Jurors will begin deliberating Monday in the case of a Massachusetts pharmacist charged with murder in a meningitis outbreak that killed 76 people.

Jurors went home Friday after attorneys gave closing arguments. They are expected to return to Boston's federal courthouse Monday morning.

Pharmacist Glenn Chin is charged with second-degree murder under federal racketeering law and other crimes. He ran the clean rooms where the drugs that caused the 2012 outbreak were made.

Prosecutors say Chin failed to properly sterilize the drugs and instructed staff at the New England Compounding Center in Framingham to use expired ingredients and ignore cleaning.

Chin's attorneys argue the pharmacy's co-founder is to blame. Barry Cadden was sentenced to nine years in prison after being convicted on conspiracy and fraud charges and acquitted of second-degree murder.

A federal prosecutor says a Massachusetts pharmacist charged in a meningitis outbreak that killed 76 people knew mold and other bacteria were growing inside the filthy production rooms but chose to do nothing.

Assistant U.S. Attorney Amanda Strachan told jurors Friday that New England Compounding Center supervisory pharmacist Glenn Chin ignored warning signs that patients' safety was at risk. Strachan says Chin chose instead to "gamble" with patients' lives.

Chin is charged with second-degree murder under federal racketeering law and other crimes. He ran the clean rooms where the drugs that caused the 2012 outbreak were made.

Chin's attorney, Stephen Weymouth, told jurors that prosecutors have failed to prove how the drugs became contaminated. Weymouth says, "This is a horribly tragic death case, but this is not a murder case."
