TAMPA, Fla. -- A psychiatric evaluation is due back Tuesday for the man accused of shooting and killing four people in Seminole Heights last fall.

  • Competency exam results due on accused Seminole Heights killer
  • Howell Donaldson III charged with 4 counts of first-degree murder
  • Attorneys say Donaldson III suffering from mental health issues

Dr. Richard Carpenter, Ph.D., a court-approved psychologist, is expected to submit his report Tuesday on Howell Donaldson III. 

Donaldson III, 24, is facing four charges of first-degree murder.

Donaldson III's attorneys had previously filed a motion asking that his mental status be evaluated by specialists. 

Seminole Heights residents and police were on edge last fall, starting when 22-year-old Benjamin Mitchell was shot to death Oct. 9.

Two days later, 32-year-old Monica Hoffa, was slain. And on Oct. 19, Anthony Naiboa, 20, was killed after taking the wrong bus home from his new job. On Nov. 14, 60-year-old Ronald Felton was shot and killed.

Donaldson III was arrested Nov. 28. 

The mental evaluation will help determine if Donaldson is mentally competent to proceed with a trial. 

A competency hearing has been scheduled for Thursday.
