"It was quite hard to assess him," she testified. "He was upset and confused." Moseng said that Floyd told her he consumed opioids. On cross-examination, Moseng said that Floyd took Percocet, a combination of Oxycodone and acetaminophen used to treat pain."I asked him why, and he said because he was addicted," she testified.Lawyers for Chauvin on Tuesday began presenting their case in the former Minneapolis policeman's murder trial, also calling to the stand a now-retired officer who pulled over a car in which Floyd was a passenger in 2019 - a year before his deadly encounter with Chauvin.Chauvin's lead attorney, Eric Nelson, argued in court filings that the earlier arrest supported his defense that a drug overdose may have caused Floyd's death in May 2020, not a lack of oxygen caused by Chauvin kneeling on his neck for more than nine minutes, as prosecutors charge.But in cross-examination Moseng said that, despite the pills he had taken, Floyd was alert, not in respiratory distress, and did not suffer a heart attack.
