BELL COUNTY, Texas (KXXV) — The father of Serenity Baker, the 14-year-old Roy J. Smith Middle School student stabbed and killed on campus in March, is suing Killeen Independent School District and Evolv Technologies Inc. individually and on behalf of his daughter’s estate for damages and wrongful death.
The Incident
According to the lawsuit filed Sept. 16 in Bell County District Court, Serenity Baker was stabbed in the neck with a 3.5-inch tactical folding knife by another student on March 10.
The suit states Serenity collapsed in a school hallway where no staff or security personnel were present to provide immediate aid. Instead, a fellow student attempted to apply pressure to the wound before Serenity "bled out in the hallway and died."
Security System Failure
The lawsuit alleges that the Evolv weapons detection system installed at the school was not functioning at the time of the incident.
Thadius Baker, Serenity's father, claims in the lawsuit that Evolv Technologies marketed its system as "a reliable safeguard against knives, firearms, and other threats," but the technology was "plagued with detection failures."
The document also states that the Federal Trade Commission sued Evolv for making false claims about the effectiveness of its technology.
Prior Warning Signs Ignored
According to the lawsuit, the school district had knowledge of bullying and disputes involving the perpetrator and maintained a "bully reporter system," but "no effective intervention occurred."
However, 25 News previously reported that key findings from the district's investigation that bullying was not determined to be a factor; the investigator found no evidence that bullying contributed to the incident. No prior reports of bullying were filed by the students involved, though officials noted students were not interviewed.
The lawsuit also claims that "parents and community members had repeatedly raised concerns about lax security, inconsistent bag checks, and ineffective safety enforcement at KISD campuses."
Legal Claims
The lawsuit includes multiple claims against both defendants:
Against Killeen ISD:
- Wrongful death and survival action
- Violation of child's constitutional rights under Texas law
- Negligence in providing a safe environment
- Premises liability and negligent security
- Negligent hiring, training, and supervision
- Gross negligence
Against Evolv Technologies:
- Products liability for design and marketing defects
- Negligence in deployment and maintenance
- Breach of warranty
- Fraudulent misrepresentation
- Gross negligence
The father is seeking damages against both Killeen ISD and Evolve Technologies, claiming their conduct rose to the level of gross negligence.
25 News reached out to Killeen ISD for a comment on the lawsuit, but the district said it does not comment on litigation.
Below is a statement from Evolv Technology in response to the complaints filed against the company in this lawsuit:
"We are deeply saddened by the tragic death of Serenity Baker and send condolences to her family, school, and community at-large. As the complaint states, the Evolv Express system at Roy J Smith Middle School was not in use on the day of the incident. We intend to vigorously defend our position. Evolv stands firmly behind our technology. Our focus remains on our mission: helping schools and communities create safer environments."
Below is a statement from the attorney representing Thadius Baker:
"We represent Thadius Baker, the father of Serenity Baker, whose tragic passing after being attacked on the campus of Roy J. Smith Middle School on March 10, 2025 has devastated her family, friends, and the community as a whole. Through this litigation, we are seeking justice for Serenity and her family, and we aim to hold accountable all those who caused or contributed to the incident that took Serenity’s life. We are in the early stages of the lawsuit at this time, and there may be additional parties brought into the suit as more information is discovered through the court process. We ask for the community’s continued thoughts and prayers for Serenity’s family and friends as this case makes its way through the justice system."
