Mother of Trayvon Martin tweets that God is healing her

Sybrina Fulton says a lot of work to be done

SANFORD, Fla. - The mother of Trayvon Martin tweeted Tuesday that her heart is healing but added that a lot of work remains.

Sybrina Fulton, whose 17-year-old son was shot and killed in Sanford last year, tweeted that God is healing her but also reminding her that "we have a lot of work to do" as she referenced peace protests that are scheduled to take place.

George Zimmerman, the neighborhood watch leader who shot Martin, was found not guilty in the Miami teen's death on Saturday by a six-woman jury.

A march and rally for Martin is scheduled in Orlando on Wednesday, and the Rev. Al Sharpton says there will be vigils and rallies in 100 cities this weekend to press for federal civil rights charges against Zimmerman.

Zimmerman's acquittal has touched off protests around the country.

Sharpton announced the plan Tuesday at a news conference outside the Justice Department with several ministers. He did not say which cities are involved, but did say the rallies and vigils will be staged Saturday at federal buildings.

"God is healing my heart this very moment. But as I watch so many people come together, he reminds me that we have a lot of work to do. ?#?PeaceProtest ?#?TrayvonMartinForever"

The Justice Department is investigating whether Zimmerman violated Martin's civil rights when he shot the teen in a gated community.  Zimmerman said he fired his gun in self-defense.

The jury acquitted Zimmerman of second-degree murder and manslaughter charges.
