BATON ROUGE- After the state concluded its investigation into the death of Alton Sterling, the coroner’s office released a detailed report of the substances found in Sterling’s system the night he was shot. 
The report states that Sterling had high levels of amphetamines, depressant drugs, methamphtamines, opiates, THC  and some traces of cocaine. 
According to medical experts at the U.S. National Library of Medicine, mixing such drugs use can alter a person’s ability to think and may cause them to act in an abnormal manor, or cause agitation and paranoia.
