ORLANDO, Fla. (AP) - Police in Orlando have identified the gunman who killed a surgeon in a parking garage at Florida Hospital and then fatally shot himself.

Authorities said Friday that 53-year-old Nelson Flecha had a patient-doctor relationship with the multi-organ transplant surgeon, 41-year-old Dmitriy Nikitin. They said a motive was still being determined.

The shooting occurred Thursday near the elevators on the first floor of the garage used by employees and patients' families.

Nikitin taught at the University of Central Florida's College of Medicine. Last year, he was part of a surgical team that set a Florida Hospital record for the most number of transplants ever done in a weekend.
