ROCK HILL — Police found a knife on a Rock Hill man who claimed that he was going door-to-door to raise money for an alleged operation that would remove his son’s brain tumor. After arresting him Tuesday, authorities realized that his son isn’t sick.

William Lorenzo Moffitt, 28, is charged with unlawfully carrying a weapon, soliciting without a permit and obtaining goods by false pretense, according to a Rock Hill police report. He is held at the York County Detention Center on a $3,600 bond.

Officers were called to the 2200 block of Raven Drive after receiving complaints of a suspicious man soliciting funds for a sick child. Officers found Moffitt carrying an address book and black folder with his son’s picture and medical information, the report states.

Moffitt told police he was going door-to-door to raise money because his son had a brain tumor and he needed money to have it removed, according to police. Moffitt appeared very nervous and “was shaking and sweating profusely.”

Moffitt admitted to police that he had a knife in his back pocket. Officers arrested Moffitt and discovered that he was soliciting without a permit after police already told him last week he would need to get a license through the city. Moffitt said he never went to get the permit.

Moffitt’s family later told police that Moffitt’s son is “very healthy” and doesn’t have a tumor. Moffitt was unsuccessful in pocketing money from residents.
