Trayvon Martin's parents 'disgusted' by Zimmerman verdict

The parents of Trayvon Martin say they were shocked and disgusted by the decision to acquit his killer George Zimmerman.

Father Tracy Martin told Good Morning America that he felt the ruling was "unfair and devastating".

Family lawyer Benjamin Crump confirmed that they would be investigating other legal courses to prosecute Mr Zimmerman.

George Zimmerman, 29, was cleared on Saturday of the death of unarmed 17-year-old Trayvon Martin in Florida last year.
