NORMAN, Okla. (KFOR) — A Norman woman pleaded guilty to hitting and severely injuring another woman more than two years ago.

Doorbell video shows Sara Polston barreling down the street of a Norman Neighborhood.

Moments later, she crashed into 20-year-old Micaela Borrego's car blocks away, critically injuring her.

Polston was drunk. Tests show she was nearly twice the legal limit, and also had marijuana in her system.

Polston pleaded guilty Wednesday afternoon.

Polston's attorney tells us she will be sentenced in December.
