Authorities are uncovering more details surrounding the death of two-year-old Jayce Martin, and a second arrest has just been made in the case.

Jayce was discovered unresponsive in his bedroom, so police were contacted. When they arrived, they found the boy to be malnourished and heavily bruised. His mother, 24-year-old Victoria Toth, told first responders that Jayce began feeling ill on July 15. The following day, he began vomiting and was acting very lethargic. He was sick for about three days before she found him laying face down in his own vomit.

Investigators noticed several holes in the walls of the apartment indicating that someone had punched the holes in the wall out of anger. They also noticed a broken toilet lid and seat in the bathroom. When medical examiners uncovered the boy’s cause of death, his mother was immediately arrested and charged with aggravated manslaughter of a child. The two-year-old died from blunt force trauma to the abdomen area. The punch literally caused the toddler insides to explode, and the boy spent the following days slowly slipping into a coma. An autopsy revealed that visiting a doctor could have saved this child’s life.

Further investigation revealed that the child’s biological father urged the mother to take Jayce to the doctor when he became ill, but she never did. 25-year-old Johnathan Pursglove was the live-in boyfriend to Victoria Toth, and police now know he played a role in the boy’s death as well. Pursglove was arrested and charged with aggravated manslaughter of a child.
