A search warrant for a blood sample housed at Tampa General Hospital for Jaron Skipper reveals the father tested positive for cocaine, amphetamine and cannabis while he was being treated for his injuries.
The warrant states that detectives want to test the hospital's blood sample because it has been too long to take a new sample.
The Polk County Sheriff's Office confirmed earlier this month that detectives were starting a criminal investigation into Skipper, who crashed a pick-up truck into the back of a City Bus with his 4-year-old son and 7-year-old daughter inside.
The warrant also reveals that deputies found 3 pain pills in a plastic bag in Skipper's pants pocket.
The warrant describes the injuries to the children as a fractured spine and fractured skull.
The Sheriff's Office said Skipper has not been cooperating in the investigation.
A spokesperson for PCSO says they are waiting for the results of their own toxicology report. Skipper has not been charged with any crime, but the warrant lists several potential charges. Those charges include child abuse, DUI with serious bodily injury and DUI with property damage.
Skipper and his daughter have been released from the hospital. Family members tell ABC Action News, the 4-year-old boy is still in the hospital in critical condition.
