The March death of a 22-year-old Georgia Southern University student from DeKalb County was drug-related, according to a GBI autopsy.

Bradley Frietas, a Decatur High graduate, died of accidental acute heroin and fentanyl toxicity, a GBI medical examiner determined.

“There is no suspicion of foul play” in Frietas’ death, GBI spokeswoman Nelly Miles told AJC.com on Thursday.

However, the GBI is continuing to investigate his death.

“In light of concern with opioids, there’s a shift in how they handle these investigations,” Miles said.

The body of 20-year-old junior Malik Jones was discovered Tuesday night in his apartment, the GBI said Thursday in a statement.

An autopsy was performed Wednesday by a GBI medical examiner. Results are pending.

When questioned Thursday about the deaths occurring at the same housing facility, Miles would not comment on any possible connection.
