South Carolina police have filed negligence and abuse charges against two people who allegedly left an elderly relative in the same chair for six months, which police say caused her death from a blood clot, PEOPLE confirms.

Barbara Beam was 82 when she died on Jan. 2, 2015. On Jan. 21 of this year, Beam’s sister, Carole Howell, and her nephew, David Howell, were both charged with abuse or neglect resulting in the death of a vulnerable adult.

Relatives allegedly told investigators that Beam could not walk on her own, and that it had been months since they’d seen her get up from her seat.

Beam, according to police, was found slumped over in the chair without a pulse.

The medical examiner that handled Beam’s autopsy ruled her death a homicide by neglect.

Both mother and son are being held on an unspecified amount of bail, and information regarding their attorneys was not immediately available Thursday.
