ORLANDO, Fla. -

The family of an Orange County teenager who was shot in the head called for more arrests in the case Tuesday.

Danielle Sampson, 15, was hospitalized in July and remains in a coma at Arnold Palmer Hospital.  Orange County investigators have said the teen was shot on her way home from church when a gunman opened fire on another car that Sampson was not riding in.

The Caribbean Passport News Magazine, Greater Orlando CARES and other community leaders plan to join Sampson's family Tuesday to hold an event  called "Wake Up Everybody" in the teen's honor.

The family says while 19-year-old Tyrone Mosby has been arrested, others involved in the shooting are still on the loose.

The family has also announced a portion of the tickets purchased for an Oct. 6  fashion show will help benefit Hope for Danielle, a foundation set up in her honor. The event is hosted by Unity in Uniform and Greater Orlando CARES.

At the news conference Tuesday, Sampson's family said they must take her out of the hospital by the end of Tuesday because they can't afford to keep her in the hospital any longer.

Sampson will be transferred to an acute rehabilitation center for two weeks where her family can learn how to take care of her.
