Final answer:
Gonzalez's death, occurring after ingesting six PCP pills and being found without blood or injuries, likely resulted from a drug overdose. Since PCP can cause fatal effects without visible trauma, an overdose is a plausible explanation for his death.
Step-by-step explanation:
The student asked what type of death occurred when Gonzalez, who took six PCP pills, was found dead in the back seat of a vehicle without any blood or injuries. Given the circumstances provided, it is possible that Gonzalez experienced an accidental death due to a drug overdose. PCP is a dissociative drug that can have severe effects on the central nervous system, and an overdose can be fatal without any external signs of injury.
In 2014, drug overdoses became a leading cause of accidental death, surpassing motor vehicle crashes. The majority of these deaths were from substances like heroin and opioid painkillers, but drugs like PCP also contribute to the statistics. Given that PCP can cause respiratory depression, seizures, coma, and sometimes death, it is plausible that Gonzalez's death was the result of the drug's toxic effects on the body.
Although there isn't blood or visible injuries, a drug overdose can occur without any outward trauma and still result in death. To confirm the exact cause of death, an autopsy and toxicology reports would be necessary to determine the presence and levels of PCP or any other substances in Gonzalez's system.
