Former Tampa Bay Rays prospect Brandon Martin was convicted Wednesday of three counts of first-degree murder for using a baseball bat to murder his father, uncle and a bystander in 2015.
In addition to the three murder counts, Martin was convicted of evading arrest, resisting arrest, stealing an automobile and injuring a police dog.
The jury is scheduled to hear testimony on Monday in the sentencing phase and prosecutors are seeking the death penalty.
The former first-round pick killed his father, 64-year-old Michael Martin; the elder Martin's brother-in-law, 51-year-old Ricky Lee Anderson; and 62-year-old Barry Swanson.
