The doctors were in court Thursday for a hearing about the case. Donaldson waived his right to appear at the hearing.
The next court date is scheduled for October 30, 2018.
Donaldson is accused of shooting and killing four people over a span of six weeks in 2017 in the Seminole Heights neighborhood of Tampa.
Donaldson was arrested on Wednesday, November 29 and charged with four counts of First-Degree murder in connection to the murders of Benjamin Mitchell, Monica Hoffa, Anthony Naiboa and Ronald Felton. Donaldson's lawyers entered a not guilty plea on his behalf at his arraignment in December.
