EAST VILLAGE — An East Village man was arrested and charged with murder after police say they found his great-grandmother dead and tied up in the East Village apartment they shared Friday night.

Ella Mae Green, 82, was found unresponsive with her wrists and ankles duct taped together inside the Lillian Wald Houses near East Sixth Street and FDR Drive, around 5:30 p.m. Friday, officials said.

Paramedics arrived soon after, and pronounced her dead at the scene, according to police.

The woman's 39-year-old granddaughter, who police identified as the suspect's mother, was also tied up, but managed to free herself and call 911, according to the NYPD.

Police later arrested Gary Bias, 23, who was charged with both murder and attempted murder in the second degree, the NYPD said.

Police and prosecutors on Saturday said that after a family dispute Bias attacked Green, knocking her head against the ground before binding and gagging her with the tape around 8 a.m. Friday.

Around 5 p.m. that night, Bias allegedly attacked his mother, knocking her to the ground while punching and kicking her, stomping on her face, and binding her with the duct tape, then tying an object around her neck, according to a criminal complaint filed by the Manhattan District Attorney's Office.

It was not immediately clear what caused the dispute, police said

Bias' mother was taken to Bellevue Hospital and treated for her injuries, according to police.

An attorney for Bias did not immediately return a request for comment.
