A Berks County man is facing homicide charges in the beating death of his 89-year-old mother, District Attorney John Adams announced Wednesday.

Edna Shifflett died on May 23; the coroner's office ruled last Tuesday that her death was a homicide, the result of injuries she suffered in an assault inside her home on April 25.

Edna Shifflett told a doctor treating her in the emergency room at Reading Hospital that night that her son, Charles Shifflett, hit her several times in the head with a closed fist, according to court documents.

She suffered severe bruising on the left side of her head and bleeding on her brain, police said.

Charles Shifflett, 64, has been behind bars in the Berks County Jail on charges of aggravated and simple assault and harassment since the alleged beating.

Adams told 69 News that he expects to file homicide charges against him soon.
