A Queens social worker who posed as a relative to steal $220,000 from an 85-year-old man in her care got off with just five years’ probation yesterday.

Jennifer Robinson, 37, of Cambria Heights, had faced up to 15 years in prison. But Queens Supreme Court Justice Fernando Camacho took it easy on Robinson.

In 2009, she listed herself as a niece of the late Walter Witko, a dementia patient, to steal his assets, proseuctors said.
