Arguments were heard Thursday to determine if manslaughter charges against a Des Moines doctor should be dropped.
Doctor Daniel Baldi is charged with 10 counts of manslaughter.
Prosecutors said he over-prescribed pain medication to 10 patients who later died.
Baldi’s attorney filed a brief last month that asked the charges against his client be dropped.
During a hearing Thursday morning, Baldi’s attorney argued why the case should be dismissed.
Guy Cook says in four of the cases doctor Baldi did not prescribe the medications that were in the victim’s systems when they died.
In the other cases, Baldi’s attorney says the prescription medications were within therapeutic levels.
The judge is considering the evidence and did not say when a ruling would be issued.
