.
