DENVER -- The death of a 3-year-old girl who had been hit more than 50 times, according to court documents, has been ruled a homicide.

The child’s mother now faces additional charges in connection to the girl’s April 7 death.

The District Attorney's Office filed additional charges against 34-year-old Susie Ida Quartey on Friday. The additional counts filed are child abuse -- knowingly and recklessly causing death -- and tampering with a witness or victim.

Both are felony charges; the first with a penalty range of four to 48 years, and the second with a penalty range of one to 12 years.

Quartey originally faced charges of sex assault on a child and second-degree assault with a deadly weapon.

The girl's death had initially been classified as suspicious before the Arapahoe County Coroner's Office ruled her death a homicide.

The arrest affidavit said the girl, Jolyn Torpoh, had been hit more than 50 times with a coat hanger and a broken towel rack, and she may also have been stabbed with a piece of a towel rack and kicked.

Quartey has told investigators that she was carrying Jolyn in a sling when the child fell out and onto rocks in their back yard. Quartey's attorney, Thomas Miller, has said Quartey did not beat Jolyn.

On Friday, Quartey appeared in court to hear that a competency evaluation found her to be competent for trial.

Authorities said Quartey is from Ghana and was also under an immigration hold because her residency status was unclear.
