State (Blackwell) calls Dr. Martin Tobin. He is a physician who specializes in pulmonology and critical care. He works in Chicago. He is from Ireland, hence the accent. More than half of his patients are on respirators.

He is now talking about sleep apnea. All of his research is on breathing. Wrote a textbook on mechanical ventilation - 1,500 pages. Blackwell is holding up his book, which has been referred to as the “bible” of ventilation

The state contacted Dr. Tobin to be an expert. He declined to be paid because he thought he had something to offer about GF’s death.
