EL PASO, Texas (KTSM) – El Paso Independent School District officials on Tuesday named the mother who was killed in the parking lot of Tippin Elementary School on the first day of school.

Kharisma Aslee James, 33, was killed after she was hit by a vehicle driven by Roger Hawking, 58, Monday afternoon at the West El Paso school, EPISD officials said in a news release.

Hawking has not been charged by police, as of Tuesday morning. 

The names of the three children, who were injured along with James, were not released by EPISD, but they were identified as a 6-year-old girl, 7-year-old boy and 10-year-old boy. They are still in the hospital with “serious but improving” conditions, EPISD said.

James was the mother of two of the children. The third child was unrelated.

EPISD Police Chief Victor Araiza said the driver hit another vehicle in the parking lot after classes were dismissed Monday.

Araiza said the driver kept going after the collision and hit the three children. Witnesses reportedly walked over to help, telling police the driver appeared to be confused. The driver then put the car in drive, and hit the mother.

“Fault rests on the the driver that was operating that vehicle,” said Chief Araiza.

Araiza said charges have not yet been filed against the driver, but added that the investigation remains active.

The school district’s superintendent released the following statement Tuesday morning:

This morning will be a difficult one for the students and staff at Tippin Elementary. Classes will resume but not without the assistance from our counselors who will be on hand to help the children and adults who are grieving after the tragic events from yesterday.

I want to thank the Tippin family for coming together during these trying times. Their solidarity and willingness to help is a testament to the spirit of community that exists there. I have heard from many people who witnessed parents who stepped in to help assist students and tend to the injured. Their actions bring a glimpse of light to an otherwise difficult situation.

Our thoughts and prayers remain with the families of those who were affected by the tragic accident, and with the students and teachers at Tippin who today return to school.
