ORLANDO, Fla. — Police have arrested a second person in connection to the death of an Orlando toddler that a child protection team doctor said could be considered a "torture case."

Johnathan Pursglove, 25, has been charged with aggravated manslaughter of a child in the death of 2-year-old Jayce Martin, who died in mid-July in the family's Bethune Drive home.

Jayce's mom, 24-year-old Victoria Toth, already faces the same charges in the case, which the Orange County Medical Examiner ruled a homicide. Pursglove and Toth were in a relationship, the Orlando Police Departrment stated.

An autopsy of Jayce's body revealed evidence of blunt-force trauma, investigators say. 

"The trauma to Jayce was so severe that it caused a perforation in the (gastrointestinal) tract, leading to contents of the bowel entering Jayce's body; causing an infection (Peritonitis); resulting in his death," an arrest affidavit for Toth said.

Dr. Mark Kesler, a child protection team physician, told investigators that Jayce's death was preventable.

"He said Jayce suffered unnecessarily and that this could be considered a 'torture case' due to this child being severely neglected," the affidavit stated.

Dr. Shaista Safer, a pediatric gastroenterologist at Orlando Health who is not connected to the case, said, "Peritonitis can be deadly because if you develop an accute peritonitis, you not only have the infection in the abdominal wall, it starts to leak into blood stream, and that could cause shock, and that can cause death.”

Toth was released from jail on bond last week.
