A former resident of a Virginia senior living community will not stand trial in the death of a fellow resident because he has been found to be mentally incompetent, the Richmond Times-Dispatch reported.

Edward Huff, 86, has Alzheimer’s disease but had been charged with involuntary manslaughter after the Oct. 29 death of Delora Arnold, 92. Both lived at Elmcroft of Chesterfield, an assisted living and memory care community in Richmond, VA.

The charge against Huff was withdrawn March 15 on the recommendation of a prosecutor, according to the media outlet.

Arnold, the newspaper reported, died from her injuries two days after Huff attacked her in her room. The medical examiner’s office ruled her death a homicide from blunt-force trauma to the neck and chest.
