RICHARDSON  (CBSDFW.COM) – The family of Devin Byrd says they don’t believe a woman’s story that she suffered an epileptic seizure the day she ran over the 12-year-old boy in Richardson and left the scene.

Byrd remains in a medically-induced coma and in critical condition at Children’s Medical Center in Dallas.

Richardson Police say Elaine Burbridge, 62, struck the boy with her car last week and left the scene.  She surrendered to officers five days later.

Family members are at Byrd’s side and family spokeswoman Courtney Hopping says they hope he will make a full recovery.

“I think he’s a very strong boy, coming up to be a man,” she said.  “And yes, I think if there’s anybody who can recover from this, it’s him.”

But Hopping says there are too many holes in Burbridge’s story.  “I think the police report conflicts with her having an epileptic seizure because my understanding is she made it home safely.”

Hopping, a former prosecutor with the Dallas County District Attorney’s office, says she believes the charge against Burbridge should be Aggravated Assault With Serious Bodily Injury, rather than the current charged of Failing to Stop and Render Aid.

Burbridge’s attorney says his client has no recollection of hitting the boy.  “She feels absolutely horrible that Devin was hurt,” Scott Palmer said, and added that his client is taking the incident seriously.

“Although we understand the family’s extremely upset, and frankly, they should be upset, this accident was just that: an accident,” said Palmer.

Richardson police say the investigation is ongoing.
