Two Baltimore sisters charged in the death of their paraplegic mother pleaded guilty to first-degree vulnerable adult abuse in Baltimore City Circuit Court on Monday.

Tia Sewell, 27, and Sharon Jones, 26, face up to six years in prison under the plea agreement.

Sentencing is scheduled for Dec. 28.

Their mother was 40-year-old April Montford. Paramedics discovered Ford Feb. 29, 2008, after being called to her house in the 400 block of W. Franklin St.

According to court records, police said Montford, who was paralyzed from a 1985 gunshot wound, was lying on bedsheets that had been unchanged for years.

She was covered in bed sores, infected with gangrene and had been infested by maggots and lice.

Her daughters were supposed to be caring for her.
