The Queens man who accused his father of being possessed by the devil before plunging a knife into his chest this week has been charged with murder, authorities said. 

Jaimie Walker, 30, allegedly stabbed family patriarch Loandows Walker, 72, around 6:30 a.m. inside the Hempstead Avenue apartment in Queens Village.

The victim’s 70-year-old wife, the couple’s other son, 31, and their daughter-in-law, 29, were meanwhile poisoned in the home during a religious ceremony, but are expected to survive, police sources said. 

Police are investigating whether Walker had poisoned them. 

Walker, who was initially hospitalized for a psychiatric evaluation, was charged later in the evening with murder and criminal possession of a weapon, cops said.

His arraignment was pending Friday afternoon.
