Trayvon Martin's parents published a "card of thanks" in The Miami Herald obituary page Sunday.

The note says Sybrina Fulton and Tracy Martin express their appreciation for all the public's support since their son's death. 

The notice includes a photograph of Trayvon Martin dressed in a hooded sweatshirt, similar to one he was wearing the evening he was killed.

The letter reads "words will never express how your love, support and prayers lifted our spirits and continue to give us the strength to march on."
