In addition to making his case for the job, Dr. Stephen Cina, a Miami forensic pathologist, will be grilled on a range of issues during the afternoon confirmation hearing.

Members of the county board say they’re concerned about Cina’s frequent job changes, his demand for a 30 percent raise — to $300,000 — over the salary paid to Dr. Nancy Jones as medical examiner, his plans for additional staffing and the consulting firm runs as a side business.

Earlier this month, Preckwinkle nominated Cina after he won the support of Dr. Edmund Donoghue, who was medical examiner before Jones.

Cina has had a 20-plus year career in Texas, Colorado, Wyoming and Florida. He is associate medical director at the University of Miami Tissue Bank.

From 2007 to 2011, he was deputy chief medical examiner in Broward County, Fla. Earlier this year, he lost a bid for the top job at the Fort Lauderdale office.
