Justin McGriff, the man accused of killing a HART bus driver in May, has been ruled incompetent to stand trial, the state attorney's office says.
McGriff is charged with first-degree murder in the stabbing death of Thomas Dunn.
Back in May, the Tampa Police Department responded to a call of a bus driver being stabbed by a passenger at North Nebraska Avenue and East Lotus Avenue. Upon arrival, TPD began searching for the stabbing suspect and officers eventually spotted McGriff near I-275.
TPD officers detained McGriff after a short chase. McGriff was originally only charged with resisting arrest without violence, but police later announced he was charged with first-degree murder.
Since then, new safety barriers were approved to protect drivers.
When Dunn was killed, he did not have a safety partition between himself and the passenger to protect him from the attack.
McGriff has been sent to a state mental hospital for treatment.
