Columbia, SC (WLTX) - A Midlands family is mourning the loss of their 20-year-old daughter, as deputies need your help in understanding what happened in the hours leading up to her death.

News19 sat down with the parents of Mayra Sanchez, the young woman who was shot in the upper body on Wednesday. She was then dropped off in a wheelchair by her boyfriend who fled the scene, according to deputies.

Lewis was arrested and charged with obstruction of justice and misprision of felony for failing to call police when he dropped off the victim at the hospital.

"There is no deeper pain than that of losing a child," said Mr. Sanchez in Spanish. The news of their daughter came as a terrible surprise when her boyfriend knocked on their door and told them Mayra was in the hospital.

News19 is not showing the faces or giving the first names of the Sanchez family because investigators have not yet found the person responsible for Mayra's murder.

Mayra was a graduate of Richland Northeast High School, and her mom described her as a "happy person."

Mayra's dad told News19 he suspected something was wrong when her boyfriend, 24-year-old Albertus Lewis, visited the home very late at night. They say they had already told Lewis to stay away from their property but he didn't seem to listen.

Sgt. John Carwell is the investigator on the case with the Richland County Sheriff's Department. He says they're looking into a few shootings that happened that same day.

"We’re aware of two other shootings that happened in that general vicinity of where we suspect this murder took place, which is the Percival Road, Decker Boulevard area," said Carwell. One of the other shootings they're investigating happened at Mi Casita.
