Lake Brantley student faces new child sexual abuse material charges, FDLE says

FDLE has added 10 child sexual abuse material charges against Lake Brantley High School student Isabelle Valdez, deepening a case that already had Seminole County parents watching the school safety response in Altamonte Springs. Investigators said the new case grew out of a February review of Valdez’s cellphone, months after an anonymous FortifyFL tip triggered arrests tied to an alleged plan to kill a classmate.

The Florida Department of Law Enforcement said June 11 that Valdez, 15, of Altamonte Springs, was arrested on 10 counts of possession of child sexual abuse material. FDLE said she was already in custody on unrelated charges when the arrest affidavit for the new case was presented, adding another layer to a prosecution that has already moved through juvenile and adult court issues.

According to FOX 35, the child exploitation investigation began after Altamonte Springs police reported finding a video file on Valdez’s phone that appeared to show the sexual abuse of children. Agents later secured a warrant and examined the device, allegedly uncovering multiple videos, including some involving children as young as three years old. Valdez remained in the Seminole County Jail as the investigation continued.

The new charges sit on top of the earlier Lake Brantley case that brought Valdez and another student, Lois Lippert, 14, under intense scrutiny. Police arrested the two on January 23, 2026, after an anonymous FortifyFL tip reported a potential threat to a Lake Brantley student. Court records reported in multiple outlets say the alleged target was an unknown male classmate whom the girls believed resembled Sandy Hook shooter Adam Lanza.

Prosecutors have described the alleged plan as a blood ritual or occult-inspired plot. In March, a judge ordered both teens held without bond. Earlier charges in the case included attempted premeditated murder, attempted felony murder, aggravated stalking, armed burglary, attempted aggravated child abuse, and possession of a weapon on school property.

Valdez also wrote to a judge in May blaming online influences and years of bullying, saying she had been groomed online and asking to return home to her parents. The case has now become a test of how quickly school-safety warnings, digital evidence and law-enforcement intervention can escalate into separate criminal investigations. For families at Lake Brantley, the clearest signal is that the case remains active, the custody has not changed, and the scrutiny around student reporting and campus safeguards is not easing.
