Authorities say a 23-year-old South Carolina man has been charged in the fatal shooting of his girlfriend, who was left in a wheelchair outside a hospital.

The Richland County Sherriff's Office announced Monday that Albertus Lewis faces a charge of murder. Previously he was charged with obstruction of justice.

Authorities said 20-year-old Mayra Sanchez was found about 4:30 a.m. on July 5 at a hospital in Columbia, the state capital, and pronounced dead by doctors. Deputies say Lewis put Sanchez in a wheelchair and left.

The woman's mother, Guadalupe Sanchez, tells WLTX that the family had a restraining order against Lewis.

It wasn't immediately known if Lewis has an attorney.
